My mattress is 8 years old and is as lumpy as anything you can possibly imagine. Most nights I toss and turn trying to convince myself that I’m not hangin of the edge of a cliff as my body tries to roll to the centre! I can’t afford to replace it and would love your help in getting a new one. If only they weren’t so expensive! Please help me, I hate to beg but I haven’t slept for a week!
