Soft, cushy melt

After almost 20 years of trying to sleep with a human burrito, we finally decided to sleep in separate beds! It didn’t really matter to him because he actually does sleep like a rock. But I couldn’t take it anymore! After hurricane Ian used my previous mattress (mem foam) as a giant sponge we set out to find me my perfect mattress. I am disabled. I am fortunate to be able to afford this price range. After one daylong search, I got it down to 1 of the iseries from serta; and people, the second that I laid down on the hybrid plush 4000 I was in heaven: ) I am still in heaven! It’s so well crafted and yes, you Can feel the cooling sensation!! I do have it on top of a Rize adjustable frame that I also adore. At 1st I was worried that, with the thickness of the mattress, I wouldn’t get the same quality “feeling,” especially in zero gravity ( my favorite position) but it’s just fine; I can even feel the different massage levels through it!! I’ve been sleeping like a teenager ever since my 1st night - for me and my body, that is a miracle. So, obviously I Love my new mattress!! The store gave me a written guarantee of 120 days sleep trial too!? I must add that by the time we got to this store we were both very hungry and tired and the salesman was a bit pushy and we were really getting ready to actually walk out and get something to eat, but the salesman finally blurt out a price that was discounted by almost $700 so we had to jump on that deal, hungry or not. You can haggle, just be polite and firm. I was very surprised and much happier as we were planning on returning the next day to buy it anyway Lolol! It’s a big investment for most people, but the right mattress will last for a long time so go for it if you can. Sweet dreams to everyone zzzxo
