“Certain minerals have been known to draw moisture from the foam and cause the foam to degrade more quickly… you may get a shorter life span” –u/batmannorm, Brooklyn Bedding new Copper Flex

Copper-infused foams are often marketed as offering antimicrobial, cooling, and pressure-relief benefits, but they can also have some downsides when it comes to long-term durability. Some users have observed that minerals like copper may draw moisture into the foam, which over time can contribute to the material breaking down more quickly.

This may show up as softening, sagging, or the foam becoming brittle and less responsive, reducing the overall lifespan of the mattress. While Brooklyn Bedding generally has a strong reputation for craftsmanship and durability within the bed-in-a-box category, it’s important for buyers to keep realistic expectations, particularly when choosing a mattress that relies on specialty foams.

People looking for a mattress to last over a decade may want to consider the hybrid version, which combines coils with foam for added durability. Budget-focused shoppers may still find excellent short-to-medium-term value if they understand these trade-offs upfront, especially when returning CopperFlex 12 by Brooklyn Bedding under the trial period if it doesn’t meet expectations.

“copper infused foam… oxidizes… getting brittle while shedding a green verdigris dust. Infused foam… is a marketing gimmick and rarely performs as well as the original product.” – Roger1855, Brooklyn Bedding new Copper Flex

Some people say copper-infused foam helps with cooling, pressure relief, and germs. But not everyone believes it works. One reason is that copper can change over time. It might oxidize, making the foam brittle or leave behind green dust. That brings up concerns about how long the foam lasts and whether it’s safe to sleep on for years.

This doubt doesn’t stop with copper. Other materials like charcoal, titanium, or CBD get the same reaction. Many people think these are just marketing tricks. Some gels can make memory foam feel a little nicer, but they usually don’t fix heat or health issues in a big way.

If you’re thinking about getting the CopperFlex 12”, take a moment to weigh the pros and cons. Especially if you have skin sensitivities or care about how long the mattress will last.

“It’s extremely firm but I think it’s built to last is why” u/Garrettwx, Brooklyn Bedding new Copper Flex

Brooklyn Bedding’s CopperFlex 12″ mattress has a medium-firm feel, rated at a 7 on the firmness scale, so it offers a happy balance between softness and support for side, back, and stomach sleepers. Intended for sleepers weighing up to 250-300 lbs per sleeper, it has excellent stability as a mattress for sleepers needing pressure relief, but heavier sleepers should also consider the Titan Plus for durability in dense support foams.

The mattress has zipper cover on comfort layers of quilted pressure-relief foam, CopperFlex cooling memory foam, and VariFlex IQ memory foam for adaptive comfort. The support layers consist of zoned lumbar support in foam, VariFlex transition foam, and a durable high-density base, or Ascension X coils if hybrid, all of which are intended to allow a healthy spinal alignment while sleeping.

It is also an excellent mattress for motion isolation if you prefer not to be disturbed when sleeping next to someone else. Even though copper-infused foam can improve cooling above average levels, many customers express concerns about mattresses longevity that has foam that becomes oxidized and brittle, and buyers should take durability in any form of foam into consideration before purchasing.

“I’ve had the copperflex pro for about 3 weeks. No complaints so far. It’s medium firm, not plush but pretty comfy.” –u/Dear_Equivalent_9692, Brooklyn Bedding new Copper Flex

The CopperFlex 12” by Brooklyn Bedding offers a medium-firm feel, typically rated around 7 out of 10 on the firmness scale, which provides a balance of comfort and support. It’s designed to suit side, back, and stomach sleepers, making it a versatile choice for many sleeping positions.

The comfort layers include pressure-relieving quilt foam, CopperFlex memory foam, and Pressure Relieving Quilt Foam, which work together to provide cushioning without sacrificing support. Beneath these, the zoned lumbar support, VariFlex transition foam, and high-density support foam offer proper spinal alignment and durability.

During the first few weeks, many users experience a “breaking-in” period where the mattress feels slightly firmer before softening to a more comfortable level. Motion isolation is excellent, which is particularly beneficial for couples. While most sleepers report good initial comfort, some may wonder how safe it is to sleep on copper-infused materials, especially over long-term use.

“I would suggest the hybrid version… consider your preferences and body profile before making your decision.” – batmannorm, Brooklyn Bedding new Copper Flex

When purchasing a mattress like the CopperFlex 12 by Brooklyn Bedding, it is important to factor in individual preferences such as sleep position, body weight, and firmness options. The CopperFlex 12” is rated medium-firm (around 7 out of 10), meaning it can work for side, back, and stomach sleepers. The mattress supports a maximum individual sleeper weight of 250 to 300 lbs, although heavier sleeper may prefer the Titan Plus model.

