Mainstays 8 in Memory Foam Mattress, Twin

This mattress exceeded my expectations for the price. It arrived well packaged and expanded quickly after opening. The 8-inch thickness provides good support while still being comfortable, especially for sleeping on my back and side. The medium-firm feel is balanced, not too hard and not too soft. It offers great value for money and feels durable and well-made. I've been sleeping much better since using it and would definitely recommend it to anyone looking for an affordable and comfortable mattress.

So I waited a copy of days to post my opinion! Me and hubby were having trouble getting rest ..so I decided to buy this item …let me tell you it is very comfortable. It expanded amazingly well maybe even bigger.. I follow all instructions—- no smell ..All comfortable I got a queen size price was good. Thank you

Let me tell you the mattress is quality as far as comfort Bt definitely not the inch it's suppose to be which is fine you get what you pay for so no complaints in that area. Bt what I will complain about is the delivery %26 Walmart customer service is negative zero. So rude inconsiderate %26 unprofessional. How do you advertise certain shipping for plus customers bt not fulfill? Horrible! Just take that into consideration when ordering may take a week to deliver

Great mattress for the price. It shipped quickly. Once out of the box it fluffed up quickly. The bed is comfy, however it's not that "firm" which with memory foam I should have known it wouldn't be as firm as I needed. But if you like a softer mattress this is perfect.

It's a great starter matches for being a firm and memory foam and 8 inches thick so if you got a kid that's you know 6080 even maybe 100 pounds. It'll be fine but if it's something you're looking to buy to use long-term or you know a few years to come not recommended as my son‘s only been using it for a couple weeks now and his body impression. My UN is 58 pounds is already sunk into the middle of the mattress. It already has his body shape so as he grows, it's gonna be more and more uncomfortable not to mention it comes up tight air roll in a box like vacuum sealed bag and when it pops up each end of it is still squashed and it has been like I said two weeks now so it's kind of awkward shaped Other than that it's a good deal

Initially really pleased with this purchase and still think it is very good value for the money. it is well made and comfortable BUT it would hold up better under lighter bodies, or for short term/occasional use. After daily use it has developed a compressed area. I am going to flip the mattress and see if that helps to extend its life, but i don't expect that the foam is really going to hold up for a full year.

There is not one thing about this mattress that is medium firm! Please do not be misled by others, this mattress is entirely too soft to be supportive in any way. You will sink completely down to the bottom of this mattress and feel every rail, or slat, or bar of whatever type of bed you have. Please do not waste your money, or the headaches will begin! I didn't even get to sleep in it. I sat and immediately sank to the bottom. I lay down to see if maybe weight distribution would help. It didn't. It made it worse because a canyon developed that I couldn't even roll my body out of to get up, I needed help! I was duped by the price, and by Wal-Mart thinking this was the deal of a lifetime...a queen mattress for $124! That adage of if it sounds too good to be true, it probably is, and definitely was with this purchase! Now I'm stuck with a mattress I can't use. Please don't listen to the fake reviews that say this mattress is a glorious find and an unbeatable price! It's a lie. It is awful. It is horrible awful, and Wal-Mart....you should know better! I DO NOT RECOMMEND THIS MATTRESS!

This mattress never expanded to its full size. I reached out to customer service through the chat option and was told I would receive an email to submit pictures in 48 hours. A week went by and I never received an email. They also asked me if I wanted a refund or wanted to return the mattress. I called customer service and they said they couldn't pull the chat and that they could give me a $25 refund. I purchased one of these a year ago and it was firm, and expanded to 10 inches. This is not even the same mattress!! Really disappointed with the customer service and I wouldn't recommend this brand again.

I bought this mattress just three month ago, and it's already sagging badly in the middle. It's very uncomfortable and provides no proper back support, which has worsened my spine/back pain. The quality feels poor and not worth the money. I would not recommend this mattress, especially for anyone with back problems.

Very soft, no support for back or body. It hurt my back, so I returned it at the pick up line thru the Walmart app. I will only sleep on a firm for now on. This one is medium firm but it's extremely soft. I'm a female, short and about 130 lbs. Zero support!
