Our old mattress gave up the ghost a while back. Now, I like a firm bed for my back and SWMBO likes a soft one. We saw the adverts for the Harvey Norman "Dial a thingy" but a few minutes on Google revealed some very dissatisfied owners. The thing works on a small compressor inflating an airbed to different pressures. Noise becomes a problem in a very short time.
Anyway, an enquiry for a possible solution to our problem in Sleepy's revealed a Sleepmaker bed that can be custom made (at no extra cost) in any of 4 firmness grades on either side. SOLD - her side is a #1 and I have a #3. Purrfek!:2tsup:
It's called a Sleepmaker Select.
Cheers
