We had a Cal King airbed also from Sam's but this airbed did not worked for us. We replaced it with this Cal King 13" Night Therapy Gel Memory Foam made by Zinus and we couldn't be happier. This bed supports my back, waking up in the morning with very little or no pain. My wife loved it as well. We have exactly the same bed in a queen size for about 3 years that we slept from time to time and we were always delighted so we decided to get rid of the airbed and we're glad we did. This 13" Night Therapy Gel Memory Foam bed is very much appreciated!

Very comfortable. It's a little more firm than I thought it would be. I have lower back issues, this thus far has been the most comfortable mattress I've ever had. Even my husband loves it. He has RLS and I can't even tell anymore. Delivery was a breeze.. Came straight to my door, easy set up. Suggests that you wait 72 hours before sleeping on it.. We slept on it the first night. I recommend this product 100%

The mattress seems to be of high quality and being 13"s thick looks good on the bed. The only drawback that I have is that it is not firm enough, it was stated as medium firm and I would call it medium. Looks like it will last a long time; overall was a good purchase.

I have never owned a memory foam mattress before but after reading all the reviews I decided to try this one and I'm so glad that I did. It turned out to be one of the best purchases I've ever made. I absolutely love this mattress and I can't wait to go to sleep on it every night.

I bought a queen size in 2013 and loved it but had to give it away when I moved cross country. Just got my new king size here and it's still fantastic. You can't go wrong with this bed. It forms to your body like a glove and I wake up feeling like a million bucks.

I was pleasantly surprised at the support and softness! It doesn't seem to be hot which I was worried about. The only thing I don't like is that moving positions is harder than the innerspring mattresses I've used my whole life. It went back to its original shape very quickly (5-10 minutes). It had an Oder but nothing serious. I waited the 72 hours before sleeping on it like recommended (although it was torture!) and by then I couldn't smell anymore Oder! Now the waiting game to see if it lasts! Fingers crossed!!! (Owner for a week)

Very comfortable

This mattress is very comfortable. But it is very heavy over 100 Ibs.

I would say the product is good overall. Though it says firm it was too soft for us

This is by far the best $600 I have ever spent... This is such a comfortable bed.. The negative comments are crazy!!!
