Fred,
The lay flat was not an option when I got mine. It just came standard that way. Pull the pins that hold the back legs on and the ramps lay flat on the floor. Back legs are easy to move as they aren't big and bulky. Carpet for sleeping under the car is something that you have to get.
Also one more word of advise. The ramps are powder coated and if your tires are the least bit wet when you try to back on, they want to spin and go off to the side. I fixed it by going to the hardware store and buying some of that stuff they stick on boats that is sort of grain so you don't slip. Works great. I was at our April Car show a couple of years ago and they had a display there and were trying to get a Superbee on the ramps while the dew was still heavy and it was spinning and wanting to slide. I told them what I had done and they went right to the store and got some of that stuff and no more problem. I think Casaleenie got something and put on his too.
