    • Was struggling with an old spring mattress for too long
Style: 12 inch Blue Size: Full
Comfy, firm, thick, removable cover, great delivery, and affordable.

    • Love it
Style: 10 inch Firm Grey Size: Queen
I have degenerative disc pinched nerves and sacrolitis in areas of my spine. Lumbar being the worst. This mattress though, I do not wake up with burning pain multiple times through the night my hands aren't numb constantly. Definitely worth it considering I spent 110$ more on a hybrid and it caused a lot of pain. Very firm. When you move from your spot there is very little sinkage left where you were! The sides don't give if you tend to get on the edge of it! I've been sleeping so well this last week and a half! ... show more

    • Not true to size but affordable
Style: 10 inch Grey Size: Queen
The media could not be loaded. True Medium firm feeling, true Queen size 80x60, love the washable cover it has a double zipper for easy access. Only problem is that it did not expand to the full 10 inches i ordered, it’s roughly 9.5 but other than that it is very affordable and serves it’s purpose.

    • Extremely disappointed
Style: 8 inch Blue Size: Queen
I was really optimistic reading the reviews but after giving this mattress a few weeks, I’m truly upset that this mattress turned out to actually be so uncomfortable I may as well be sleeping on my old mattress. It’s WAY too soft to be considered medium firm. If you’re looking for a mattress to help with your back/hip/neck pains, this is NOT it. I literally wake up sore every day because this mattress offers so little support. I tried to contact Amazon to get a refund so I can at least get a mattress topper to help compensate for the lack of support, but they said that the most they could offer for a mattress I paid $170 for is $15-20 which was incredibly insulting. They claimed that the mattress has to be returned but I am not able to get this mattress down flights of stairs by myself; they also offered to have people come inside to get it which wouldn’t work because I travel often for work and would not be home. Plus I just don’t want dirty shoes in my room. I usually don’t bother writing reviews unless something is REALLY good or REALLY bad and unfortunately this whole experience with this mattress is the latter. ... show more

The mattress comes smushed into a box for easier transportation and does take about 24+hrs to fluff itself. The mattress is very comfortable…but, the 12” thickness that is advertised here is actually about 10.5” , realistically. I have included a picture above. The box did say 12F which I assume is 12” Full mattress and that description is correct to what I ordered. ... show more

    • Height and comfort
Style: 10 inch Blue Size: Queen
It says 10” it expanded to 8”. I tried to return it but decided not to because I got Covid and so did my son and I did not think it was safe or considerate to others to return something from a Covid infected household. Oddly though when I called Amazon customer service and told them it was not expanding and therefore it is not comfortable or supportive at 8” and I wanted to return it they said sure no problem. I did tell them I just tested positive for Covid and my son so I wasn’t sure if I should return it at that point. They were like no it’s okay you can still return it. ... show more
