A fir wood sandbox that closes up like a small cabin: the canopy runs down all four sides, a zip door rolls up and ties back, and mesh windows keep air moving while the sand stays shaded. Two built-in benches measure 24-in each, lift open for shovels and molds, and carry up to 155 lb so an adult can sit down at ground level. The frame is bottomless over a 57-in by 54-in liner, keeping sand separated from the soil below. It takes 661 lb of sand across a 48-in footprint and meets ASTM and CPSIA standards. Assembly is required.
