Plank offers two ultra-firm mattress options, available in both all-foam and hybrid designs, each crafted with high-density foam layers for superior support. The Plank Firm Luxe features a core of hundreds of individually encased steel coils, making it the most popular Plank mattress due to the added contouring and motion isolation benefits provided by the coils.
Offering the firmest, flattest sleep solution on the market, Plank is endorsed by the American Chiropractic Association and helps to reduce spinal stress, improve lumbar support, and alleviate back pain. With just a simple flip of the mattress, you can choose between a firm or ultra firm comfort level.
Additionally, Plank offers an optional GlacioTex Cooling Cover upgrade on both mattress models for people who tend to sleep hot. Designed with cool tech fibers that help remove excess body head and keep you sleeping cool all night long.
Never feel your back dip and never opt for the floor again. Plank’s extra firm support (a ten on the firmness scale) will keep you firmly supported all night long.
Features & Benefits
More About the Plank Firm Luxe
The Plank Firm Luxe is a premium mattress offering unparalleled firm support but with the added benefits of a hybrid mattress.
Benefits of a Firm Mattress
Spinal Alignment
Plank supports the natural curve of your spine, promoting proper alignment. This helps reduce back and neck pain, offering enhanced comfort.
Reduced Pressure on Joints
Plank’s firm support reduces pressure on joints by preventing excessive sinking and pressure point buildup. Ideal for those with joint pain, arthritis, or chronic back issues.
Back Pain Relief
The Plank’s ultra-flat surface promotes proper spinal alignment, helping alleviate discomfort. Compared to softer options, its firm support provides better long-term relief for those suffering from chronic back pain.
Improved Sleep Quality
Plank reduces tossing and turning, promoting uninterrupted sleep. This is especially beneficial for those with sleep disorders like insomnia.
Durability and Longevity
Firm mattresses generally last longer than softer ones due to their durable construction. The high-density foam and robust coils in the Plank Hybrid enhance its lifespan, offering lasting support.
Better Blood Circulation
The Plank’s ultra-firm feel ensures better circulation, unlike softer mattresses that can cause pressure points and disrupt blood flow through sinkage.
Factors to Consider When Choosing a Firm Mattress
When selecting a firm mattress, focus on one that provides strong support, particularly for your lower back and hips, as these areas are more prone to discomfort. Your weight, height, and sleep position play a role in determining the right support level. For back and stomach sleepers, a firm mattress ensures the lower back doesn’t sink, helping to keep the spine and hips aligned and reducing back pain.
However, for side sleepers, a firm mattress may create pressure points on the shoulders and hips, which bear more weight in this position. A softer mattress can alleviate this pressure, offering better comfort and weight distribution.
Temperature regulation is another key consideration. Some mattresses, particularly those with memory foam, may trap heat, causing you to sleep hot. Look for mattresses with breathable materials and cooling features to maintain an ideal sleep temperature.
For those sharing a bed, motion isolation and strong edge support are crucial to minimize disturbances from movements.
The materials used in your mattress also matter. Memory foam offers excellent contouring and pressure relief, while latex provides durability and responsiveness. Hybrid mattresses combine foam and coils for the best of both worlds—support and comfort.
Finally, consider mattresses with third-party certifications or endorsements, such as those from The American Chiropractic Association (ACA), which supports spinal health and wellness.
Why Plank is Right for You
Plank mattresses are specifically designed for those who prioritize back health and posture, offering an ultra-firm, flippable surface inspired by minimalist sleep traditions. With dual comfort options, the mattress features a standard firm side and an ultra-firm side, allowing users to customize their sleep experience. The design is engineered to reduce pressure on the circulatory system, promoting better blood flow and providing exceptional lower back support, which can lead to deeper, more oxygen-rich sleep.
Plank also offers a 120-night sleep trial, ensuring that customers can test the mattress and determine if it’s the right fit. If it’s not, the company provides assistance with returns.
For those seeking extra-firm support, Plank offers two standout options:
Plank Firm
The ACA-endorsed Plank Firm is an all-foam mattress offering superior extra-firm support. Featuring high-density foam layers, it provides long-lasting comfort while soothing pressure points on the hips and shoulders. The mattress is flippable, giving users the choice between ultra-firm and medium-firm options, and the reversible design helps enhance its durability. An optional Glaciotex™ Cooling Cover can be added to both sides to regulate temperature, preventing overheating during sleep. The comfort layers are specifically designed to relieve pressure and contour to the body for a restorative night’s sleep.
Plank Firm Luxe
The Plank Firm Luxe, also ACA-endorsed, is a hybrid mattress that has been proven to reduce spinal stress and improve lumbar support. With a flippable design similar to the Plank Firm, the Luxe model features individually encased coils that provide targeted support and superior motion isolation. As the firmest hybrid mattress on the market, the Plank Firm Luxe offers unmatched support for back pain relief. The optional Glaciotex™ Cooling Cover ensures a comfortable sleeping temperature, making it an ideal choice for those seeking optimal spinal alignment and comfort throughout the night.
