We tried the ProAdapt firm and also loved it but were scared off by the price tag. We ended up with the TempurPedic Supreme Firm from Costco and love it. We think it feels similar and it was almost half the price, plus the Costco backing and right now they have a $300 gift card promotion too.

That's what we bought! I have a bad back and was very concerned that this would suck after six months. There's a bit of a hump in the middle where we don't sleep, but it's held up nicely for nearly two years now. I love it.

Im digging the Costco Tempurpedic, the non-hybrid medium one! Its my first nice mattress, and I feel like I can not worry about whether it will sag or not because of Costco's killer warranty. Roughly 6 months in, break in was maybe a month, and it wasn't bad during that time. Very happy.

It's a Tempurpedic, Costco gets store-specific models. Their Tempurpedic Supreme falls between Pro-Adapt and Adapt - it's using the foam from a version back (good thing!). More detail here: [https://www.reddit.com/r/Mattress/comments/1h5s1o2/any\_longterm\_costco\_tempurpedic\_supreme\_owners/](https://www.reddit.com/r/Mattress/comments/1h5s1o2/any_longterm_costco_tempurpedic_supreme_owners/) It's not about price, it's the massive number of horror stories on reddit that did it for me. People invest 5k in a high end Tempurpedic, it sags in a couple of years, and the warranty is designed not to applicable. Gross stuff. However, Costco is no-questions-asked. For me, that means I can take the risk, not feel like I'm gambling, and if that horror story happens? Back it goes.

The Firm Adapt and Proadapt were crazy hard, they didn't feel comfortable to me. Soft seems great in the higher models, but I worried about longevity. Costco has medium, so I got medium.

6", 160! Firm was too firm for me, in-store. Medium is a great balance, Soft was a marshmallow in a good way, but I worried if it'd soften MORE over time.

My first two mattresses with Costco (traditional spring based) were duds. The first one started sagging within a couple years, the next one within a couple months. (Yes, they are on a box spring). Earlier this year, I splurged for a temperpedic with Costco, about $1800. It's been a dream, literally. The return policy makes it all worth it. Even the mattress that was like 2.5 years old, they picked it up and gave me my money back, no questions asked. Truly a risk-free guarantee. Edit to add: I also have a Costco mattress in my guest room, but that's rarely used so can't comment on durability.

Do not get a tempur pedic. I made the mistake of buying one from Costco and loved it at first. It was a great bed for 10 months. Despite rotating it and do everything else it started sinking deeper and deeper. By 1 year I started getting severe back pain due to it. I then got the sleep science on a whim. One year out and no sign of sinkage… yet.
