Is The OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress A Good Mattress For You?

The OTTY Pure+ Hybrid 4000 Pocket Sprung mattress features are designed to keep you cool, supported, and undisturbed all night long. But this mattress isn’t for everyone.

If that’s you, a firmer option like the OTTY Firm Hybrid might be a better fit.

This firmness level works best for side and back sleepers, as it cushions the hips and shoulders and keeps the lower back supported. It’s also a great match for couples, offering a neutral feel that suits different sleep preferences and minimizes motion transfer.

Medium

  • 5.5 out of 10
  • Offers enough cushioning to relieve pressure points while maintaining support for spinal alignment.

Sinkage

The sinkage on the OTTY Pure+ Hybrid 4000 is moderate and balanced. Its medium feel and dual layers of pocket springs combination let you experience a gentle cradle. It is just enough to cushion your shoulders, hips, and lower back. This level of sinkage supports the mattress’s promise of delivering pressure relief and proper spinal alignment. It helps reduce strain on joints and muscles through the night.

This controlled sinkage allows your body to relax into the surface just enough for a cozy sensation, but still keeps your spine aligned and your movements easy. You don’t sink too deeply, which means it’s easier to change positions and stay cool.

It’s also well-suited for anyone dealing with mild back or joint discomfort, as the responsive springs and dense foams work together to promote healthy posture and reduce strain.

Encapsulated Pocket Springs

  • 2000 individually wrapped coils
  • Medium firmness rating
  • Maximum support with minimum motion transfer

The encapsulated pocket springs in the OTTY Pure+ Hybrid 4000 feature 2,000 individually wrapped coils. Each spring moves independently, meaning they contour to your body’s unique shape and movements. This reduces pressure on key areas like your hips, shoulders, and back, while also minimizing motion transfer.

The medium firmness rating strikes a perfect balance between gentle comfort and firm support, making the mattress adaptable for a wide range of sleep needs.

High-Density Support Foam

  • Specially designed Reflex Foam
  • Provides comfort
  • Additional support on top of the spring layer

The High Density Support foam is made from specially designed Reflex foam. It is positioned directly above the spring layer, and it acts as a responsive transition between the soft upper layers and the firmer spring base.

This foam absorbs and distributes pressure evenly, giving your body extra support. It reduces the risk of pressure buildup, improves spinal alignment, and prevents that “bottoming out” feeling when you lie down. By working with the springs to support your body’s natural curves, the Reflex Foam helps relax muscles, ease joint stress, and promote uninterrupted deep sleep.

Cooling Memory Foam

  • Expertly designed memory foam with drilled holes
  • Extra air circulation
  • Reduces heat retention

The Cooling Memory foam in the OTTY Pure+ Hybrid 4000 is engineered with drilled holes to boost airflow and reduce heat retention. With its enhanced breathability, this foam layer keeps the sleep surface cooler and more comfortable throughout the night, helping users stay asleep longer without waking up sweaty.

By maintaining a stable, comfortable temperature, this cooling layer directly supports restful and restorative sleep. It also gently contours to your shape, relieving pressure while maintaining airflow.

High-Density Base Foam

  • Solid foundation
  • Ensures the mattress lasts long
  • Keeps it stable

The High Density Base foam in the OTTY Pure+ Hybrid 4000 acts as the solid foundation of the mattress, providing long-term durability and structural stability.

This base layer supports all the upper comfort and support layers, preventing sagging and helping the mattress maintain its shape over time. It adds more durability and support. This keeps the entire mattress stable, which is key to maintaining proper spinal alignment throughout the night.

Response Time

The response time of the OTTY Pure+ Hybrid 4000 is fast, thanks to its dual layers of pocket springs and reflex foam support layer. Unlike traditional memory foam mattresses that can feel slow, this hybrid quickly adjusts to your movements and returns to shape almost instantly.

This fast response helps maintain a more adaptive comfort and reliable support. A quick response time feels more responsive and easier to move on, which is especially helpful for combination sleepers who change positions frequently.

Bounce

The bounce on the OTTY Pure+ Hybrid 4000 comes mainly from its 4,000 individually wrapped pocket springs, which give the mattress a responsive, slightly springy feel. This bounce prevents you from feeling stuck.

Each spring reacts independently, so the bounce feels controlled and targeted. This bounce makes the mattress easier to move around on, great for combination sleepers. The bounce keeps the surface feeling lively and durable over time.

OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress – Cooling Features

The OTTY Pure+ Hybrid 4000 has well-engineered cooling features that work together to create a sleep surface that stays fresh and breathable all night. These include bamboo and charcoal-infused memory foam, drilled foam layers for airflow, and Airflow Side Support technology.

Overall Performance

The cooling features of the OTTY Pure+ Hybrid 4000 are a combination of bamboo and charcoal-infused memory foam, drilled foam layers, and Airflow Side Support technology allows heat to escape and fresh air to circulate through the mattress. These features help maintain a comfortable temperature and prevent sweaty wake-ups. However, cool sleepers might not fully benefit from these features.

Heat Regulating Memory Foam

  • Keeping you at the perfect temperature
  • Memory foam infused with Bamboo and Charcoal
  • Regulates heat properly

The heat-regulating memory foam in the OTTY Pure+ Hybrid 4000 creates a cooler, cleaner, and more breathable sleep surface. Infused with bamboo and charcoal, this foam naturally wicks away moisture, resists odors, and disperses body heat. Unlike traditional memory foam that can trap heat, this upgraded version helps maintain a steady, comfortable temperature throughout the night, perfect for hot sleepers.

Airflow Technology

  • Airflow Side Support
  • Offers an edge-to-edge sleeping surface
  • Aids in temperature regulation

The Airflow Side Support in the OTTY Pure+ Hybrid 4000 reinforces the mattress edges for a larger, more stable sleeping surface, and it enhances temperature regulation through better air circulation. This means you can sleep right up to the edge without feeling like you’ll roll off, while the built-in airflow channels help heat escape more efficiently.

For anyone who sleeps hot, this feature makes the mattress feel more spacious, supportive, and consistently cool.

Cooling Memory Foam

  • Expertly designed memory foam with drilled holes
  • Extra air circulation
  • Reduces heat retention

The Cooling Memory foam in the OTTY Pure+ Hybrid 4000 uses expertly drilled holes to increase airflow and reduce heat retention.

For users, this means fewer sweaty wake-ups and a more comfortable and breathable sleeping environment.

Breathability

The breathability of the OTTY Pure+ Hybrid 4000 features a bamboo and charcoal-infused memory foam, drilled foam layers, and Airflow Side Support technology. These elements work together to promote continuous airflow throughout the mattress, allowing heat and moisture to escape rather than build up.

This level of breathability maintains a stable, dry, and hygienic sleep environment. The OTTY Pure+ allows for natural temperature control and freshness, which extends the mattress’s lifespan and improves nightly comfort. It also reduces the risk of bacterial growth or unpleasant odors.

Temperature Regulation

The temperature regulation in the OTTY Pure+ Hybrid 4000 helps keep it cool, comfortable, and undisturbed sleep by combining bamboo and charcoal-infused memory foam, drilled foam layers, and Airflow Side Support.

These elements work together to actively pull heat away from your body and allow air to circulate freely throughout the mattress. This keeps the surface temperature steady, preventing the common problem of heat buildup that leads to sweating and discomfort.

OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress – Sleeping Positions

The OTTY Pure+ Hybrid 4000 Pocket Sprung mattress is best suited for side and back sleepers. With its medium feel and layered design of memory foam and pocket springs, the mattress offers the right balance of cushioning and support needed for these positions.

Side sleepers benefit from the pressure-relieving memory foam that gently cushions the shoulders and hips, preventing pressure buildup. The individual pocket springs conform to the body’s curves, helping keep the spine aligned and reducing joint strain. Back sleepers also experience excellent support, as the mattress holds the lower back in a neutral position while preventing the hips from sinking too deep.

Overall Performance

The OTTY Pure+ Hybrid 4000 performs exceptionally well for side and back sleepers. It delivers support and comfort. For side sleepers, the memory foam comfort layers relieve pressure on the shoulders and hips, while the 4,000 pocket springs provide adaptive support, keeping the spine aligned. This reduces discomfort and helps the body fully relax.

Back sleepers benefit from the mattress’s ability to support the natural curve of the spine. The medium feel and reflex foam layer help cradle the lower back while preventing it from sinking too deeply.

