This is the best air mattress we've ever bought! For some reason, it's not as good as our older one which we just lost after about 5-7 years of sleeping on it every single night; but it makes us happy and it's better than all of the other double-high air mattresses for support and comfort (once we added our 3" foam topper on it!! I'm very picky about what I sleep on. We were never comfortable with regular mattresses and before I bought the Queen Supreme Air-Flow Bed, we had a $2100 Tempurpedic mattress which was nice for about 6 months and even though we turned it twice within that time, it was sinking in the middle and we always ended up sliding into the center of the bed with an unrestful night's sleep. So, when we Gave Away the extremely expensive Tempurpedic, I bought one of these Intex double-high air mattresses that looked like a regular box spring and mattress for close to $200 because I read great reviews about house guests sleeping on it for long, extended stays and how nicely it fit regular fitted sheet sets. We slept on that air mattress for a bit while we were trying to figure out what to do about a permanent mattress. Well, it turned out that we got some of the best restful nights we've had in a very long time on that Intex air mattress and we did for many years because we never did get another mattress! Also, even though it is made out of plastic, it did not have a bad smell like some new plastic items do. The new mattress needs to adjust a bit and allow for the material to stretch for a couple of days by adding a little more air when it settles after use. Then, it all was good. The only time we had to add air was when there were significant air changes either temperature, humidity or pressure, which is fine with us. After using it every single night for about 5-7 years, it finally was losing too much air to keep filling it up to make it through the night, we decided to buy the exact same mattress again! We bought it from Windy City SuperStore on Amazon, and when it came, I immediately filled it up and we slept on it That Night! Unfortunately, the new one wouldn't hold air for a solid night for about a week-week and a half, so I contacted the place we bought it from. They said to contact Intex because they do the warranty replacements. Intex's customer service told me that I needed to cut up the mattress and only send them back a portion of it for the warranty replacement and that it would take up to 10 days to receive it, then fulfill the replacement order and then up to an additional 10 days to get the replacement back to us. I told them we are using it as our sole sleeping mattress and that I cannot go that long without a bed. The Intex rep told me to contact the company I purchased it from to see if they could help, so I did. After emailing Windy City SuperStore, who I purchased the bed from, they didn't understand the practices or advice from Intex, but they said they would immediately ship me a replacement mattress and THEY DID!! I got it just a few days later and this one works GREAT and holds the air PERFECTLY! I was so happy, I gave Windy City SuperStore a Wonderful 5-star rating and I recommended them as an amazon store owner that stands behind their products!! YAY! I'm getting great rest again, sleeping on this Wonderful Mattress!
