SO FAR - as I’ve only had the Prospe 10” firm gel for a few weeks and then had shoulder surgery. The Prospe 10” gel works really well with my adjustable bed. The firm is just right for not “sinking” to the bottom. I really like the weight of the Prospe 10” gel. My bed is against the wall with only a few inches to work changing the linens. I can lift it (pre surgery) with way more ease than my old tempur pedic XL Twin.
