The Discovery wooden playsets fort is 5'x 5'(deck floor) and rests approximately 5 feet off the ground. It's designed for children under the age of 12 and can support over 250lbs! LUMBER NOT INCLUDEDAll-bolt construction (no nails to work lose), patented bracketing system, 4x4 framing and other strengthening features are used to insure the strongest sturdiest 'Build-it-Yourself' playset. Anchor rods and/or supports are never needed with Plan-it Play kits. The Discovery's dimensions are 17'wide x 8'long x 10'high (17'x 13'x10' with slide). A six foot safety-zone perimeter is recommended around our playsets (3 feet minimum). The ladder steps are wide and flat designed around our powder-coated 14 gauge brackets (hardware included). Our swing belts and chains are 'extra-duty', near commercial grade, and are plastisol coated to prevent pinching of the skin or fingers. Each kit has an easy to follow 3D illustrated manual which includes a lumber purchase/check sheet.
