  • Good night sleep
Size: King Style: 14 Inch
Comfortable and just the right amount of support. It expanded quickly & We were able to sleep on the mattress that evening. Quality 9/10, due to the edges being a little "soft" but that doesn't make the mattress any less comfortable.

  • Amazing
Size: King Style: 14 Inch
The most most comfortable bed I’ve ever bought. The quality is unmatched . It didn’t have a smell and the firmness was just what I needed. Ease to set up and the 14” is the perfect thickness.

  • Comfortable and perfect for growing kids
This mattress has great support, a soft top layer, and feels much more expensive than it is. It expanded quickly, has strong edge support, and sleeps cool. I got this for my grandson and it’s perfect for him — he loves it and sleeps great on it.

I was surprised that this mattress is actually pretty comfortable. It is a bit firm for my preference but still pretty nice.

  • Great mattress for affordable price
Size: King Style: 14 Inch
I am really satisfied with this purchase! After moving, purchasing a really expensive wasn’t on my priority list so after researching, I settled with this mattress! I’m really pleased for the amount I paid! I’m hoping this mattress will last me at least 3 years!
