We're trying to make one big purchase a month to get our house to where we want it.I think that I've decided that I want a new mattress to big the next purchase, so that we can put our current mattress set in the guest room. That will pretty much round out all of our furniture purchases and let us focus on doing outdoor projects.I've heard of a lot of places having good sales right now, but where's the best place to get an inexpensive, but durable and comfortable mattress? I really know nothing about mattresses.
