SINWEEK 3 Inch Gel Memory Foam Mattress Topper with Cooling Cover Ventilated Soft Mattress Pad, Bed Topper, CertiPUR-US Certified, King Size

Used this on an old spring mattress that is very hard. I didn't have high expectations for it, bc.. I mean... its foam. I couldn't believe how much of a difference it made. It was just the right amount of soft and firm and cushion. When you get a foam topper you think, "Is this thing just going to collapse and make me all uneven?" But it actually worked very well. I told my spouse that I might get more. When it arrived, I allowed it to fully open up for a few hours before I inspected it. When I first took it out, it looked like there might be some damage on one of the edges, but no. It just needed the fully few hours to open up. I would highly recommend it.

My Bestie is disabled and needs bed support. This came in a small package and was easy to pack for our hotel bed on vacation. It rolled back up tightly like a sleeping bag. This would even be great for camping. Super comfy, great support, good quality. Good price. Ordering another to pack for our upcoming cruise.

I’ve bought three of these so far—one for each of my daughters and my son. They add a bit of extra cushion without being too soft or squishy, which is nice.Each one took a different amount of time to fully expand. The slowest one took about 3 hours, so if yours doesn’t puff up right away, just give it a little time.

Used over an older mattress in guest room. Regular visitors said it was a great improvement. Fit and quality are very good. Can’t give 5 stars until I use it myself.

I tried an experiment when I received the package and removed it from the box. I actually allowed the mattress foam to expand not just within the bare minimum timeframe which they suggested of 48hrs but I actually waited past the 72 hour mark before sitting or laying on the memory foam. I think it may have made a difference actually allowing it to expand to its full capacity. Just a tip for someone who is considering purchasing this product. It took some discipline but I was able to put off the instant gratification to reap the future full comfortability of the foam mattress. So far so good!

I had to temporarily set up a pallet on the floor while my mother visited and used my bed. The chair I have that folds out into a "bed" is fine napping on, but to sleep on it all night caused me back pain, so after researching and reading lots of reviews, I settled on this mattress topper and I'm glad I did! It has has made a world of difference! My only regret is that I bought the 2 inch topper and I wish I wouldl have bought the 4 inch.

Bought the 2 inch twin size for my daughter’s spring mattress because she was complaining she could feel all the springs when she lays down. I slept on her bed and at 210lbs let me tell you, that mattress itself was trash. Ordered this topper, unboxed and fluffed the compressed areas just like the video suggests. Took all of 3 minutes to get it fully decompressed. The topper has a slight odor but that’s expected so no big deal. Letting the topper air out for a few hours got rid of the smell as far as I can tell. Tested the mattress with the topper and couldn’t feel any springs while laying on it. We’ll see how it holds up over time but as of now, I’m 100% satisfied.

Soft. Almost like yellow polyure foam from the 80s. It slides aound. I secured mine to the corners with two sided carpet tape. Its not a terrible item and considering cost desreves praise. Maybe it feels different on a larger bed but on a twin, I would compare it to a typical yellow foam mattress topper like you used to get at department stores.
