Mainstays 2" Memory Foam Mattress Topper, Queen

This topper went on a budget mattress that wasn't as comfortable as we'd hoped it was going to be. And it made a very satisfactory difference. Super soft, so much so that at first we were afraid we'd made a new mistake, but after a few nights we give it 5+ stars. There is give on pressure points (particularly our shoulders) but enough general support that neither of us developed any back issues. We placed it directly on the mattress under the mattress cover. There was no slip even though it allows the sleepers to move around freely. Wonderfully, it's slightly bigger than our queen mattress so after placing the sheet the topper folds over the mattress almost like a hem, leaving no gaps or bothersome edges. Two inches seems cuddly enough without raising our total mattress height too much. You probably need to consider deep pocket sheets. It arrives looking like a big cinnamon roll, unpacks easily and was immediately ready for use. I have read that there is off-gassing with memory foam - it was not noticeable in this topper unless you buried your nose in it and after an hour it was all gone.

If this memory foam mattress topper gets 5 stars from me. Mattress topper had no smell, it expanded right out the box just give it a good 10minutes for full results. I got some new height to my original mattress, I love a bed with a little height, enough to climb right in. If you’re confused and going back and forth from Walmart to Amazon. GET THIS PRODUCT, ITS WORTH EVERY PENNY COMING FROM A PERSON WHO STAYS IN BUDGET!!!!!

I was scared when it first arrived because I ordered a king and when I put it on the bed, it was only half the size of it but after an hour, it grew to its correct size and it’s so soft! I literally sink in 3in…I’ve had other toppers but for this to be Walmart Brand…it’s good!

In use for about 3 weeks too soon to tell if this will provide the comfortable support needed 3 or 4 years from now. So far it's great. Shipping was quick and the price was reasonable. Took only 1 hour to return to full shape after unpacking. Just hand stretch it a little and it's fine. No holes or bubbles. Nice uniform light blue color. Perfect!

I LOVE this! I've slept on this for two nights, and no more back or hip pain. The negative reviews mostly state that it was squished and didn't fit the bed, and mine was like that too until I began shaking it out. I laid it on the bed, grabbed the side, and started shaking it, like I would do if I was making waves with the sheet (for the kids, cats, etc.), and it only took a couple of minutes for it to completely fluff out. I don't know if it would've fully fluffed on it's own--it's not like those mattresses in a box, it's a compacted piece of foam that may have been stored that way for months. I bought the 3" and it is VERY thick and plush. I would definitely buy this again.

This 3” Mainstays memory foam topper made a big difference for my bed. It’s super comfy and adds just the right amount of softness without feeling too squishy. It was easy to set up and expanded quickly. I sleep more comfortably now and wake up with less soreness. For the price, it’s definitely worth it and feels like a great upgrade to an older mattress.

If you have a mattress that is too firm, then buy this. I bought a mattress online and didn’t realize it would feel like I was sleeping on a sheet of steel. I couldn’t sleep well. I went and bought this memory foam, and it’s so comfortable. It’s the perfect amount of soft. It’s like I have a new mattress and I haven’t slept this well in years!

I will say that I love that this is made in USA, but if you need something supportive to keep your spine aligned while you sleep, IMO this isn't the topper for you (or for me). It did expand fairly quickly in a couple of hours and I did not sense a strong chemical odor like some manufacturers have (I'm very sensitive to odors). We bought a sleep number bed many many years ago and we bought the base model that doesn't have a pillow top built in. I regret that choice and we should have picked a higher model, but this bed has been good to us. I've noticed over the years, I just don't sleep as good like I used to. A sleep number bed is great as you can pick how firm or how soft you want your side. I thought I had my number figured out, but I guess I haven't. Thought this would be a good solution. I think it can, but I need a firmer foam topper to support my hips. I weigh around 120lbs and my hips bottomed out on this 3 inch foam topper. I put this down, then a mattress cover and then my fitted sheet. I took a cat nap and woke up pretty good. Spent the next two nights and figured out this isn't the topper for me. Because this is so vacuum sealed to fit in the small box, I knew I needed another set of hands to help me roll this back up. It was rolled from foot to head, then rolled from side to side. My husband is strong, but it took all of his might to help me roll this thing up like it came out so we could put it back in the same box to return it. His forehead sweated a bit and he was tired afterwards. It takes a lot to tire out this man. Boy am I thankful for his help.

I don’t know if it’s the quality or if it’s just because it’s synthetic but it’s so dense that air cannot circulate. Unfortunately, I was not able to use it because it traps the heat in. It made go to bed so hot. It was difficult to sleep. Otherwise, the condition was good. They synthetic. Foam smell could use about a day to air out.

After waiting for 3 days for it to relax and open up, I’m taking it back. Terrible experience as it is so heavy and smelly. Smells like hot plastic so I’m guessing it was stored improperly before Walmart sold it.
