Fold the triangular ladder down to 31.5 by 23.5 by 5 inches and it slides behind a sofa between play sessions. Open it and the frame steps up through three heights of 16, 22 and 27 inches, so the same climber suits a cautious 3-year-old and a bolder one a year later. The double-sided ramp hooks onto the round rods at 5 tilting angles, working as a smooth slide on one face and a climbing ramp on the other, and it doubles as a tunnel roof when leaned against the ladder. Rungs sit 4.5 inches apart along a 21.5-inch bar. Plywood and pine wood carry a rated load of 132 lbs while the whole set weighs 16.5 lbs. Anti-tipping straps and tight joints hold the triangle steady.
