Added a modification to my 27FB Twin setup. I weekend camp and often have various friends, family, or just the wife and I. Wanted to flexibility to convert the bedroom for different situations.
Enter the convertible Super King 96" x 80" bedroom. Absolutely palatial in size and could comfortably sleep a family of 4 with smaller kids. Easily converts in a couple minutes.
Premise is straightforward.
1) Create a quick release system for center nightstand allowing it to be easily pulled off without tools. I put a few brackets with thumbscrews that secure it down onto it's base.
2) Built some 5/8" planks that are under a twin, that can be pulled across to span the twin bed walkway space.
3) Bought an extra matching foam mattress to create two tightly fitting 36"x20" that can be dropped in place. The bed feels continuous with good support even between the gaps.
Photos probably better tell the story