Side Sleepers

  • Medium feel cushions pressure points like hips and shoulders
  • 4,000 pocket springs provide adaptive support and spine alignment
  • Memory foam layers contour to the body for balanced comfort and lift

The OTTY Pure+ Hybrid 4000 is an excellent choice for side sleepers. The medium feel gently cushions the hips and shoulders. The 4,000 pocket springs adapt to the body’s shape to keep the spine aligned. This combination of contouring and support ensures users don’t wake up with sore joints.

The memory foam layers relieve pressure and encourage muscle relaxation, while the spring support keeps the body in a natural alignment. It reduces strain on the spine and joints. This leads to fewer sleep disruptions, deeper sleep cycles, and better recovery overnight, so you wake up feeling refreshed.

Back Sleepers

  • Medium surface keeps the lower back supported without sinking
  • Reflex foam and pocket springs work together for balanced support
  • High-density base foam adds stability and prevents sagging over time

The OTTY Pure+ Hybrid 4000 delivers the kind of structure and alignment that back sleepers need. The medium surface keeps the hips and lower back from sinking too far, while the Reflex foam and pocket springs work together to evenly distribute weight and maintain the spine’s natural curve. This balance of firmness and flexibility ensures proper posture and reduces the risk of waking up with back pain.

Stomach Sleepers

  • Medium feel may be too soft to keep the hips properly elevated
  • Memory foam layers add comfort but might lack the firmness needed for core support
  • Cooling layers and airflow tech help stomach sleepers avoid overheating

The OTTY Pure+ Hybrid 4000 isn’t fully tailored to stomach sleepers, but it still offers some value for lighter or occasional front sleepers. The cooling memory foam and airflow technology prevent heat buildup. It’s important for stomach sleepers who tend to sleep more flush against the mattress.

These features help improve comfort, especially for those who dislike sleeping hot. Additionally, the gentle contouring from the memory foam offers surface softness, easing tension on the chest and ribs.

Max. Weight

The OTTY Pure+ Hybrid 4000 supports a maximum weight of 250 to 300 lbs per sleeper, which ensures that the mattress can handle a wide range of body types without compromising its structure or comfort. This capacity helps fulfill its promise of providing consistent support, durability, and comfort over time, especially important for couples.

This weight limit gives users confidence in the mattress’s build quality and longevity. With 4,000 pocket springs, high-density foams, and reinforced edges, the mattress maintains its shape and support under pressure, reducing the risk of sagging.

Heavy Sleepers

The OTTY Pure+ Hybrid 4000 performs reasonably well for heavy sleepers. It offers a sturdy, well-constructed design with 4,000 pocket springs, high-density support foam, and a solid base layer.

These features work together to provide extra reinforcement, reduce sagging, and maintain proper spinal alignment. While the medium feel may still be slightly too soft for some, the mattress does a job of delivering on its promise of comfort and support within its weight range.

OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress – Couples Suitability

The OTTY Pure+ Hybrid 4000 is highly suitable for couples. It’s designed with high-performance materials. With 4,000 individually wrapped pocket springs, the mattress offers excellent motion isolation, meaning one partner’s movements won’t disturb the other.

The Airflow Side Support also ensures edge-to-edge sleeping space, so both partners can enjoy the full width of the mattress. Additionally, the medium feel hits the right spot for comfort and support.

Credits: OTTY

Overall Performance

The overall performance of the OTTY Pure+ Hybrid 4000 for couples is excellent. It’s 4,000 pocket springs that work independently to minimize motion transfer, so one partner’s movements won’t disturb the other. The Airflow Side Support adds edge stability, meaning both partners can sleep comfortably to the edge without sagging.

Couples who share a bed every night will benefit the most from this design. It promotes deeper, more restful sleep by reducing disruptions and ensuring that both people get the support they need without compromising comfort.

Edge Support

  • Reinforced perimeter using Airflow Side Support technology
  • Maintains consistent firmness and shape to the edge
  • Prevents “roll-off” feeling when lying or sitting near the edge

The edge support in the OTTY Pure+ Hybrid 4000 has been reinforced with Airflow Side Support technology. This maximizes the usable sleep surface. For couples, this means both partners can comfortably stretch out. It also makes getting in and out of bed easier and safer, especially if one partner tends to move around or sleep close to the edge.

Maintaining consistent firmness from center to edge helps keep your body properly aligned. This even supports reducing disruptions and helps your muscles stay relaxed, allowing you and your partner to enjoy deeper and undisturbed sleep.

