Awesome bed, Firm, Cali-King, Big Man Approved!
Ordered at Cali King, firm bed. I am 6’8” 270lbs and this is truly a FIRM bed. My girl is 5’7” 120lbs and she absolutely loves it. No more leg pain she was experiencing which is a great thing. We have owned the bed for a month now and it is awesome. I honestly don’t know for quality and money you can bet this deal for $337. If you don’t buy it, you’re getting ripped off.

Good buy!
Pleasantly surprised! I got this for my teen who is about 180lbs and he loves it. We've tried box mattresses before and had to return them due to him sinking straight through. This one puffed up within a couple of hours, didn't have a smell, and even I can't feel the springs when I lay on it (150lbs and super sensitive). I don't know how long it will last but it will be too short for him soon anyway. Too be honest, I will probably get another one of these in a larger size. Great value!

Great mattress- softer edge than expected
Color: Grey
Size: Queen (U.S. Standard)
Set name: 18" Medium
Very happy with my new mattress. Got the massive 18 inch queen, and I feel like 18 in may be a bit short- seems closer to 19.5. Its absolutely decadent. The only real draw back is the edge support is a bit lacking. Not roll of the bed and land on the floor lacking, but there is more than just a little dip when you're sitting on the edge. Overall, I'd definitely reccomend- but with a disclaimer about the edge.

Stable and comfortable!
I was skeptical about buying this for my autistic 7 year old, he's a jumper. But this mattress is perfect! The foam absorbs the shock from him jumping and we can't hear it through the walls like we could with a traditional mattresses. The only downside I would say is the corners didn't completely puff up like the rest of the mattress, but other than that I have no complaints!

Wow, buy it! Better than my brand name mattress.
I was skeptical about buying a mattress in a box and after comparing different brands I picked DIFAME and I was impressed. The first time I used it I woke up with no back or hips pain. It's amazing!!! I would buying it again.
