Hills Supa Fold Mini Washing Line - Beige 1 "Won't stay up" 14 November 2018 The problem with it is it doesn't "click" in the upright position, so as soon as you add some clothes, it collapses over a few minutes. Wouldn't recommend. A note from the team Thank you for getting in touch with us about your Hills Supafold Mini washing line. We're sorry to learn that the airer doesn't click in to place and therefore keeps collapsing. we'll be in touch with you shortly to help.
