Folding Guest Beds - Rollaway Guest Bed on Wheels, Riviera Sleeper

Excellent product. Not only is the mattress extremely comfortable (if you like a firm mattress) but the 2-mattress design will allow it to maintain comfort as it is stored (and not get all lumpy). If you want a spongier mattress then just buy a topper for this. Fits standard twin sheets. We've gained an entire room back in our small house as we just roll the bed away when there are no guests (which is most of the time).The only bummer is that one of the rails that supports the bed in the open position was bent in shipping. It's not enough to affect the stability of the bed and not worth sending back for a new one, but I was disappointed that the thing was a little damaged upon arrival. I blame the shipper though, not the seller of the product. This is a great product and we are glad to finally have a solution that is more comfortable than an airbed and allows us to use this room for the 99% of the time we don't have guests.
