G'day Sarah,

The Heavy Duty Folding Step folds flat when the legs are swivelled all the way up. They are 8.5cm thick when the legs are folded in.

G'day Sally,

The larger of the two sizes is when the step is open and legs extended (they extend out at an angle). The smaller of the sizes is with the legs tucked in at their shortest length.

G'day Keith,

The minimum height of the Wanderer Heavy Duty Folding Step is 18.5cm and the maximum height is 24cm. 

G'day Sarah,

These are a brand new product for us and we haven't received our first delivery of stock yet, so I can't actually answer this one for you. These are due around mid-December. Keep an eye on the site for the little green "in-stock" flag on these and if you still need an answer once we've got the stock I'm happy to fold one up and send you a few pictures.
