I could not believe the quality of this mattress and overall feel and firmness for its value. I had a mattress that cost more than this one and it was unable to match it in its performance and feel and durability. That other mattress was hurting my back and not offering me the support that this mattress offers me at half the price. If you're looking for a firm mattress, one that is not going to break your back Just because it says it's firm. This is a firm but yet supporting mattress that even when you sit on the edge it doesn't fold or crumple all the way down it bends it flexes and it moves but still holds you up without you going or being flat on the edge of this mattress. There's a lot of mattresses that don't hold up when it comes to the corners or the edge of the bed when you go to sit on it. This bed is not one of those. It will support you and hold you up. Don't be afraid because people have said it's a firm firm mattress It is firm but it is very supporting so it's not a firm where it's going to break your back because it doesn't move. It does move, yet it holds its regility and bounces back to its original state. Free from mattress it's very comfortable very supportive feels good looks good and the price is truly incredible for all that you're getting.

So pleased. I am going to point out all the basics about this purchase. Delivered on time. No smell when opened. Thickness almost inflated to 14 inches upon opening. We let it rest for time suggested before sleeping on it despite it being at 14 inches all the way around. Medium firm is exactly right. Firm with right amount of give. Bed absolutely feels cool to the touch. Best sleep I have had in quite a long time. No night sweats last two nights. Set up was easy. Just follow the directions. For a king size would suggest two people to set up. Sleep wise I have no hip pain and my neck stays straight with pillow. I never felt my hubby move so motion isolation works. We have only slept on this two times so I will update again in a month. But not disappointed. Disappointment is my last mattress from a mattress store and the poor quality of sleep with a much higher price tag. I hope this helps someone. Hubby, dog and I are pleased with the purchase so far. Worth the price even for first two nights of actual sleep, but we do hope to get many nights of rest from it. Oh forgot to mention the size was accurate for a standard king. So no issues there. Update: 12/09/25 Still loving it. Comfy and still terrific sleep. No sagging so far. No night sweats. Cooling works.

I’m really not sure why people still go to mattress stores and pay thousands of dollars when you could buy a mattress like this for just a few hundred dollars. Totally worth the price. Very comfortable great quality.

Overall I really comfortable bed with a good amount of edge support. It was super easy to set up. Let the bed inflate for 24-48 hours before sleeping on it. Honestly for the price you can’t go wrong. I highly recommend buying this vs big brand store mattress for quadruple the price.

Great quality for the amount of money. Needed a new mattress but didn’t want to spend thousands. By far well worth the money. I have chronic back pain and it’s firm but comfortable.

Only had this mattress for a short time, but so far I am highly pleased! Was always waking up with a sore lower back and unable to sleep for more than six hours. I have paired this mattress with an adjustable base also bought on Amazon and I’m having the best sleep in years! Waking up with no back pain or stiffness.(sounds too good to be true, but it is!) not sure about longevity, but so far would highly recommend this mattress. One of the top reasons for purchasing this was it was one of the few mattresses that allowed you to choose a firm option. It is firm enough without being too hard. edge is a little soft when sitting on the side of the bed, but I found that is the way with most hybrid./memory foam mattresses. Does it affect sleep quality at all though.

Love the mattress. Extra firm, as described. Back is feeling great and I'm sleeping the best in a long time.
