Basically we wanted to buy a Brimnes bed from Ikea, and after a year of ummming and arrring about this we went through the trauma of going to Ikea, but all the Queen Brimnes bed bases were out of stock. We made our own version. We did buy some cool fabric from Ikea to help with the guest mattress storage.
Step 1: Attach legs
Chuck your ensemble base on its side. Uncrew old bed legs. Screw in new bed legs. Carefully put flip yourbed horizontally again (this is a two person job).
Step 2: Use your storage
The one advantage of not being restricted by proper drawers (like Ikea's Brimnes bed), is that you can choose to store long things...like a wedding dress.
