I bought a twin Serta Terrace Heights set at a major retailer. It was delivered last month and I am still within the 30-day forced sleeping period. I say "forced" because within the first week the pillowtop was compressing and I thought sleeping on the floor would feel better but felt I had to give it a try. I couldn't understand why the compression was happening but now that I've done some reading about pillowtops, I understand this is a common problem. The compression appears to be permanent and, at the rate it's going, I should be sleeping in a deep hole before long. I am not overweight.
I need some advice about what to do. I need a good night's sleep and can't keep waking up in pain. I am leery about getting the mattress replaced with something else that will end up being a problem.
If it's my blog you've been reading, you will also know that the only material available that will provide the comfort you sought when you bought the pillowtop, is latex. Unlike the polyfoam and/or memory foam in your pillowtop, latex does not compress. Latex provides superior comfort that lasts.
That said, the mattress you want to buy to put under your latex topper is a firm non-pillowtop model. Look for one with as little memory foam as possible. No memory foam would be best, but there aren't many of those available. Two inches of soft Talalay Latex will provide all the comfort you want and a firm mattress will provide the support you need.
Over the 30+ years I've been in this business, Serta has always made a third rate product. You'll want to change brands. Once you tell me what you have to work with, I'll be happy to direct you to something of better value. Here is a link to the latex toppers. They can be purchased on-line.
