I can certainly agree with the OP’s assessment of the current state of the mattress industry. We had a Serta king that was causing much pain and suffering. Inspired by Ken Hightower’s mattress rebuild videos, I undertook a DIY rebuild using Arizona Premium components. Serta Rebuild The rebuild has been mostly successful over the past year or so, although the hard foam surrounding the pocket coils has begun to break down. Ken Hightower suggested replacing the pocket coils with latex, which we’ll probably do in the not too distant future. The old Serta foundations are sagging with the heavier weight of the latex and will also need to be beefed up or replaced. A DIY mattress rebuild can seem like a daunting task, but in reality isn’t too hard even for an old duffer like me! Hope your Simmons turns out as well as our Serta.
