Thank you so much for creating this extra firm mattress! It mimics the floor in terms of support, which has been a day-night difference! # of coils provides proper support, along with notable material air flow. 

I have scoliosis- spondylolithesis- disc bulge that was continuously aggravated by both Casper + Purple mattresses. 

So grateful to leave all those back problems behind + be reunited with another Beautyrest bed (my original childhood mattress brand)! 

Stood home the entire weekend I received this bed + slept! No more waking up feeling like a truck hit me! Back in action like I never left!
