  • Very comfortable
Size: King Style: 12 IN
First few nights are very firm but it softens out and keeps the support. Inflates quickly. Great value as I previously had a dreamlux and this is comparable.

  • King Size Memory Foam Mattress
This was a great buy on an absolute, comfortable mattress, that I put on the adjustable frame I purchased.

  • Mildew Smell
Size: Twin Style: 10 IN
It’s comfortable but definitely came with a mildew and moldy smell. Can’t even sleep on it. My allergies were out of control

  • Definitely a bit less than 6in ...
Size: Twin Style: 6 IN
The mattress is good, seems firm yet soft. No one has sat or laid on it yet since I've been leaving it to rise for 3 days. It is definitely shorter than 6inches. Closer to about 5 and like I've said, I've left it to rise without any pressure on it. That's the only downfall. Otherwise it seems decent. ... show more

  • Great Sleep!
Size: Twin Style: 10 IN
Great extra bed mattress. I got the 10 inch model. It’s the perfect size. Firmness is in the middle to firm level but has the soft top that’s like a dream. I’m a fairly big guy and it has plenty of support. Good night sleep. It’s also a great value. Well worth every penny

  • Comfy!
Size: Full Style: 5 IN
It’s super comfy and the memory foam is something I’m not used to but it’s perfect! I struggle with heat at night and this is perfect with air conditioning !

  • Super comfortable!
Size: King Style: 8 IN
This was my first time ordering a mattress online and I was pleasantly surprised! A lot of people said they had issues with it not being the thickness it states, I took the mattress protector off while it was airing out and it's actually a half inch thicker. So I suggest taking all the plastic and the protector off! It's firm, so if you want softer, a topper is suggested! I have Lymes Disease, so I have a lot of joint pain and stiffness, this mattress helped so much and I'm getting much better sleep already. Plus, I can move around throughout the day much better! ... show more
