Very soft and the size fits as expected. It’s pretty thick so I had to buy sheets with the deep pockets. Quality wise I would say I can hear the springs on the inside so it’s a little cheap but I mean the price is cheap too so can’t complain. Support wise I would say is good as a 230lb person.

Very comfortable. I love it. Firm , i ordered a full size mattress and it works perfectly for my daughter’s room. It’s easy to move around and no sinking. It supports a lot. Great size.

This mattress is literally the softest mattress I’ve ever had really good quality came fast was in a box. I was a little skeptical until I opened it, and it was huge and thick and full and soft and amazing.

Was skeptical about a mattress off Amazon honestly but very surprised with how nice and comfy it is. It’s a firm mattress and worth the money! Popped up within a day not even honestly. Definitely recommend !

I was so scared to buy a mattress online but I really needed one so I took my time to read all the reviews and 95% of them were correct. I live on a tight budget being disabled and needed something affordable and comfy. I absolutely love this mattress. It goes above and beyond what I expected. I highly recommend it and the price is worth it. It's day 2 and it feels great. Finally a good nights sleep.

I ordered the 12 inch king size and love it! Right when I cut the vacuumed sealed plastic it immediately filled with air and looked just like the picture in a matter of seconds. The sides are 12inches making it a perfect height when on the frame. There are no sunken corners or uneven spots. It fit the frame and mattress cover perfectly. I love the soft but firm feeling on my back I had instant relief when I lied down. There is no weird smell and no spots. Also, I would like to add that when getting ready to take the plastic off, lay it on the bed frame or floor wherever you are putting it because the king is definitely big and heavy. Highly recommend.

DO NOT I repeat DO NOT purchase this mattress!!!!!!! I just moved into my apartment, bought this mattress, and it leaked fiberglass all over my room and I had to throw EVERYTHING AWAY and move out. The seller LIED and said there is nothing fiberglass related in the mattress but this is untrue, THERE IS! Myself, my friend, AND girlfriend all had horrible skin reactions, coughing, mucus, sneezing, and my lungs are STILL recovering after 2 weeks. Mind you I was only exposed for 3 DAYS!!!!The mattress is also uncomfortable, flimsy, and SUPER BAD QUALITY. PROTECT YOURSELF AND YOUR FAMILIES AND LOVED ONES DO NOT GET THIS MATTRESS!!!!!!!!!
