You might want to try the: Sealy Posturepedic Plus Prosser Hills 13.5" Plush Mattress. We just returned ours back to Costco Friday. It was supportive but too soft for us. You may like it.

We got the Sealy Posturepedic Plus Prosser Hill 13.5" plush king mattress about 4 months ago and so far we're loving it. We both have back problems and neither of us are having any issues so far. I'm a back sleeper and my wife is a side sleeper.

Five months ago we got the Sealy Posturepedic Plus Prosser Hills 13.5" Plush Mattress king, with box springs. So far we love it. We did a LOT of research and narrowed it down to looking at CostCo mattresses that were not rolled up/flattened/boxed/shrink-wrapped for delivery. We also wanted inside delivery, setup, and haul off of the old mattress. Over the years we've tried various options - our favorite was a 100% foam latex mattress that was flippable and not compressed, I don't recall the brand. It lasted for 7-ish years before the grooves/sags got to be untenable. Given how expensive it was we weren't ready to do that again so we looked at other options. We tried several mattresses in a box that came flattened then expanded after unpacking. Most were great for a year or two but then started to sag way too much. When we moved into our current house 8 years ago we got a traditional coil mattress and box spring which was 'okay' but lasted 7 years (don't remember the brand). So, our direct experience said either 100% latex foam (too expensive) or traditional, non-compressed mattress. We also wanted the simplest possible return process if we didn't like it, hence CostCo. That being said, mattress preferences are highly personal so your mileage may vary from anyone's advice, including mine. That's why we chose CostCo, for the ease of changing our minds (which we haven't had to do yet).

Yeah man, I hear that. I’ve been having problems from an overloaded delivery route for the last 10 years. I returned a firm Sealy posturpedic plus a while back, the previous model to these newer ones. And I’ve tried and returned countless mattresses over these years with no success. I’m in the process of trying to get layers for an all foam DIY.

Better research more and try more. I had some of my best sleep in my sister’s single bed in Australia, it was Sealy. Years later after getting married, I decided to splurge on a good King size mattress and bought a Sealy Plush medium firmness for around rm10-12k after discount. Damn, after a couple of years, the bed lost its firmness and we had back, shoulder aches. Their advertised titanium coils are BS. Put up with the bed for 7 years because it felt such a waste after spending that much. Now I’m looking to replace my bed and I’m staying clear from pocket spring beds, they just don’t last long and offer a good back support. Most of the famous premium brands unfortunately use pocket springs, e.g Serta, Sealy, etc. I’m now looking for a bed with a combination of coconut husk fibre & latex, very few have that. Getha has a few models but also extra other foam layers at the bottom, e.g Icon & Genetics model. Another option is Fibrelux with a latex topper.

The boring mattress founder trolls reddit to post and prop up his own product. But goddamn I just bought a queens hybrid because I was only allowed one 100 sleep night with T&N and I wanted to try out the Mint Hybrid because for some reason during Labor Day it was cheaper than the regular queen hybrid. Turned out way too soft. Boring mattress queen hybrid about half the cost of T&N and turns out to be pretty much exact firmness I was looking for. That also said, when I moved the T&N mint to the floor for the two weeks when both overlapped — the support on the ground made that mattress also pretty damn comfortable in a different way. Also slept on a pillow top sealy mattress at a Hyatt, was one of the absolute best nights in a bed I’d ever had. There is a purchase program. I did look into it. But I’m fine with the Boring one I’ve got now.

I have the same issues. I haven’t found anything that exceeds my mattress/box spring combo for comfort or longevity.

Big fig has a new luxe version that you might like. If we hadn’t already bought the sealy posturepedic. I would definitely have tried this one. This Sealy mattress has become annoying to me.

I'm a bui bui. My Sealy Posturepedic is still firm and holding up well after 6 years of use.
