I am very pleased with this mattress topper so far. There’s a noticeable difference in softness and the mattress feels much more comfortable with it on. It feels like a nice hotel mattress now! It’s exactly the feel that I was going for! It was easy to put on and my sheets still fit easily over the whole set up. There was no smell to it whatsoever.

I purchased this to replace a foam mattress topper and I'm so glad I did. It's extremely comfortable and offers lots of padding so long as you follow the instructions. I opened the package and let it puff up on its own for about 30 minutes before tossing it in the dryer on air fluff setting. It's been about 2 weeks and I have zero complaints. It's really comfortable and has worked wonders for my chronic back pain. Would definitely recommend.

Super soft and comfortable. I just wished the corners were deeper so it would stay on the mattress better.

This mattress topper is so comfortable thick and flush. It turns your firm hard mattress into something soft and just dream like I purchased one for all of the beds in our house. I would definitely recommend this. I’m not sure about washing the king size one in the washing machine, though it’s very thick there was no smell or anything to them. I like this product.

This pillow top cover is a great, budget-friendly option for revitalizing an older or overly firm mattress. It delivers excellent, cloud-like softness right out of the box and features deep pockets that ensure it stays securely in place. While it may not provide the firm support some need for back or stomach sleeping, it is a fantastic upgrade for side sleepers looking for more cushioning.

Bought this to add a little extra softness to our mattress. Nice quality but after the first couple nights of sleeping on this it seems to have flattened out, lost the fluffiness. True to size not sure that it has “a cooling effect”. no smell to the topper. If your looking for a way to make your mattress softer I would just recommend buying a new mattress and not waste your money on mattress toppers

Surprisingly comfortable. Bought a firm mattress to help my back but the mattress was too hard. This topper worked perfectly. Maybe too fluffy but for sure fixed the brick lard mattress.
