Very flimsy wooden support struts which havent been properly bonded so started to separate and split. The bed bows in the middle so we both fall outwards towards the edge of the bed, on top of all this all the moving metal parts squeak terribly with the slightest movement despite resorting to WD40, On the positive  side we have a very prompt reply from wayfair who have agreed to fully refund, just waiting for our refund now.
