Minky X Wing Airer £5.00 at Sainsburys using click and collect. Or £8.95 delivered.
Next cheapest I can find is £16.99 at Dunelm.
The Minky X Wing Airer is a steel airer with a strong tubular construction, ideal for drying laundry indoors. It unfolds from flat to fully extended in a single, simple move. The arms can be secured horizontally for drying delicate "dry flat" items, or at varying angles for drying longer items.
In addition to its 14m of hanging space, the Minky X Wing has corner slots for hooking up clothes hangers for drying shirts. It folds flat for easy storage behind a door, in a cupboard or under a bed.
