Excellent firm mattress

My sister seems to be comfortable and sleeps well through the night. No more saggy mattress she wakes up with a smile on her face.

Sister bed

Not too firm, not too soft, just right! In love with my new mattress. Highly recommend. It makes a difference!

Perfect Sleep

2 1/2 months in and my husband and I still haven’t adjusted to this mattress. It does not have a cooling effect whatsoever, in fact it holds heat. We both wake up with back pain. Now we’re stuck with it and stuck with poor quality sleep. If you’re looking for a new mattress, don’t buy this one.

Horrible

I waited to write my review. We've own our mattresses maybe a mo now and it's broken in to my liking perhaps not all the way though. Off hand it was a lil firmer than i would like. I got the plush and the other is the firm both in twin xl's. Ours is paired with an adjustable base in zero clearance status and king size bed. I have moments where i can't wait to get in bed. I thought with my ailments it would help a lil more but mine are mechanical. No matter what i choose the ailments will still be there. When i can sleep it's comfortable. I first tried this in the mattress store along with the kendall model which is just flat and more contouring because of the memory foam. However that model made it harder for me to get up although i loved everything else about it. I got a great deal with the sale price of $799 for each one plus $300 back in gc form which i received appox a wk or so after delivery. I knew what i was getting and didn't go in blind when purchasing. Although i use it with my base there are no dips or anything forming in the mattress. I wish it longevity of 12  yrs as my king koil mattress. It's worth the spend.
