I have looked for this subject and there are loads of threads but lots of the links don't work.
I have a tall almost 2yr old boy and I don't need it to last forever as he is my last child but then again I don't want it to fall apart straight away! My 5 year old will play with it too no doubt.
There are two different smoby ones in Argos, a few in toys r us but the elc one is too expensive.
The only feature I know I need is at least 2 different sides/areas to it so when 2 kids are plating with it they are not fighting constantly.
Thanks
