The larger sled is approximately 24 X 56 inches. It has a patch in it, but appears to be holding. My grand children used it this Christmas and it is still holding air. It's quite slow, but because of its size would be great for an adult and small child to go down a hill together, or enough room for two children. It can be inflated with an air mattress pump or something similar and I guess just be blown up by mouth. The smaller disk does have a leak and we did not use it this year. It can probably be patched. Both are porch pick-up or just take one.
