As a friend and I were napping on a rock at Berger Park, we came up with the perfect sleep product: Rock Mattress (TM).

From the original Rock Mattress would evolve the following:
- Futock, perfect for poorer-than-average college students
- Hammrock, bowl shaped rock tied between two Redwoods
- Outdoor Sleeping Rock, survivalist camping bed consisting of two stone slabs
- Cock, a small folding bed, popular with the military
- Memory Stone, lava bed that molds to the contours of your spine
- Lazy Rock, for that special grandpa who likes to keep one hand in his pants
