Is the Plank Firm Mattress Safe?
When choosing a mattress, safety and quality are just as important as comfort.

Firmness Level: Who Is It Best For?
- Back and stomach sleepers who require a firm surface to maintain proper spinal alignment
- People with back pain who may benefit from reduced sinkage and better weight distribution
- Sleepers who prefer a flatter, more supportive feel rather than the deep hug of softer mattresses
The mattress is also flippable, offering both a firm side and an extra-firm side, allowing you to choose the level of support that works best for you. Complaints and real user experiences suggest that while some find it too firm, others appreciate the unique support it provides.
If you’re someone who enjoys an ultra-firm mattress with customizable firmness levels, the Plank Firm mattress could be a great fit for your sleep needs.
Plank Firm Construction & Materials
The Plank Firm mattress is built with high-density support foam layers and quilted bottom for long-lasting support. Its main layers include:
- Quilted Top Layer – A tight, flat surface for maximum firmness
- High-Density Support Foam – Provides strong, durable support
- Optional Cooling Cover – A Glaciotex cooling cover can be added for enhanced temperature regulation
This simple yet effective design ensures a durable and supportive sleeping surface without unnecessary softness.
Motion Isolation & Edge Support
If you share a bed, you know how disruptive it can be when your partner tosses and turns all night. Fortunately, the Plank Firm mattress does an excellent job at minimizing motion transfer. Its dense foam construction absorbs movement well, making it a great choice for couples—especially if one person is a light sleeper.
Beyond motion isolation, edge support is another important factor, and the Plank Firm mattress delivers here too. Thanks to its high-density foam base, the mattress provides a sturdy and supportive perimeter. Whether you’re sitting on the edge to get ready in the morning or sleeping near the side, you won’t feel like you’re about to slide off. If you’re looking for a mattress that keeps movement to a minimum while offering solid edge support, the Plank Firm is a strong contender.
Does the Plank Firm Sleep Hot?
One common concern with memory foam mattresses is heat retention, which can make sleeping uncomfortable—especially for hot sleepers. The Plank Firm, however, addresses this issue with an optional GlacioTex cooling cover designed to regulate temperature and enhance airflow.
For those who tend to overheat at night, upgrading to this cooling cover can make a noticeable difference. It works by drawing heat away from the body, keeping the sleep surface cooler and more breathable. While the standard Plank Firm mattress may sleep a bit warm for some, the cooling cover helps create a much more comfortable sleep environment.
If you struggle with night sweats or find yourself kicking off the covers, this upgrade could be worth considering. With its firm support and temperature-regulating option, the Plank Firm mattress offers both comfort and a cooler night’s sleep.

Durability & Longevity
The Plank Firm mattress is designed for long-term durability, thanks to its dense foam construction. High-density support foam is known for its resilience, meaning this mattress will maintain its firmness and shape for years to come, even with regular use.
To ensure it stays in top condition and to avoid voiding your Plank Firm mattress’ warranty, it’s important to follow the care instructions provided by Brooklyn Bedding. Using a proper foundation or bed frame and avoiding excessive moisture exposure can help prolong the mattress’s lifespan.
Brooklyn Bedding also backs the Plank Firm mattress with a lifetime warranty offering peace of mind with your purchase. This warranty reflects the brand’s confidence in the mattress’s longevity, making it a solid investment for those looking for a firm, supportive sleep surface that won’t wear down easily over time. With proper care, you can expect years of reliable comfort and support.
Off-Gassing: Is There a Smell?
If you’ve ever unboxed a new mattress, you may have noticed a slight odor—this is known as off-gassing and is common with bed-in-a-box mattresses. The Plank Firm mattress is no exception and may have a mild smell when first unpacked due to its compression packaging. However, there’s no need to worry.
Since the Plank Firm mattress is CertiPUR-US certified, it’s made without harmful chemicals like formaldehyde or heavy metals, ensuring that any initial smell is non-toxic and temporary. Simply allowing the mattress to air out in a well-ventilated room should help the odor fade within a few hours to a couple of days.
Most sleepers find that the smell disappears quickly and doesn’t linger. If you’re sensitive to smells, keeping windows open or using a fan can speed up the process. Once fully aired out, the Plank Firm provides a clean and safe sleep environment.
Is the Plank Firm Worth It?
- Prefer firm or extra-firm sleep surfaces
- Need strong back and spinal support
- Want a flippable mattress with two firmness levels
- Seek a fiberglass-free, CertiPUR-US certified mattress
One of the best ways to determine if this mattress is right for you is by taking advantage of the Plank Firm mattress’ trial period. This allows you to test it out at home and see if the firm feel truly suits your sleep needs. However, if you prefer a plush, contouring feel that hugs your body, this may not be the best fit. Ultimately, the Plank Firm mattress is ideal for sleepers who appreciate firm support and a mattress designed for long-term durability.
