I purchased a select number sleep bed 3000, a couple years ago and have hated it ever since I got it. The stupid air chambers keep breaking and customer service keeps sending me the wrong parts. What a mess. I would never recommend this bed to anyone. Like other customer compliants, there is a big sinkhole in the middle of the bed and I am constantly waking up in the sinkhole. My back and arms have never hurt so bad. Please do not spend your hard earned money on this crappy bed. I want to throw it in the dump. I can't believe I am still paying for this stupid bed. I spent over 3000.00 on a piece...
