Excellent support with softness! Longevity is questionable.

I bought this one at Costco, but it's the same as the other branded versions of Sealy Posturepedic Response Premium Plush Pillowtop 14". (A good source is US Mattress dot com for the various names this goes under at any given time across retailers.) So, the price is excellent, and I got it on sale to boot. And out of all the mattresses I tried, I realized I hated the sunk feeling of memory foam, preferred good edge support and the springy feel of an innerspring, but absolutely require both amazing alignment and back support while sleeping on my side as well as zero pressure points. For reference, I have a very curvy body build with wide hips, small waist, large chest and medium shoulders. I am almost always a side sleeper, but do wake up on my back sometimes. This mattress is great for me for BOTH positions - I am always cushioned and held in alignment. AMAZING!! I do wake up in some pain at times, but I have some other issues going on that are causing that. The mattress itself has been really good for alignment. That "posturepedic" support thing is real! But, I fear for its longevity. The soft foams I need for cushion and pressure point relief do start to develop body impressions pretty quickly, and you have to rotate as well as sleep all over the mattress to try to keep permanent body impressions to a minimum. The great thing about shopping mattresses at Costco is they will take it back and refund you fully anytime during the warranty period (10 years for this one) if the mattress fails to meet expectations. So, I'm going to go with it for a while, and see where it gets me. Once the stores are open again post-Coronapocalypse, I'll also be checking out the Purple 4 (but really: it's too heavy to be practical, and you're not supposed to use a heating blanket which I always do in the winter) and the new Casper Nova Hybrid. The Nova Hybrid actually sounds pretty perfect for me except that edge support seems not that great - not a HUGE deal, but I like having it. Hope this review helps you!
