This is our first memory foam mattress. We have had it about a month now. It is very firm which has caused several sleeping problems. Though now it seems to be much better. I am much happier with the memory foam then to spring style mattress.

This is our second purchase of this mattress. Simply the best I have ever had. So incredibly comfortable, firm but soft at the same time. Will not even look at anything else as long as these are around

The mattress is plush with the right amount of firmness. I found it very supportive and confortable to sleep on. I gave it 4 stars as opposed to 5 , because it still has a slight smell after almost a month.

My second foam mattress purchase from Sam's Club, first gel. I have already noticed a better nights sleep in just 6-7 weeks ownership. I have some significant back problems and this mattress has helped ease the daily pain. Try it, you will love it.

We bought one a year ago and we love it!!! We like the ease of setting it up and we just got another a month ago for our guest room!! Very comfortable and nice and cool! The smell disappeared in one day!!

This was one of the most comfortable beds I've ever had. I love it, I used to wake up with my hips being sore and I was always tired, not anymore. I can't wait to go bed.

Our son has significant spinal issues and the conventional mattress we purchased for him did not provide enough support. This mattress supports his entire body very well and helps him sleep through the night.

I bought this mattress for a guest bedroom. It is so comfortable our guests don't want to leave. Haha!! Don't make the same mistake. Use it for your master bedroom!

We started with our Night Therapy 13" MyGel Prestige King mattress Feb 2014. It is now November 2014 and we have returned it to Sam's. Thank goodness for Sam's excellent return policy!! I am 225 lbs and a back sleeper and she is 135 lbs and a side sleeper. The first 3 months of bed use was pleasant. But as time wore on, the indentions for both of us increased to the point we were encased in a hammock shape with a puffy ridge between us. Whether 135 lbs or 225 lbs, this mattress sags over time and stops supporting as it did in the first 90 days. That's what you need to be aware of. And that causes a total loss of the initial pleasant feelings about this mattress. Hope that helps.

I love this mattress. I had really planned on buying another gel mattress which was going to cost triple the price of this one, but when I started to research I found this one and decided to give it a try. I'm so glad I did. From the moment you lay down it feels wonderful. I've had back surgery, and it's really hard to find a mattress that when you wake up that you can get up and not be sore, and stiff, but with this mattress I've not had that problem. I would recommend this to anyone who's had to deal with back issue's like me.
