r/Costco on Reddit: Anyone with experience with buying a mattress from Costco
October 24, 2024 -
So my husband and I need to get a new mattress and are thinking about Costco for it. We bought a brand new mattress at a random mattress store back in 2017 right after we got married. In less then 7 months it had formed huge divots from my husbands pressure points down the bed. You couldn’t find anywhere to lie comfortably. We tried taking it back to the random mattress retailer after 7 months and they said “nope, so sad. Would you like to buy a NEW one?” So our supposedly first big purchase after getting married turned into a huge waste of $2k bucks.
Since then we have literally bought second hand mattresses when needed at a fraction of the cost. Things were great with that until my dear mother came to visit. You’d think she slept in an Iron Maiden. She then tears the sheets off and saw it had a goodwill tag (the horror). I can’t describe the mix of anger, bewilderment, disgust, et al that came from that woman’s mouth. (I hurried and grabbed the sheets before she saw they were from IKEA just in case that was an issue!)
That brings me to my question for everyone. Anyone acquire a mattress from our store and savior, Costco? I’d like to get some different opinions but let’s be real. The ONLY thing I care about is the return policy. The 2017 divot debacle cannot happen again! Id like to know that if anything happens all I have to do is take it back like that 2009 sofa set, those too small pants and anything from Amylu (sorry guys. Just ew) Thanks for listening! And sorry for any grammatical boo-boos, I’m on mobile
Edit: I really want to thank everyone who commented on their experiences. I have a great idea on what we are going to pick. I’ll update the he post in the future once we decide!!

We got our novaform king mattress there a few years ago. Still love it and way cheaper than anything else we were looking at.

Our solution (which took us over a year and a variety of mattresses to discern) is a bit unconventional, but highly recommended. We are large, tall side sleepers, both of us. But we are nearly 100 pounds different in weight. So, our support needs are different even though we want to sleep side by side. We need a king size mattress/ sleep surface. Here's the brainwave: two XL Twin mattresses strapped together make a bed the size of a King. We ordered one for each of us from Costco in the firmness we like with the coordinating foundations for each and a memory foam topper also in our preferred firmness. We used Velcro straps to lash the foundations together and we can sleep next to each other now without disturbing each other with movement or one of us being uncomfortable to accommodate for the other's sleep preferences. I buy XL Twin mattress covers, King Size fitted sheets, and XL Twin flat sheets. We both use our own blankets and I'll toss over a king size duvet if I want it to look pretty. I hope this helps! It saves us a ton of money and just as much sleep. Best of luck!

I’m looking to buy King size mattress at Costco after years and man they’re so many different brands now! Details are in the title. Cooling feature might be good to have! It would be for me & my senior pup (I will add waterproof cover). I don’t have a specific budget because I see so many of them at different price point.
Thank you!

Don't buy a foam bed in a box. They crater way fast. Also, stay away from pillow tops for the same reason.

I’ve got the 14” Novaform comfort grand and the 3” serenity tempur-pedic topper. I’m also a side sleeper w back issues and put a waterproof cover on, 3 dogs…. It’s been nice and I’d do it again. No dips or dents after a few years now.
