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!!

r/Mattress on Reddit: Costco mattresses are great for frustrated shoppers
January 27, 2024 -

This sub is full of people rightfully complaining about how the sub makes mattress shopping even more complicated and doesn't offer a Best Mattresses list. So here's my attempt to help:

I see no reason to shop anywhere but Costco for the following reasons:

  1. Return Policy - I think everyone is aware of this. You can return a mattress at any time whatsoever as long as it doesn't have bodily fluid stains on it (as that's a biohazard). Easy way to ensure this is to immediately place a mattress cover on it

  2. Delivery Policy - I order online and an upper end mattress comes with white glove delivery, and if I return it, they come pick it up

  3. Limited selection. This is the point. Too many choices psychologically overwhelms us as humans. A more limited selection across several brands isn't going to frustrate us as much - and guess what? Their selection is wide enough that it can still frustate someone if that's what you want 🤣

  4. Price. Can't beat it across several brands.

I got several Sealy posturepedic plus until I settled on the Mt Auburn medium for less than $750 for a queen.. My experience is that it is indeed hard as rock when first delivered, but softens up significantly after a week or two. Now it's medium firmness to the point where I'm even wondering if I want something firmer, in which case I may go for the Sterns and Foster.

I actually love a plush mattress but plush as in a nice plush top over a firm or responsive surface; whereas I don't like sinking into a mattress much. One reason my favorite in hotels can be the Simmons Hyde Park Plush, which they no longer sell, but I don't sink into the mattress.

Best of luck to you all. If you want to save yourself headache, just get a Costco membership, go to your warehouse if you want to see what they have, and order it online among the options

Mattresses to check out, as well as customer feedback as to actual firmness:

  • Tempur Cloud-supreme (medium plush) or Supreme (firm) - discontinued models still offered at Costco at a discount

  • Tempur Prima Flex Hybrid (medium-firm bed in a box)

  • Sealy Posturepedic Plus 14" Hybrid Ridgecrest II in Plush (too soft for me, was like sleeping in pudding) and Firm

  • Sealy Posturepedic Plus Hybrid Mt Auburn 13" (Medium)

  • Kirkland Sterns and Foster Hybrid Lakeridge 14.5" (Medium-Firm to Firm, plush top with firm surface beneath

  • Beautyrest Silver Hybrid DualCool 14.5" (Plush to Medium)

This is a great list from which you can narrow your search.

Also, I will say this much. I'd actually love to make my own mattress as a hobby. Have read so much about it that the idea of buying a pocket coil system and topping it with different layers of foam or latex seems appealing to me for fun even while I have a great mattress already. Just experimenting to make something great. But I ain't gonna let finding the mattress I sleep on take my life away and add stress haha.
