the morning Slumber medium mattress appears to be of good quality, although it's listed as a medium and I believe it leans it self towards the firmer Edge of medium. I am very pleased with this purchase. I tried a different model mattress several months ago and after sleeping in that one for about a week and a half it was already sinking in the middle and of course I returned that one. yes I would buy this morning slumber mattress again. I hope this review helps you in your quest for a great night's sleep without breaking the bank. kind regards!

I am so glad i purchased this mattress set! it is so comfortable! I've slept better the last few nights than I have in years. I stay cooler with this mattress too, which is awesome! i also bought two queen size mattress sets. My kids are in love with their sets as well. we havent had thrm long enough to know about longevity but I'm praying they last a long time.

Oh Em Geeeeeeee. Wasn't even really thinking of buying a new bed. Then I just passed by it in store and it was too good a price to not get! I have been sleeping in it for a week now and it is hands down the best sleep I have had in so long! It's more firm and doesn't let my body sink, it cradles all the curves.

Great mattress for price

​I am beyond impressed with the Serta Classic Morning Slumber 11.5" Queen Mattress Set. Finding a complete set that includes both the mattress and box spring at such a great value is a huge win, but the actual sleep quality is what truly makes this a 5-star product.

went from a high profile bed to this. my back was hurting every morning. we got this matress i was not impressed at the low profile at all but i b sleep like a baby. it was a good choice for the price. i feel like it was made for me.

Upgraded to a Serta morning slumber and couldn't be happier. Delivery was smooth, the mattress expanded perfectly with no weird chemical smell, and it is incredibly comfortable. It's the perfect mix of soft padding on top and firm support underneath.

The queen size is much smaller than the queen size I had before. There are approximately 2- inch spaces on each side between my bed rails. My previous queen size fit more snugly between the rails with only about a 1/4-1/2 inch gap between the mattress sides and rails.

I purchased this mattress on May 22, 2026. I didn't realize Sam's uses a third‑party vendor for delivery, so when I started receiving text messages that looked like spam—just random numbers with no clear identification—I ignored them. Once I realized they were legitimate, I scheduled a delivery for June 23. On June 26, I contacted the third‑party delivery company for an update and was told my order had been canceled. They stated Sam's Club canceled it and directed me to call Sam's for more information. I called Sam's and was told they needed to research the issue and would call me back the next day. Four days passed with no response. When I called again, I was transferred to someone who identified himself as “Steve” from the escalation department in the Philippines. When I told him I planned to leave a negative review, he immediately gave me a different name and said he did not have to provide an ID number or any other identifying information. I explained to him that I had already contacted the third‑party vendor and they told me to call Sam's, and now he was telling me to contact the same department that had already directed me back to Sam's. I told him I was not going to “chase my tail” going back and forth between two departments giving me the same answer with no explanation. My order was canceled, my money refunded, and I still have no explanation as to why. I have company arriving for the Fourth of July and no mattress. Save yourself the time and frustration and purchase a mattress from another retailer.

I returned this mattress set after sleeping on it for 5 nights. I am 120 lbs. The bed was too firm. It had a top layer of about 2 inches of soft foam on top of something quite firm. It also felt like it was already sagging. But everyone is different. I'm just glad of Sam's Club return policy. But I will never buy a mattress from here again unless it's there's a great deal for kids' beds.
