I want to buy a garden slide for my 2 year old grandson, when he comes to stay. It will be an Easter present. He is the eldest of 3 (currently) grandchildren, and I want something that will last, but that he will be able to use independently- with some supervision. Baby slides are too small, so looking for a toddler/ medium sized one. Current front runners are Feber medium, Smoby medium and Little Tikes folding slide. Any recommendations or alternatives to offer? Thanks in advance.
