After years of sleeping on ultra expensive top name brand mattresses, box spring, foam, combination, pillow top, adjustable bases, etc., NONE have compared to the extreme comfort of the Purple mattress. Now with chronic back and hip issues, the Purple is the only mattress that offers me totally pain-free sleep. I no longer toss and turn - no need to readjust my position. I have had the bed for a month and am still amazed that I awake pain-free and well-rested. That combined with the ease of delivery and assembly make this bed simply perfect!
