Wood effect chest of drawers - with saggy bottoms (Harringay N4)

Wood effect chest of drawers (L67cm x H93cm x W41cm).

All of the drawers have been overfilled in the past and so they are coming away at the backs.
Tape has been used to try and fix on three of the drawers.

I have seen 'furniture/draw wedges' that may help to fix the sagging, and apart from this issue, it is otherwise in decent condition.

Collection is from a first floor flat above a shop on Green Lanes N4 - it's on the main road and there is no parking directly outside.
