a first platform, the first platform including one or more panels defining a first walking surface and a pair of spaced first side rails, each first side rail having an interior edge that faces the interior edge of the other first side rail; and a second platform, the second platform including one or more panels defining a second walking surface and a pair of spaced second side rails, each second side rail having an interior edge that faces the interior edge of the other second side rail, wherein the second platform is slidably coupled to the first platform and the second platform is adapted to be slid relative to the first platform between a storage position and an extended position such that, in the storage position, at least a portion of the second walking surface overlies at least a portion of the first walking surface in a direction that is normal to the first walking surface, and in the extended position, no portion of the second walking surface overlies the first walking surface in the direction that is normal to the first walking surface and each interior edge of the first side rail is substantially collinear with an interior edge of a second side rail. |
