  • Great buy
Extremely comfortable grateful for the price

  • Amazing buy
This bed has made a major adjustment for my sleeping. The last mattress we had was ok but I slept maybe four hours and would wake up sore. After two years we got this and I wake up feeling great and sleeping 7 hours easy!

Have slept on it one night and it felt great! Firmness is just right! Quality seems good!

  • Sleeping on a rock
Literally hard as a rock. I think the ground might actually be softer.

  • Decent
My boyfriend hates it, says it’s super stiff and hard. I will admit it is harder than I thought it would be but for my back issues it’s helpful. I feel this is a decent mattress for the price.
