went from firm to plush and my back feels better, mattress arrived before the base so it had a few days to expand completely very satisfied

    • Good quality, fast delivery
Color: Onyx Size: Twin Style: 8" Thin
We were reluctant to buy without trying, but gave it a shot based on the great price. Very glad we did. It arrived quickly and expanded as soon as we opened it. We had it on the bed in a matter of minutes. Had heard some complaints about other foam mattresses needing to air out, but this one had no odor beyond the typical new mattress smell. We are using this on a set of twin bunks and it seems to work fine on slats, at least for kids and lighter weight adults. We got a traditional foam and spring Sealy from a local mattress store for the second bed because we wanted some versatility, but it's hard to beat the ease and comfort of this mattress for the price. I'm not sure how anyone would go about returning this if they didn't like it -- it's very compressed and tightly rolled and I don't think it would be easy to recompress it by hand to get it back in its box. An unexpected benefit is that it's much less bouncy than a traditional coil mattress, so our kid does less crazy jumping. ... show more

Color: Onyx Size: Twin Style: 8"
This mattress is great. Comfortable, durable, but yes firm. I personally love a firm mattress so no complaints here. Both my kids sleep on these and I've never heard a complaint. Had one used daily since 2021.

    • Comfy but HOT *New Update*
Update: October 2019. It’s been 8 mos since purchasing this mattress. Just wanted to update on how it is holding up. The mattress remains as firm as it was immediately after purchase. There are no dips or worn spots in the areas my husband and I sleep in. We rotate the mattress every other time we change the sheets. So, maybe twice a month. My husband is 6’ and about 220lbs. I’m 5’6” and about 150lbs. He is a side and back sleeper with arthritis from several old back, shoulder, and hip injuries from his military career. I am a stomach and side sleeper with arthritis in my back and hips from years of riding and showing horses. The support remains amazing. The overheating problem was resolved when we switched back to our goosedown duvet instead of the synthetic comforter we were using. I guess it just breathes better. Overall, we are so pleased with this mattress that we’re starting to convert the other 3 children’s beds to these mattresses. We’ve already switched the infant to Sealy’s foam crib mattress. No crinkling to wake her up. She sleeps like a rock. If or when this mattress wears out, we’re definitely buying another one to replace it. This has to be the best mattress we’ve ever bought. Highly recommend. The mattress arrived in perfect condition. It expanded quickly. Definitely a Medium Firm- Firm support level. I’m 38 weeks pregnant and it is very comfortable for my back, hips, and supports my stomach well while laying on my sides. This mattrress sleeps so unbelievably hot though. I thought it might be a pregnancy thing but my husband confirms. Our teenage son also fell asleep in our bed reading the other night while I was watching tv and woke up in a full sweat too. I’m thinking of adding a gel mattress topper to help cool it down and get us through the summer. We’re in the southeast on the coast of SC and I’m not going to make it through summer with this mattress like it is. 5 stars for awesome support comfort and quality. But I had to take one away for the misery of waking up dripping in sweat every night. ... show more

    • Great find!
Color: Onyx Size: Twin Style: 8" Thin
I’ve been looking for a perfect mattress that’s not not too soft or too hard. After searching several department stored, I decided to give this a try. The feel is perfect at a price 1/3 of what the store offered, and free delivery with Prime.

    • One Of The BEST Investments For Better Sleep I Have Made
Color: Onyx Size: Full Style: 8" Thin
I did not review this right away as I wanted to wait until I had actually slept on it for a month or so. Now that it has been about a month and a half I will say that this is one of the best investments for sleep comfort that I have ever made. I have had lower back issues along with left shoulder problem since my early 20s (I am now just south of 70). I have read about mattresses with memory foam tops for several years now and thought someday. So back in February I saw Sealy was having sales on their mattresses and found this particular one on Amazon. I will say now that I have slept on it for almost two months that I would say it is worth the non-sale price for the better sleep it has provided me in this past 6-7 weeks. The mattress was packed into a box that when you look at it you wonder how in the world can it contain something as large as an 8 inch mattress but if you follow the easy directions and let it sit for at least 24 hours, you will see that it does. It does have some weight to it so be sure to take the plastic off when you have it laying on the bed frame where you are placing it. In the past 6-7 weeks I have experienced some of the best sleeping hours experienced in many years (really cannot remember how long it has been). I fall asleep faster, do not awaken that often and my lower back pain is probably about 2/3 improved over what it was previously. My left shoulder issue is also improved. While, at my age, I know these problems are never going to be fully resolved, this amount of improvement is extremely welcome. The only problem that I can note about this mattress is that I really do not want to get out of bed in the morning because it is so comfortable. ... show more

    • LOVE IT!

Review Image by StacyLee StacyLee
Night 3 of my son (almost 3yo) sleeping in his new big boy bed. He really loves it. He fells asleep faster and It is REALLY comfy. the picture was right off the box and was already at 7,5inch….After 24h the corner was “formed”. It’s more of a medium/ firm mattress for adults and firm mattress for toddler. My son sleeps through the night and he keeps saying that his bed is comfy and he is happy of his new bed! So it’s a huge WIN for my husband and I. OVERALL it’s a 5 ⭐️for us! Fit perfectly his IKEA Neiden bed frame. ... show more
