Would've got 5 stars, except...
Ordered Thursday. Web site promised next day delivery, only to be dissapointed by confirmation e-mail which then said the following week, Mon to Weds. Called Wayfair customer services on the Weds to be told that delivery not yet booked in!!
All credit to Customer Services...who chased courier (XDP) and got back to me within the hour and had arranged for next day delivery.
TIP: If assembling in a small/box room, unpack all the parts and lay them out elsewhere where you've got lots of space. Assemble the underbed first. Took about 3hrs for 1 person assembly.
