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.

Ngl I have a posturepedic that’s like 20 years old too (it’s been used on and off, not continuous) and I’m dreading the day I have to find a new one. From what I’ve seen most mattresses aren’t flippable anymore and seem to wear unevenly.

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.

Hello, wise mattress guru! I would love your thoughts, if you'd be so kind. Sorry, in advance, for the length of this. Okay, here goes... In my entire life, I have only slept on innerspring mattresses with box spring foundations. The last mattress I purchased was in 2004, and desperately needs replacing. Actually, as a whole, the mattress, a Sealy Posturepedic I believe, has held up unfathomably well, and most of the mattress is still in excellent, very comfortable condition. However, on the side I sleep on most, and particularly the one area I sit on regularly there, it has for the last 4 years had an approximately 18" x 18" (butt sized) divot with a couple of springs popping through. Because it's a queen bed, I sleep as far away from that divot as possible, but can still roll into that deep divot if I get too close. Also, just from a housekeeping standpoint, I wouldn't mind having a fresh mattress. It's not that I'm not willing to buy a new mattress, but everything about mattresses has completely changed in the last 20 years. In the last 4 years, I've done tons of research and read hundreds of reviews, and still haven't gone through with a purchase. I do not want a bed that sleeps hot. I'd also like a mattress with longevity. In the past 6 months, I have recently read a lot about latex mattresses and how they sleep cool. Now though, I'm reading that they are only cool in comparison to memory foam mattresses, but that they still hold the heat. I've also seen many suggestions to "build your own mattress" and while that sounds appealing, as a single senior female, I'm not able to haul anything heavy up to my second floor bedroom or to dispose of my old mattress myself. That has me thinking that I'm better off with a seller who offers both white glove delivery and removal of my old mattress. Long before I needed a new mattress, I was intrigued by the individually pocketed coils of a Simmons' Beauty Rest, and there is one other brand that I always used to promise myself I'd own one day. That brand is the magic word you mentioned, Shiffman! I'm not sure that they're still made the same way as years ago, but back in late 1980's my parents bought a Shiffman through Bloomingdale's, and that is hands down the best, most comfortable mattress I've ever laid on. Also, the quality was superb, and it remained in the same great condition for over 25 years. Yes, it was expensive, and yes, it required flipping, but feel-wise that mattress remains my definition of a dream mattress. My questions are: Can you please comment on all Latex mattresses and Latex as the support layer? Is it much hotter than going with a traditional innerspring mattress? Also, I was once told by a salesman at Bloomingdale's that the Shiffman requires a traditional box spring foundation, and cannot be used on a platform bed. Is that true? I've always had a box spring foundation, but wouldn't mind losing the fabric covered box spring since I have allergies, and I also find the look of a platform type foundation cleaner and more modern. While I don't have $10,000.00, $20,000.00, or $40,000.00 to spend on a flagship Shiffman, Iast time I checked, the prices of Shiffman through Bloomingdale's and other retailers were not that out of reach. I no longer live in a state that has a Bloomingdale's, but there is a small, old school furniture store near me that exclusively sells Shiffman and no other mattress brand, and they told me they have models starting around $2,500.00. I read, but didn't quite understand, your thoughts on Shiffman as sold through big retail chains vs independent furniture stores. Could you please explain. If necessary I could order through Bloomingdale's in a neighboring state, but that means I wouldn't be able to to test out the mattress in-store first. Also, I'm only 5'2" tall. The big problem I had when last purchasing a mattress was that mattresses had become super thick. Most mattresses combined with a box spring were suddenly far too tall to allow me to easily climb into and out of bed. I ended up having to go with a low profile box spring, but I'm not sure they're even offered anymore. I'm okay with the new bed being maybe 2" taller than what I currently have, but don't want something so tall that I need to take a running leap to get into it, or have a big drop to the floor to get out of it. Also, I'd like a mattress with excellent edge support, since the edge that I sit on is always the first point of failure. Any thoughts or suggestions you can offer would be greatly appreciated. I don't know if I should go with a new type of mattress like a Latex mattress, or a Build-Your-Own mattress, or if I'm simply better off sticking with a traditional Innerspring Mattress that I'm used to. As for the innerspring mattresses, what are your thoughts on Sealy vs Beauty Rest vs Shiffman? I don't want to spend $5,000.00 on a Beauty Rest Black, but I'm wondering what their other models may be like. Since you are literally the only person in any thread I've read that even mentioned a Shiffman, I'd love to hear your thoughts. Thank you so very much, in advance!
