I have had back issues my whole adult life. I slept on innerspring mattresses, which no matter how good only seemed to last about 5 years before my back would start acting up again. It took an episode in the 90’s when I got out of bed on my knees and I had a back spasm so bad that it forced me face down on the floor and had to call 911 for the paramedics to pull me up so I could go to the urgent care. That’s when I first started looking at air mattresses and found Sleep Number (known then as Select Comfort). I have had that mattress for 20 years and during that time it worked well, but I decided I wanted to either update my mattress or buy a new one. My wife went to Steep Number, it was going to cost us $5,000 to $6,000 for an equivalent replacement, and just replacing parts was going to be around $3,000, plus the sales people at the store had a bit of an attitude that was off putting. Instead, we purchased a foam mattress with adjustable bases (package deal and on sale) from one of the big box stores. After sleeping on them for only a few nights we knew that was a BAD choice, for my back and my wife couldn’t stand the out gassing of the foam and the mattress covers are very thin almost like t-shirt material. However, we do like the adjustable bases they came with and decided we definitely wanted an air mattress to set on them. As my wife being one to search for a good deal, stumbled upon the Personal Comfort website and after several hours / days of, talking with the sales team, watching comparison videos, and reading testimonials we decided on the A7 King Flex-Head Mattress which is less than just replacing parts on our old mattress. We ordered the mattress on a Friday, the confirmation e-mail we received said it could take up to 20 business days and would arrive no later than a month after ordering. Well, the mattress arrived the next Friday and we were very excited to put it together and try it out. As I was unboxing the mattress I was very impressed with the overall workmanship and quality of the materials. My wife wanted to watch the videos for putting it together and me being, well a man, charged ahead and of course had to undo and then redo some of the steps, okay several of the steps. The only negatives we experienced was my wife went to move the gel foam comfort layer and it tore where the split was at the head of the mattress, she called customer service and they have a new one coming our way, no questions asked other than for my wife to provide a picture of it. Next was zipping in the split area, it takes a lot of patience and finesse to get through that area, but we were able to do it successfully. Third was the remotes are reversed, so the left remote pumps up the right side and the right the left side, I don’t consider this much of an issue and just swapped the remotes left to right. We slept on the bed for the first time and we both agree, this is far and away better than our old Sleep Number bed, in fact, I have so much confidence in this mattress that I already got rid of our old mattress. I still need to dial in my sleep setting, but I got it fairly close already. I used to recommend Sleep Number, but now will only recommend Personal Comfort, great company, great sales team and great service after the Sale. Patrick and Debra - Tucson, AZ
