What are the seat dimensions? I found the Woosh 3 to be too small for my 18 month old.
Officially there are no measurements available. However, if the Woosh was too small for your 18mo, then don't get this one. Even with some changes to the design, the seat hasn't become much roomier, much different. So if you need something for an older toddler and space is a priority, I would go for something a bit larger.
