Okay, I know this has just about nothing to do with cooking except that you need to be well-rested to cook well . My husband and I are ready for a new mattress. We're considering the "sleep number bed" model 7000 from Select Comfort. We've read the posts at epinions.com but are curious to know if anyone has experience with this type of mattress (air plus viscous foam). We have a local store to deal wtih , so it wouldn't be an Internet transaction. Any thoughts?
