Serta Perfect Sleeper X Knox Hybrid Mattress

Already showing body imprints. Not really "cool" sleeping. It's just ok.

Disappointing

Serta

Great mattress

I wanted a firm mattress and I found the perfect one.

Super firm

No more aches and pains when I wake up in the morning.

Very Comfortable

This mattress is very firm & comfortable mattress.

Serta Knox Firm Mattress

Serra Mattress

This mattress is so comfortable. It gives to your body but also supportive.

Extremely comfortable

I've only slept on my new mattress five nights and I really like it already.

So far so good!

Supportive yet still feel I can sleep on my side comfortably!

Excellent

Four months in and this is not good. Much like another reviewer, there’s now a sink hole and I can’t wait to get out of bed because I have to, to stop the aches. Four months, $1000.00 in and I’m stuck with waking up to aches from a mattress. This is really bad, Serta.

Sink hole four months in

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.
