we will be shortly doing up our spare room for our toddler, but we would like to also use the room for guests as it is a double and were thinking of buying a sofa bed or airbed. I need something very comfortable and am prepared to spend quite a bit. We have used airbeds but hey always go down over night and i find them cold, my SIL has a really posh one with springs in it apparently which I need to check out. What do you lot do ? I want to get this right and for guests to be very comfortable.