Motion Isolation

  • Decent motion isolation
  • 4,000 individually wrapped pocket springs move independently
  • Layers of high-density memory foam absorb and dampen movement

The motion isolation in the OTTY Pure+ Hybrid 4000 creates a calm, undisturbed sleep surface. With 4,000 individually wrapped pocket springs that move independently and layers of high-density memory foam, the mattress absorbs movement instead of transferring it across the bed. This means if one person shifts, turns, or gets out of bed, the other person is far less likely to feel it.

This feature contributes directly to restful and restorative sleep, especially for light sleepers or couples with different schedules. By minimizing nighttime disruptions, both partners can stay in deeper stages of sleep longer. It helps promote a peaceful sleep environment where you can both wake up refreshed.

Sex

  • Medium feel offers a balanced surface
  • 4,000 responsive pocket springs provide subtle bounce and support
  • Cooling and breathable layers help prevent overheating

The OTTY Pure+ Hybrid 4000 is well-suited for sex. It offers a medium feel that has the right balance between comfort and responsiveness. The 4,000 responsive pocket springs provide a gentle bounce that supports natural movement without too much resistance. This makes it easier to change positions and stay mobile during intimate moments.

The mattress also features cooling and breathable layers, including bamboo and charcoal-infused foam, which help prevent overheating, keeping things more comfortable and less sweaty. This combination of bounce, support, and temperature control enhances sleep and the intimacy experience.

Maximum Support

The Maximum Support feature of the OTTY Pure+ Hybrid 4000 is thanks to the advanced combination of 4,000 individually wrapped pocket springs, high-density support foam, and a base layer. This layered support system delivers targeted pressure relief and spinal alignment.

This helps the mattress offer consistent, full-body support across all sleep positions, especially for side and back sleepers. This reduces the risk of sagging or uneven wear over time.

Super King

The Super King option of the OTTY Pure+ Hybrid 4000 is a spacious version of the mattress. It is designed to deliver the same premium features, just on a larger scale. It offers a luxurious amount of sleeping space, typically 180 x 200 cm. With more room to stretch out, roll over, or sleep in your preferred position, each person enjoys a personalized and undisturbed sleep zone.

This larger size helps couples, families, or anyone who enjoys the extra space. Combined with the mattress’s strong edge support and motion isolation, the Super King maximizes usable surface area and comfort, making it easier for both partners to sleep without bumping into each other or feeling cramped.

OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress – Shipping

The OTTY Pure+ Hybrid 4000 makes the buying experience easy with flexible shipping options that fit your lifestyle. Whether you just want the mattress dropped at your front door for free or you’d rather have it delivered straight to your room, unpacked, and your old mattress taken away, OTTY’s got you covered.

These options are great, especially if you live alone, have limited mobility, or just don’t want to deal with the hassle of setup.

OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress – Unboxing

The unboxing process for the OTTY Pure+ Hybrid 4000 is designed to be simple and user-friendly. The mattress arrives vacuum-sealed and rolled up in a compact box, making it much easier to move through doorways, staircases, or tight spaces than a traditional mattress. Once you position the box in your room, just cut the plastic wrap, and the mattress quickly expands to its full size within a few hours.

You don’t need special tools, and the lightweight packaging makes it manageable even if you’re setting it up solo. Plus, for those who want even less effort, OTTY offers premium delivery services that include unboxing, setup, and even old mattress removal.

OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress – Off-Gassing

The off-gassing performance of the OTTY Pure+ Hybrid 4000 is excellent, thanks to its use of CertiPUR-US and OEKO-TEX certified foams, which are low in volatile organic compounds (VOCs) and free from harmful chemicals.

While there may be a faint “new mattress smell” upon unboxing, it’s mild and typically fades within a few hours to a day in a well-ventilated room. It means you can start using the mattress more quickly. The use of bamboo and charcoal-infused foam also helps naturally neutralize odors and speed up the freshening.

OTTY Pure+ Hybrid 4000 Pocket Sprung Mattress – Trial Period

The OTTY Pure+ Hybrid 4000 comes with a 100-night trial period. This gives users over three months to test the mattress in the comfort of their own home. This trial allows you to get a feel for the mattress through nightly use, temperature changes, and natural body adjustments.

This trial period is good for users, especially for those unsure about making such a big purchase online without trying the mattress in person. It reduces the risk of buyer’s remorse and offers peace of mind, knowing you have the option to return it for a full refund if it doesn’t meet your expectations.
