So worth the price
Size: King (U.S. Standard)
Set name: Premium Than Memory Foam
This 10-inch gel core mattress has exceeded my expectations. It offers a great balance of comfort and support, with gel-infused foam that helps keep the sleeping surface cool and comfortable throughout the night. The mattress contours well to the body and helps relieve pressure around the shoulders and hips. It feels supportive without being too firm, making it comfortable in a variety of sleeping positions. Motion transfer is minimal, which is a nice benefit when sharing the bed. The mattress expanded quickly after unpacking and had no odor and only took a few minutes to set. It feels durable, holds its shape well, and provides a comfortable night’s sleep. For the price, it offers excellent value, and I would recommend it to anyone looking for an affordable gel memory foam mattress.

well done
Size: Twin
Set name: Cooling 12"
I wasn't sure what to expect at this price, but this mattress ended up being a great surprise. It arrived compressed, expanded to its full size within a couple of days, and didn't have a strong odor. The memory foam feels supportive without being too firm. It cushions my shoulders and hips well, and I wake up without the stiffness I used to have with my old mattress. I also noticed that it doesn't transfer much movement, which is a nice bonus.

LIFEMENT King Premium Than Memory Foam Mattress, Great purchase
Size: King (U.S. Standard)
Set name: Premium Than Memory Foam
I bought this mattress for my parents and they are very loving it so far. They said it is the perfect balance, not too bouncy and not too firm. Unboxing and setting up were very straightforward and easy for my parents to set it up by themselves. I'm very glad that I chose this mattress for them.

Nice but not firm
Nice mattress. Comfortable but not, in my opinion, Medium firm. A bit too squishy. No odor and expanded well to full size.

Get this bed if you’re not a status-obsessed classist!
The bed is certainly soft and comfortable. At the price there really isn’t a huge plethora of other options, and as long as you don’t open it and immediately jump onto it for a nap it will expand and, at least in our experience, conform pretty perfectly. You really only have to open it and it’s ready in a few hours, really easy. No inflation necessary of course. It won’t keep you cooled off in a heat wave by itself either, so keep your fan. For reference we are a couple, one of us is 110lbs and the other just under 300lbs, and we sleep in the bed with 1-2 cats and a few stuffed animals, plus 6 pillows between us both. It fits us all wonderfully in the full queen size. I imagine it would be just fine for kids as well. It doesn’t weigh much itself.

Perfection, only Purple style mattress I could find with the gel grid
Size: Full
Set name: Premium Than Memory Foam
The only gel grid mattress I could find on Amazon that is like the purple mattress. Got it for my mom, she has severe back pain with her last bed. She sleeps sitting up and uses a cpap. This bed has been really great for her and she hasn't been in pain. Make sure you pull the feet of the bed up high enough to prevent you from sliding at night, she had to do that. To help with the sliding issues I got the mattress grip you lay down on the frame under the mattress. I bought her thick 180gsm Flannel sheets from Mellanni Bedding from their website and a thick Flannel duvet also from Amazon. Also got the clips for the sheets just in case bit haven't needed them yet. So glad we got everything, mom is pain free, no longer slipping in the night and getting quality sleep. Would reccomend and thinking about getting me this mattress also!

Great Mattress
Size: Full
Set name: Cooling 8"
I bought this mattress to upgrade my son’s bed to a bigger size. He loves it, and I’m impressed by the quality and firmness. It fits his new bed perfectly, too. The material looks and feels nice, and it’s made very well. He says that he sleeps much better on this mattress. I highly recommend this mattress!
