This swing set it’s made with very good materials & therefore it’s very sturdy! My kids who are 9, 8, 6, & 3 all plays on this! The sand feature is a bonus as I feel the kids like to explore, dig, and create on their free play time. Everything works very smoothly and just the overall construction of it is very kid friendly thought out. It took my husband and I half a day to build it as we are very slow people :(. But it was very worth it!!
