  • Description is Accurate!
Style: 12" Size: California King
Inflated from packaging rather quickly had no bad odor to it and is medium, firm just like package says. Overall Solid product would recommend to any buyers on a budget

  • Very supportive mattress
Style: 12" Size: California King
The mattress is very heavy, 110 pounds. I think it is a firm mattress. We've been sleeping on foam mattresses for years, I like the springs in the mattress. It feels more supportive and like it will last longer. If you are looking for a bed you will sink into when you lay down, this is not the bed. But in the morning you will feel much better than you have been when you get up. ... show more

  • Not medium firm and no edge support
Style: 10" Size: California King
You get what you pay for. This mattress is like something you find in a pullout couch. I would describe this mattress as medium more on the softer side not firm at all. Not an accurate description. Not even close.
