    • Luxury comfort with a budget price tag!
Size: King Style: 12"
For those who suffer from back problems and need good support while sleeping this is the best bang for your buck! Originally purchased in 2019 for a new home because of the price point, I have since fallen in love with this mattress. It’s firmer than most but that doesn’t take away from its comfortability. You’ll sleep through the night and wake up without back pain or aches. All king size sheets fit perfectly and snug to mattress. The 12 inch thick foam will leave you feeling elevated and fill in any bed frames. There is zero noise produced and it took less than 4 hours to fully expand. 10/10 would buy again! ... show more

    • Great value for the price!
Size: Queen Style: 12"
Excellent quality for a mattress if you already have a box spring or platform bed. Way more than what I expected with it coming vacuum-shrink wrapped and rolled up and placed inside of a 12x12 box. Not heavy at all either because I drug it inside, opened it, and unwrapped it myself while my husband was at work. We had purchased a one-sided pillow top when we got married about 6 years ago with a bedroom suite brand new from Rent-A-Center, so the transition from sleeping on a mattress (even a pillow top) with coils inside of it to this memory foam mattress took a night or two to adjust to. It is a firm mattress, however it's still super soft and comfy. And surprisingly, it isn't hot which was a fear we had with pitcher a memory foam mattress. I had one in the past and it was so hot sleeping on that mattress in the summer regardless of the type of fabric the sheets was made from, but the cooling gel they placed inside this one makes all the difference in the world. Sheets that you purchase today automatically come as deep pocketed sheets unlike the standard sheets from when I was a child, so any set of standard sheets you purchase nowadays is guaranteed to fit without you having to get measurements before purchasing them for this mattress. Our previous sets fit this mattress perfectly with the 12inches of memory foam that the mattress consists of. The material this mattress is made of actually keeps your sheets from slipping or coming off, guaranteeing they do not to slip whatsoever regardless of whether they're microfiber, Jersey cotton, satin, cotton, egyptian cotton, and even silk! Pretty much fills totally out to original size in minutes even though the box says 78 hrs. No problems with ours and we've had it about a month now. It's still maintaining its form and firmness. Altho it is a firm mattress, it aides and relieves pre-existing back pain and pressure quite noticeably. Our previous mattress would have my back and my husband's back in a mess before the morning. I'd often wake up about every hour and a half due to how bad my back had gotten. However, I only wake up about once a night now and that's only because we have 3 kids and j get up and check on them during the night. Neither one of us wake up groaning in pain and dreading trying to get out of bed like we had been so since we purchased this mattress. All around exceptional quality & comfort for the price and it ships rather quickly. We had ours in less than 4 days. We absolutely love ours and are glad we made the switch from our old mattress to this one! ... show more

    • Excellent comfort at a great price
Size: Queen Style: 12"
We slept on this mattress at a short term rental and loved it, so we bought one for us. It’s much better than expensive mattresses I’ve had in the past. It’s not rock hard by any means, but it does feel supportive. Our low backs don’t ache in the morning. Happy we got to test it out first. The Amazon delivery and haul away was quick and easy. ... show more

    • Great long‑term mattress for my son — still supportive years later
Size: Full Style: 12"
I bought this mattress for my son back on February 18, 2020, and it has held up really well over the years. I wanted something affordable, supportive, and easy to set up, and this one checked all the boxes. It expanded fully within a day and didn’t have a strong chemical smell, which I appreciated since it was going in his room. My son has slept on it every night for years, and it’s still comfortable with no major sagging or dips. The memory foam gives good support without feeling too firm, and it helps with pressure relief. It’s also fiberglass‑free, which was important to me when choosing a foam mattress. Pros: • Comfortable and supportive for long‑term use • No sagging even after years of nightly sleep • Easy setup right out of the box • Great pressure relief • Fiberglass‑free • Good value for the price Cons: • Can sleep a little warm without a cooling topper • Edge support isn’t as firm as a hybrid mattress Would I buy it again: Yes — it’s been a reliable, comfortable mattress for my son and has lasted much longer than expected. ... show more
