Im in bed rubbing my ankles together like a cricket as i type this. This bed is phenomenal. Mind you I got this after having slept on pure memory foam for the last decade. This bed helped me understand the difference and importance of a good mattress. It sits tall and is firm-- its such an improvement my dogs hopped on and fell asleep within seconds. It provides great support on the joints. I got it at a low price due to a great sale and no regrets. My boyfriend set it up and can attest to the power of the mattress as it flips out but if you just maneuver it well with anticipation youll be fine.

Great quality mattress even though I was sent the wrong size I set it up in are guest bedroom, salt, and mattress would be too firm by far. The best mattress I’ve ever had the company got the situation fixed for me. Hopefully if it ever happens to someone else it’s the same for them.

Ok, I have problems with my lower back, 60YO electrician, 200lbs 5 10, we had a $490 Sealey and it said firm but felt medium, I couldn’t sleep on it. For $219 this mattess arrived rolled up inside a box, wrapped in plastic. We installed it in a travel trailer, set on the bed and slid the box off. They include a plastic gut knife, my wife said letter opener, I hunt so it’s a plastic gut knife. Slide across gently and the plastic unrolls, a tiny hole allowed air to rush it, it was actually cool, how fun! Within an hour I laid on it and immediately noted that extra firm was spot on. It’s soft but very supportive and firm on shoulders and hips, on my back and stomach I lay flat and my back feels a lot better that bending like a banana backwards. If anything it’s good looking, didn’t smell bad, is fairly light compared to traditional or memory foam of equivalent thickness., and we both tried and cannot feel springs. Great value, money back guarantee, free shipping, a paltry $219.00 for a queen that offers restful sleep. Longevity isn’t the issue to me unless it’s a grand I’m spending, I recommend trying this mattress.

Slept GREAT last night, needed a very firm mattress for my back and hip pain. Very satisfied! Puffed right up too you don’t have to wait long at all for it to puff up. Good quality, we will see how it holds up and lasts!

This is honestly a good mattress. I find it very comfortable and for the price or less that $350 it’s a great price for the mattress. I let mine setup and rise for 3-4 hours and had no issues with it. All the little humps were gone within a day or two. When you open it make sure it’s about where you are putting it because it expands pretty fast and it’s easier to move when it’s vacuum sealed
