The worst

Absolutely no support from this mattress topper Tried it half a nite and when i tried to get out of bed my back was in such pain i could not walk. Took it back and was happy to get my money back.

Nice

The foam is not too hard, but not too soft. The cooling is so-so; like many products, you can feel the coolness initially and then it absorbs your body heat, which negates the product's cooling capacity.

Decent topper for the money

Thx topper isn’t as firm as I would like, since I have some back problems, but it is better than the tempurpedic one I tried. It is comfortable for most people. The 10 year warranty will never be used since it states it has to be depressed 1.5” before it can be utilized. If I waited that long I would have many more back problems.

The worst…

I wish I could give zero star… it’s cooling for first 10seconds then it’s not at all… we have back injuries and every morning we woke up with terrible pain of body. It’s bad but it’s even worse with this mattress.. I wish income return it but we are stuck with it. I don’t know how some reviews said comfortable. Maybe they never bad back injury.

Made my mattress even better. Relieves pressure on the hips. This is my second purchase as I’m placing it in the guest room. I can’t say enough good things about this pad.

Don’t think twice about this! Just do it!

This bed topper is absolutely AMAZING! The foam is so soft, yet so firm! The cooling effect is my favorite part. There is a noticeable different. This took my bed from 10 to 100! If you’re looking for a sign to just buy it, this is your sign! Your back will thank you!

Give it Time

I purchased the 3" topper 6 weeks ago as a solution to my uncomfortable bed. I noticed an immediate improvement. Here is a list of my observations so far. * The mattress topper is soft but firm enough that I don't feel like I'm sunk into a hole. * I don't feel a 'cooling' effect But, It does not retain heat, which is perfect for me. I also have a mattress pad over the topper, which I will remove once the nights get warmer. I will update if I notice a difference. * It took my body a few weeks to adjust. At first, I woke up with neck pain. I realized that my neck was positioned differently and that I needed a different type of pillow than I used without the topper. No more neck pain. * I was nervous about this purchase because I've had bad experiences with toppers and mattresses in the past. Sam's Club return policy have me the peace of mind to give it a try, and I am so glad that I did. * I recommend rotating the topper regularly.

Please read before purchasing

We decided to purchase this topper even though a review had warned of the foul smell. Once opened, the awful smell permeated the room. It smells of death and soiled diapers. I do not know how anyone would willingly put this on their mattress. I called customer service to return and was told it had to be picked up. I was told I would receive a call to schedule the pickup. Later that day I received an email with a return label for Fed Ex. IT IS IMPOSSIBLE to place back in original box. My husband had to buy a big box from a storage company to be able to send via Fed Ex. Please save yourself the time and aggravation and DO NOT PURCHASE.
