  • The bed is too soft
This bed is simply too soft. I don't think it should be rated as a firm mattress.

  • 24 hours review
24 hours after opening, the mattress is presumably still expanding. Will update again at 48 hours.

  • Edge support is nonexistent
I was hoping that this would be a very high-quality mattress. There isn’t a very strong smell when unrolling it, which is great however, the Support is a little bit softer than I expected and there is virtually no edge support. I’m kind of disappointed about that.

  • Not firm
Mattress is not firm!! Not even close. Might be medium at best. Edges sag despite what description says. Very disappointed as I compared many different mattress before finally choosing this one. Did not notice any back or hip pain relief.

  • King mattress is very nice
Well packaged, opened it up and it fluffed up quickly, slept on it that night and had a nice sleep. Glad I took the chance on this.

  • Too soft
It’s not firm like what it’s mentioned. I sink down. My back feels pain every morning.
