I currently have the Sealy Mount Auburn purchased in 2021. I previously had a cheap Zinus MF, and it was definitely better in comparison. However, I found it to be quite firm and started the long journey of matress toppers to gain better pressure point relief for side sleeping. The matress is in perfect condition with no sagging, but after 4 years, I feel it's just not for me. It's not bad but not great. I highly recommend a sturdy wooden frame/foundation as it did improve my comfort level some. Buying from Costco is always a win with the service and return policies, so trying it is literally risk-free.

I’m definitely no expert but what angered me about my last mattress was not only that it lost all its support within a few years, but it had like zero edge support so a couple of moments being seated on the bed and I’d slide right off. So when I bought this one, I chose Costco because they’d dispose of that old mattress and deliver the new one quickly - and if I hated it too, they’d take it back. My bed is full sized so I didn’t have unlimited options so I went with Sealy Posturepedic Plus Mount Auburn 13” Medium - it had mixed reviews here, but seemed super sturdy and had special construction ensuring edge support. I also got the Serenity by Tempur-Pedic 2+1 Pillowtop Mattress Topper. Together, they’ve been with me nearly a year and just as supportive as the first night.

It’s been a year since I bought my mattress, and I still love it. I got the Sealy Posturepedic Plus Mount Auburn 13" in Medium firm and topped it with their Serenity by Tempur-Pedic 2+1 Pillowtop Mattress Topper. I’ve found in recent years that pillow top mattresses don’t seem to wear as well, but toppers are relatively inexpensive and I can replace to suit my comfort. The white glove delivery and removal were seamless and overall it was just a really great experience.

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.

I had a posturepedic sealy from Costco that lasted a good 6 years before going to shit. Always had a topper though.  I wouldn’t buy a mattress from Costco again no matter what the brand is

I went with the best Costco had at the time which was a Sealy and then added a 3 inch memory foam topper. I sleep in all positions...side, stomach, back and it's very comfortable. Now I need really deep pocket sheets, but that's manageable.

We have a sealy posturepedic from Costco and it says medium firm but imo it’s definitely firm enough for cosleeping - a thousand times better than the foam mattress we had before

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.
