14 inch CoolNest

I got the 14 inch and as I'm looking through the reviews, I don't see anyone that got the same mattress as me. Everyone mattress looks way different than the one that I purchased, which is the sweetnight coolnest i'm gonna let it flush up it says 24 hours to 72 hours so I'll give it about two days so far it's very heavy amazing quality I did get medium soft it does seem a little more softer than I expected but again it is not done fluffing but I can't wait to sleep on it

Very comfortable. I recommend you let it set the full 3 days to let i completely expand. I did and it met the fill 16 inches that was guaranteed. It is very comfortable to sleep on with good support. Maintains great support. I would recommend this mattress. Great price for the product.

Easy on the wallet and back

Easy on the wallet and back. I've slept in these for over a year now. Just got my second for a spare bedroom. These truly are amazing. I was a Casper fan for years, but then switched to these. Never going back. Broke 3 vertebra in my back years ago and am sensitive to mattresses. The 12” thick bliss is just incredible. Perfect combination of support and comfort and heat dissipation.
