Perfect size for my husband and I! Extremely comfortable despite the reviews! Not too soft and not too firm either, it provides the perfect support we wanted. Was just perfect! Color also added another great touch to it!

This purchase was fantastic. It’s firm yet comfortable, exactly what I needed. There’s no noise, and it’s of good quality. I decided to let mine expand for about three days in a spare room before using it. I didn’t know I had to do that, but since it was vacuum-sealed, I figured I’d do it on my own.

    • HORRIBLE SMELL!!
Do NOT buy this mattress unless you want your entire room to smell bad for days. It’s been 4 days now & I don’t even want to go in my room it smells so bad. Can’t tell you about how it feels cause I won’t lay on it due to the smell. Probably gonna take it straight to the dump.

    • Plish!
I’m glad I didn’t get 14 inch. This one is high and comfortable. If I get any bigger I would need a ladder to get in bed.

    • It fits my bed frame! Yay!
So far this has been a great mattress. Not too cold, not too warm. Not too hard, not too soft.
