Vacuum packed mattresses shipped to your door in a box used to be a novelty. Now, they're a commodity.
This mattress from Signature Design by Ashley is well reviewed, made from three layers of foam like a lot of the more expensive brands, and is on sale for just $149-$264 depending on the size, complete with free shipping. Even if you're happy with your current mattress, at these prices, this could be a great upgrade for your guest room, if you don't mind your overnight guests staying in bed all day.
