Springfree are the best – We had the large round spring free for near ten years and although it was still ok , have recently up dated to the large square springfree , love them !!! We have a son with special needs , who needs to jump , a Lot ! And it’s study and safe for him , he like the sun cover over the top too , although his only complaint would be he can’t play the basketball nets on there with the sun cover on . We hope to always have a springfree, even the customer service has been good and the fellows came and took the old one and set up the new one for us , thank goodness! very popular activity jumping and basketball now with my boys and their friends in the street .