In terms of comfort, the mattress has Pressure Relieving Quilt Foam, CopperFlex memory foam to remain cool and provide contour, and softer comfort foam. After that is VariFlex transition foam, zoned lumbar support for relief on targeted pressure points, and high density, breathable support foam for durability and spinal alignment – or Ascension X coils in the hybrid version to improve responsiveness and cooling airflow.

The CopperFlex 12″ mattress does a good job at motion isolation but if a sleeper made a choice between the two hybrids I would opt for the hybrid model because of the superior edge support and increased bounce. It’s also worth considering more than just performance when considering any specialty foam mattress, so not only should you think about performance and pressure relief, but potential long-term durability and concerns about copper infused foams.

One of the main selling points of the CopperFlex 12” by Brooklyn Bedding is its use of copper-infused memory foam, which is marketed as having natural cooling and antimicrobial properties. In theory, the copper particles help draw heat away from the body, keeping sleepers cooler throughout the night.

However, many users report that the actual cooling effect is minimal, especially for hot sleepers or those living in warmer climates. While the copper infusion may slightly improve temperature regulation compared to traditional memory foam, it’s often not enough to fully resolve heat buildup on its own.

For those who prioritize staying cool at night, the hybrid version of the CopperFlex, which includes a layer of coils for increased airflow, tends to perform better. The coil system helps dissipate heat more effectively than all-foam models. Overall, while the CopperFlex 12” offers some cooling features, it may fall short of the expectations set by its marketing.

Edge support is an important but often overlooked factor when choosing a mattress, especially for couples or anyone who regularly sits or sleeps near the edge. The CopperFlex 12” by Brooklyn Bedding, being an all-foam mattress, offers moderate edge support compared to hybrid models. Its comfort system—featuring pressure-relieving quilt foam, CopperFlex memory foam, and comfort foam—provides contouring and softness, while the VariFlex transition foam and high-density support base help reinforce the perimeter.

That said, some users may still notice slight compression when sitting or lying near the edge. While the mattress performs well for most sleepers, heavier individuals or those who frequently use the edges might experience more noticeable sinkage over time. In comparison, the hybrid version, which incorporates Ascension X coils, typically delivers better edge support and a sturdier feel along the sides.

Overall, the CopperFlex 12” offers decent edge stability for an all-foam model, though edge-conscious buyers may prefer the hybrid.

For couples or lighter side sleepers, motion isolation is an important consideration if they are easily awakened by their partner’s motion throughout the night. The CopperFlex 12” by Brooklyn Bedding does very well in this category due to the Three layers of foam which include their CopperFlex memory foam, quilt foam, and comfort foam, which all help to cushion motion and absorb energy across the surface of the mattress.

So, if one partner is moving, shifting, or getting out of bed, the other will have virtually no disturbance in their sleep. The reports from users rated solid in motion control, so the CopperFlex 12″ is a great choice for couples or pet owners to avoid involving as much motion into their sleeping experience. Although hybrid models, such as innersprung or latex, can provide reasonable motion isolation, an all-foam model such as the CopperFlex 12″ will provide better motion isolation properties.

If you are looking for a solid sleep surface for not waking up anytime until your alarm goes off, the CopperFlex 12″ by Brooklyn Bedding is a great option for a quieter sleep surface.

The CopperFlex 12” by Brooklyn Bedding comes with a 120-night sleep trial and a lifetime warranty, offering customers peace of mind when making their purchase. The trial period allows buyers to test the mattress at home and decide if it meets their comfort and support needs. If dissatisfied, customers can initiate a return for a full refund, but some users report that the return process can involve several steps, such as trying the mattress for a minimum period (typically 30 nights) before a return is approved.

When returning CopperFlex 12” by Brooklyn Bedding, buyers may be asked to donate the mattress or coordinate a pickup, depending on their location. The lifetime warranty covers manufacturing defects like sagging or foam cracking but doesn’t cover normal wear and tear or misuse. It’s also important to understand how to avoid voiding its warranty, such as using a proper foundation and following care guidelines.

The CopperFlex 12” mattress by Brooklyn Bedding offers a good mix of comfort and support. It uses copper-infused memory foam and has a medium-firm feel. There’s also extra support for the lower back and low motion transfer, which works well for people who sleep on their side, back, or stomach.

Some users like how comfortable and durable it feels. Others aren’t sure if the copper foam really helps with cooling or holds up over time. Edge support is better than expected for an all-foam bed, and motion doesn’t spread much across the surface. Off-gassing (the smell when you first open it) goes away fairly quickly.
The mattress comes with a 120-night trial and a lifetime warranty. But it’s important to read the warranty rules closely to avoid problems later.

Overall, the CopperFlex 12” is a solid option for people who want firm support and relief from pressure, but it’s not perfect. It helps to set clear expectations before buying.
