  • Very firm, I loved it, my wife didn't; hard to return
Size: Queen Style: 10 Inch
I'm tall and thin and suffer low back pain from sinking into a normal mattress. My parents had one of these in a spare room and after spending the night there, I was amazed at how great I felt. It's so firm you feel like you're floating on top of it rather than sinking in. I bought one to replace my $1600 Saatva. I loved it. My wife hated it and said it was like lying on a rock (somewhat true). We had to let it go and then realized that returning a compressed mattress after taking it out of the box is nearly impossible. (We ended up wandering around a traditional mattress store together to find something we could both live with.) Highly recommend if you are certain you want a really firm foam mattress. Don't recommend if you're not sure. ... show more

  • Whoever says the firm isn't firm dont know what they are talking about.
Size: Queen Style: 12 Inch Firm
I slept on this mattress for ONE night and I already know what I got. I slept on it the same night I unboxed it. But I slept on it upside down. Why? Because it was firm on the bottom so and still was memory foam so I slept on it. I have yet to sleep on the side that you are suppose to sleep on but I cant imagine it not being more supportive. I slept through the night for the first time since I started sleeping on a blow up mattress. I bought a house and then the people who wanted to move into the house I was staying in pushed me to leave faster knowing I could have stayed and told them to pound sand, I left and stayed at my fathers house for a few weeks while my settlement went through and while I dealt with a home seller who didnt want to leave. For weeks I slept on a blow up mattress and woke up multiple times a night. Last night was the first time in weeks I didnt wake up even once. Which is how I like it. Woke up fully rested and no pain. One thing I dont get about the advertisements from this company and I think they need to straighten it out.... No matter if you click on 12 inch or 12 inch firm, the materials spoken of are the same size and same materials. So, how can one be firm and one be medium firm? How is that even possible if the materials are the same? I know the mattress is firm. FIRM DOES NOT MEAN YOUR HAND CAN'T SINK IN IT!! Your hand is able to put way more pressure per square inch on the mattress than your body will. It is relative to how much YOU sink in the mattress when you lay on it. And I do not sink at all on this mattress. Those people who prefer soft plush mattresses either never had back issues or is going to have them soon enough. Firm is the only way to go. With a layer of softer material on top. Preferably some cooling foam. This mattress is excellent and I didnt even wait 72 hours. Heck I didnt wait 24 hours. I have been shot with a .38 special in the spine in 1996 so I need quality or I will be in rough shape. The mattress makes all the difference in the world. My quality of life is already lowered... But with a bad mattress it gets significantly lowered even more. But this Mattress is perfect in firmness coolness and support. I almost felt bad because I saw a 2450.00 mattress for sale for 475.00 right after a bought this. But, That was my inner salesman coming out. I would buy that mattress and resell it. This mattress is just as good if not better. What I know for sure is... its good enough for those who need quality in the firmness but also support and coolness. ... show more

  • So far so good
Size: Queen Style: 10 Inch
This came out of the box and popped up to the full size very quickly. It was for a guest room and he said it was very comfortable. there was no noticeable smell like some people have mentioned. It’s only been used two nights so far so we will see how it holds up.

  • Pleasantly Surprised
Size: Twin XL Style: 8 Inch
I was apprehensive: An 8" steel frame foundation topped by a Molblly 8 inch Gel Memory Foam Mattress couldn't possibly replace a conventional 8" inner-spring mattress with box springs. But it does. The foam mattress is firm and comfortable. Every bid as good for sleeping as the former inner-spring mattress with box springs. But there are differences: The foam mattress is lighter than an inner-spring mattress. So it slides on top of the foundation when pushed. A minor inconvenience. Also, kids jumping on the foam mattress will be disappointed. A foam mattress on a steel foundation is no substitute for a trampoline. Much less give and rebound. But for sleeping, I have no complaints. Hint: We ordered the 8" thick mattress because our mattress cover and fitted sheets were made for an 8" thick mattress. I think our sheets and mattress cover would have worked fine with the 10" thick foam mattress. ... show more

  • Firmer than thought
Size: Queen Style: 10 Inch
The mattress is very heavy and firmer than I thought, but still pretty comfy.

  • Better than expected!
This is our first gel memory foam mattress and really didn’t know what to expect but we are very happy with our purchase! We got the blue extra firm since it will only soften upon age and still provide the firmness we need. I was disappointed that the top cover doesn’t come off independently from the entire cover but chose to put a separate cover on that I can easily take off to wash. There were some black spots on the mattress upon opening but the manufacturer was quick to resolve with a credit back. All in all a great experience for us and we love our new mattress! ... show more

  • Great value
Size: Queen Style: 10 Inch
A little firmer than I thought it would be but very comfortable. If you like plush you might want to get a mattress pad. Even still, I'd buy it again.
