I was very impressed with the quality, it expanded quicker than they estimated, but I did leave it out for 3 days just in case - and to help with any odor, as I’m hypersensitive to a lot of different fragrances/odors/etc. I haven’t noticed any odor at all! I actually had another 4” mattress pad on my bed and removed it to try this one - so I’m pretty familiar with them, but this one seemed to be better quality. It also came with a really nice cover that had a lot of cushion in it, but it was a little bit too small, and was really tight and difficult to get all the way around the pad and mattress. I’ve used it for 4 nights so far, and I sleep great, but my low back has been killing me ever since the 1st night. I was giving it a few extra nights, in case my body was just acclimating to it, but my low back still hurts. My old one had grooves in it, and this one is completely flat - so I’m not sure if that has something to do with it? Other than that, I love it!

This mattress topper way too soft and retains heat. It does not support your back. I do not recommend it.

Game changer on softness and comfort!

It is soft, yet supportive. I've only slept on it for a week, and I like it so far! Waking up with no hip pain.

This was by far the best topper ever purchased. Firm and supportive. Very pleased with product and value.

This memory foam topper is really soft. I got this for my daughter's bed. She loves it. It is too soft for me, but nice.

Super easy to install it just rolled out and expanded right onto the bed really upgraded our uncomfortable mattress and made it feel like new again. It is a very soft pillow top so if you’re not into a soft mattress may not be for you for us.

Disappointed. Topper is hard as a rock and has no cooling properties at all. Bad enough that I am writing this at 2:30am wishing I had not taken my other topper off. Topper is so hard it is hurting my shoulder. What a waste of time and hopefulness.

I give the product a 2 as it is comfortable (just not cooling) and Sams a 1. Topper sleeps noticeably hotter than without on a foam mattress so I’m guessing someone provided a hefty incentive for all those 5 star reviews. This is an unbiased un-incentivized review.

This is an absolute game changer! I’m so so in love with this mattress topper and I haven’t slept this well in years. It definitely needs to be aired out a bit when you first receive it but I’m definitely considering buying one for every bed in the house!
