Features

  • 365-NIGHT TRIAL & LIFETIME CARE If it isnt the right fit at any point within 365 nights, we arrange a no-hassle return or exchange and handle all logistics, including donation pickup. And with lifetime service support, you can contact us years later for guidance, inspection, or resolution.
  • INSTANT FRESH & CONTOURED COMFORT Sleepmaxs patented fusion Memory Foam provides cool relief and responsive contouring for a secure, pressure-reducing cradle. Cooling gel helps lower surface temperature, copper supports healthy circulation, and bamboo charcoal with green tea naturally minimize odors to maintain all-night freshness.
  • 3 PRESSURE RELIEF The Sleepmax Hive system uses independently adapting hexagonal springs modules to reduce peak pressure by up to 3 times versus standard hybrids. Its geometry transfers load smoothly across shoulders, hips, and the lower back, supporting balanced circulation and easier next-day recovery.
  • FULL-SURFACE ADAPTIVE SUPPORT Instead of limited zoned layouts, our mattress uses a multi-point honeycomb spring matrix with hundreds of individual support nodes spread across the entire surface. This uniform grid adapts instantly to any body shape or height, delivering consistent lift and alignment for side, back, and stomach sleepers alike.
  • CLEAN, NON-TOXIC BUILD Crafted from carefully selected, certified materials and produced in-house through vertically integrated manufacturing. Backed by over 40 years of mattress-making expertise, every component is engineered under strict quality control to ensure a safe, durable, and responsibly made sleep environment designed to last.

Description

A multi-point honeycomb system adapts in real time, delivering full-body support, balanced pressure distribution, and precise spinal alignment. A cool-to-the-touch fabric stays breathable and effective, delivering consistent cooling comfort and temperature balance—even under sheets. A Fusion memory foam layer contours gently to your body, delivering hugging support, pressure relief, and a secure, comforting sleep feel. Is this mattress suitable for side, back, and stomach sleepers? Yes. Every size and thickness uses Sleepmax’s exclusive hexagonal coil matrix, paired with a high-density comfort layer to deliver adaptive, balanced support for side, back, and stomach sleepers. How is this better than zoned mattresses? Zoned mattresses rely on fixed support areas that may not fit every body. Sleepmax instead uses hundreds of adaptive support points that respond to pressure, adjusting to different body shapes and sleep positions for consistent alignment and relief. How does the 365-night home trial work? Your 365-night trial begins when your order is placed. If any quality-related issue occurs within one year, simply let our support team know. We’ll assist you through the process and make sure you’re fully supported. Can this mattress help with back or joint pain? By distributing weight evenly and maintaining natural spinal alignment, Sleepmax helps reduce pressure buildup that can contribute to back and joint discomfort. Is this mattress good for different body types and weights? Yes. The adaptive support structure responds to pressure point by point, making it suitable for all body shapes, including heavier builds and athletic frames. 365-NIGHT TRIAL & LIFETIME SERVICE Sleepmax's commitment knows no bounds. • Tested Trust All products carry CertiPUR-US certification (free from ozone depleters/PBDEs), while OEKO-TEX Standard 100 fabrics ensure skin-safe materials. • Precision Production 132-point quality checks result in industry-leading defect rates below 0.8% across all product lines. Our raw materials undergo internal design and manufacturing, enabling efficient cost reduction and quality control.

  • Firm mattress
Color: Grey Size: Queen Set name: Omnifit 13''
This mattress is very firm. We were expecting it to be more medium firm. If that makes any sense. My uncle has stage IV prostate cancer that spread to his spine. Originally we were told a firmish mattress would be better for him, but this one is too firm and not enough support on the sides. We reached out to the seller and they were more than accommodating. We decided to keep the mattress, but they offered free pickup and return. No hassle either. I cannot give enough compliments to the seller. Because of how easy they were to work with, we will use them in the future. For now, we bought a Tempur-Pedic mattress topper to soften the bed. It worked perfectly. ... show more

  • Very comfortable
Color: Grey Size: Queen Set name: Omnifit 14''
I was wary buying a boxed mattress but after paying twice as much for our last one that fell apart in less than two years I thought I’d take the chance based on the reviews. My wife and I absolutely love this mattress, I’ve haven’t had a mattress this comfortable ever. It’s almost too good to be true so I bought the 3 year protection plan just in case. It’s been about a week and we’ve never slept better. ... show more

  • Best for its price
Color: Grey Size: Queen Set name: Omnifit 13''
This is just firm enough so laying in any position doesn’t feel like I’m laying on concrete It feels very thick with a hint of plushness Seems very durable after putting it into them 6-sided covers My sleep has never been so good. I work weird shifts on different days and this lets me wake up earlier than I plan to and my body does not complain For how much it costs, it is way ahead of the competitors; cheap and high quality It feels nice and cold to the touch even after adding a protective layer ... show more

  • Should be labeled firm medium
Overall transaction was great and came sooner than expected. I would say the mattress is between medium and firm not medium but overall a great purchase

  • Hip Pain? Buy this!
Color: Grey Size: Queen Set name: Omnifit 14''
This is a hell of a mattress. It is incredibly solid, sturdy abd very comfortable. I was squeamish about buying one of these bed in a box things, but I am so glas I did. I think its well worth the price and the setup is easy. Its heavy as hell tho, obviously. It helps my hip pain quite a bit, and I've been dealing with that for several years. This is the best investment I've made in a long while. ... show more
