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!!

I put off getting a new mattress for fourteen years because they’re so expensive in stores. I finally bought one on Amazon after my mom had ordered on Walmart’s website.

I was very apprehensive because we couldn’t try it but I read hundreds of reviews.

It was super cheap. Less than $200 for a queen. This was five years ago.

It’s the best mattress I’ve ever had.

Getting it in the mail is much better than getting it delivered by the store.

ETA: It was ZINUS 10 Inch Support Plus Pocket Spring Hybrid Mattress

r/Mattress on Reddit: Recommendation for Box Spring to go with King Costco Stearns & Foster 14.5" Lakeridge Mattress
March 29, 2022 -

As title says, just bought the king size mattress from costco and they were sold out of king size box spring that normally are paired with S&F mattress. So, now I am chasing a box spring. Would like something that is quality and don't mind spending more if necessary.

Costco has a EnForce 7" Metal Box Spring (Link to Costco provided)

Amazon pushes the Zinus 9" Metal Box Spring (Link to Amazon Zinus provided)

I should add that she does want a higher profile w/ legs.

Should I go w/ metal or a traditional wood box spring? My wife wasn't thrilled with the gapping on the Zinus box spring (worried that it isn't providing enough support) but that could be our ignorance of what is really necessary.

Would somebody point us in the right direction as I am confused and need to order in the next 48 hours.....?

Thanks in advance

I’m thinking of purchasing a new king mattress set from Costco, but none of the descriptions tell me if the box springs are one solid foundation or if they are the traditional two. If you have purchased a king mattress from Costco with the matching box spring could you let me know what kind it was? Thank you!
