  • Overall Good mattress, could be better
Size: Twin XL Style: 14 inch Grey
I've had this bed for a few weeks. I ordered the 18-inch; I could've sized down, but it was not necessary. Because of the thickness, it is hard to find sheets that fit. It is on the firm side, which is great for some sleepers. I do wish it came with more cushion to make sleeping on my side more comfortable. Installation was super smooth, I laid it on the frame and blew it up instantly. No weird smells, and it didn't take long to completely inflate. ... show more

  • Mattress
Size: Twin XL Style: 12 inch Grey&White
Bought this mattress for my 91 year old mother. Rest is very important for her so I bought this mattress to see if she could get better rest. She said she likes it. I matched the mattress with an adjustable frame too. The cost was very reasonable and the mattress seem to be well built. Comes in a compressed state so opening the box is kind of fun. Make sure you have room to open. ... show more
