The Grand Sequoia is made from extra heavy duty cedar lumber and it is built to last! It has 4x4 posts and fort supports so it"s very sturdy. There are three ways to reach the 5" high play deck: a double-wide solid rock wall, a standard step ladder, and even a challenging rope ladder. The Grand Sequoia also has a 10" wave slide that is smooth, safe, and has a fun bump in the middle. Underneath there is a tire swivel swing and there are two belt swings plus a two-person glider. This swing set is a ton of fun and will stand the test of time.
