I originally bought one to put upstairs in Izzys room ,but put it together and its in the front room - cos its really useful! The top book 'hammock' is quite big and will hold a fair amount of large books - so I have put some of her nicer books that we only read together as she cant reach up there. Then on the middle shelf she has her books she can reach just fine, and then the 3 little boxes are useful for other bits and bobs!
£18 is good price so I just ordered another for upstairs and will keep this one down here
