We have a queen size pillow top mattress bought in 2003 with a two year old 3″ memory foam pad on top. It’s recently developed two large canyons where we sleep, and our bodies are unhappy every morning when we wake up.
We want to replace it, but I’d really like to wait until we move to a bigger space to do that so we can keep this one as a guest bed. Can we extend the life of this one somehow? Or should we suck it up and buy a new one now? If we should buy, any recommendations on what/where?
