  • Very comfortable mattress if you have back pain
Size: Full Style: Full
The media could not be loaded. This mattress is awesome. I really love this mattress. First time when I laid down on this mattress, the first thing that got to my mind was "I finally found the right mattress I was looking for". It has the perfect amount of firmness. Its not at all hard and not too soft. In my previous mattress, I was having lower back and neck pain issues as it was very soft. But this doesn't feel like that. I do Crossfit after work everyday in the evening and some days I get back pain through weightlifting, this mattress contribute a little to recover from that. Initially I thought 10" inch won't work for me but its the right amount of thickness for me. I don't use pillow to sleep usually and with this mattress and I don't even need one. I can't express my feelings about how happy I'm with this mattress. Just sharing my experience so that you can also benefit from it. Its worth the money and its a great quality product. You won't have any problem if you are looking for a Firm mattress. ... show more

  • Different Firm Level Big +
Size: Full Style: Full
I have never brought such a big product, mattress, from an online retail store. However, due to Covid and to promote social distancing, I have decided to give this mattress a try given the good review. Following are what I gathered: Pros (firm level) - I really like the different firm level! I am used to memory foam and have used it for nearly half a month. The mattress meets my need. Just recently, my parent came for a visit and are used to firm beds. I was glad that I was able to flip the mattress over for her. It fits her need. It’s very comfortable. Pro (light packaging) - the airless packaging was wonderful. I was able to setup the bed on my frame with minimum help. Just lay the mattress on the frame and cut open. Pro (sleep quality) - I am a light sleeper but I sometimes get an entire night of sleep from this! However, the mattress is abit pricy compare to what you could get from Costco/Sams, but, I think it is totally worth for the firmness and quality. I highly recommend this mattress. ... show more

  • Good buy
Size: Twin Style: 10 Inch
I bought this for my toddlers big girl twin bed. After unpackaging I thought there was no way this would expand to 10”, but I gave it 24-36 hours and it did. I can’t attest to longevity or back support, but I’ve lain on it for a small period of time and it felt very comfortable.

  • Did not get up to its full size and no edge support
Size: King Style: 12 Inch
The media could not be loaded. I bought this mattress based on a lot of good reviews and the fact that the description said it has good edge support. First problem is that it never inflated to its full 12 inches. The instructions say to let it sit for 72 hours and I let it sit for five days and it’s still only at 10 inches. I paid for a 12in, not 10in. Second issue is that it has zero edge support. It sinks in so bad. Third issue is that it states it is a medium firm mattress, but it’s actually plush. It sinks way too much and hurts my back, so unfortunately, I’m having to return it. ... show more

  • Very comfortable
Size: Full Style: Full
The first few nights sleeping on this bed were an adjustment because my former mattress was too firm that causing me to get low back pain. This new mattress is not so soft that it dips, but enough give for my hip and shoulder when sleeping on my side. After a week I would call this mattress the perfect combination of supporting to my body, and I do not fall into it. I feel better for the back pain; I still need more time to feel it, but so far so good. It’s so great to have an option for a comfortable mattress for good price. ... show more

  • Support & Comfort
Size: Full Style: Full
I was nervous about this mattress because although it was squishy, it was still pretty firm. I ordered it for my guest room, and thought I'd made a mistake and my guests would be sleeping on a hard mattress. This was not the case at all. My guest love it! She said it was super comfy and easy to sleep on. I didn't believe her, so I slept on it for a couple weeks. I was still unsure because I didn't sink into the bed the way I do on my mattress, but the memory foam still cradled my body. I noticed I didn't roll around as much switching sides, I could sleep in one position and be fine all night. The foam just formed around me, but also was supportive, so my hips didn't dip or cause my spine to not be level. I am really impressed by how comfortable this mattress is, and how well I sleep on it. Definitely a good purchase for the price! ... show more

  • The best Mattress ever!
Size: Full Style: Full
Because we have a baby girl last December, it is too crowded to sleep in our current bed. We were thinking of getting a new bed, but ended up buying this mattress instead. At first, this mattress was recommended by a friend, who’s been using this mattress for a year. We didn’t expect the level of comfy. Now, “wow, so comfy”! Personally I don’t like soft mattress, because I feel I’m sinking into the mattes, and tired when wake up the next day. This mattress is firm enough while I sleep in. It’s also perfect for a back sleeper like me. It says it takes 72 hours for the mattress to return to its full shape, but you can totally sleep in after 24 hours. (We can’t wait for 72 hours😂😂😂)We put the mattress under the bed, and pull it out while using at night. ... show more
