The "magic cube" comes in a red envelope, the black soil is zipped on with a zipper on three sides. The two times three square slabs (edge length 64 cm, 7 cm thick) in dark blue are laid out in less than 1 minute. The three squares are related zigzag. The two head portions of the slabs are also connected by a seam. With a velcro strap on the foot, the slabs are secured against slipping, either single layer in approximately 1.30 m wide or a double layer with a single-lying area. After use, they fold almost goes back to the cube and are stowed away in the reference again. Everything is meticulously crafted! - I slept well on it!
