This is the Eidfjord Slatted Mattress base frame (link to product below). All you need is a Queen mattress on top.

I ordered the wrong size by mistake and cannot return without a trip to IKEA Vancouver. The product is untouched and still in the box so selling for the list price. You save tax + shipping. Must be picked up. Based by Hillside Mall
