Features

  • 100% FIBERGLASS-FREE & SAFE Sleep soundly knowing your mattress is completely free of fiberglass. We strictly use CertiPUR-US certified foams and a non-toxic fire-retardant layer. This ensures a safe, healthy sleep environment for your family without the risk of skin irritation or indoor pollution common in budget beds.
  • COOLING TENCEL & WAFFLE KNIT Designed for hot sleepers. Our premium Tencel cover wicks moisture faster than standard polyester, while the unique Waffle Knit sides maximize airflow channels. This breathable combination actively regulates temperature to keep you cool and dry throughout the night.
  • HYBRID DESIGN WITH TARGETED ZONED SUPPORT Experience the dual benefits of adaptive gel memory foam for pressure distribution and individual pocket springs for robust structure. Our precision-engineered zoned support system specifically reinforces the lumbar and hip areas while cradling the shoulders. This active spinal alignment prevents the "sinking" feeling and promotes proper posture all night, making it ideal for back, side, and stomach sleepers to wake up feeling recharged.
  • REINFORCED EDGES & MOTION ISOLATION Maximize your sleep space. We reinforced the perimeter coils to prevent edge sagging, giving you stable support when sitting or sleeping near the edge. Plus, the independently wrapped springs isolate movement, so you stay asleep even if your partner tosses and turns.
  • BED IN A BOX CONVENIENCE Expertly compressed and rolled for easy delivery through narrow hallways and staircases. Fits all standard frames (box spring, slatted, platform). Simply unbox, unroll, and allow 24-72 hours for the mattress to fully expand to its original plush shape.

  • Satisfied for now; minimal edge support
Size: Queen Style: 14 Inch
So this is my first time buying a mattress online, and buying one that’s rolled up in a box. I previously had a beautyrest recharge mattress for 12 years and it was perfect until the last 12 months. I was waking up with shoulder and hip pain. So this mattress arrived Thursday afternoon and I let it inflate until Saturday morning. It’s pretty firm and supportive since I’m a heavy set side sleeper. My only problem is there very minimal edge support. I will update my review after a month or so. ... show more

  • Great mattress and price.
Size: Queen Style: 14 Inch
First time trying a hybrid mattress and I’m impressed! It is comfortable, I feel like it’s a bit more on the softer side rather than medium firm. The price was great—really happy with it!

  • Wouldn’t buy again; ends never came up
Size: Twin Style: 12 Inch
The mattress came with a heavy plastic over another interior wrap all rolled into a box. I barely opened the outer wrapping (didn’t cut anything) and it basically exploded inside my room knocking things over and damaging my wall. The ends never came up/inflated so it slopes greatly at each end so I had to put some padding to raise up the end where my head/pillows go otherwise my head is going downhill. Edge support isn’t very good on sides and non-existent on the short ends. It’s quite firm and I was hoping for a more plush uppermost surface. I’m gonna have to buy a topper to be able to tolerate it. ... show more

  • So relieved there's no fiberglass in this.
Size: Twin Style: 12 Inch
I went down a rabbit hole online about fiberglass in cheap beds ruining people's homes and completely freaked out. Bought this 12-inch hybrid specifically because it clearly stated fiberglass-free. Checked the tags immediately—no glass, just safe fire-resistant materials. We let it air out for two days (honestly there wasn't much of a chemical smell anyway). My kid sleeps on it now and I finally have peace of mind. ... show more
