Ok! So Ron's post on the slatted bed base from Ikea got me thinking. We like the ETI mattress and think it is of good quality, but a little harder than our Sleep-Number (my number is 55). A little more give would be nice. The other day I was near an IKEA, so I checked out the Lonset Slatted Bed Base. The full size is 75"X53" and I studied the construction to see if I could modify the bottom right corner to fit the mattress on our 21. I saw where a 2X4 (actually finished at 1 1/2 X 3 1/2) cut at an angle would fit nicely into the corner and allow support for the slats to be shortened in that one area. So, I bought one and brought it home. $77.00 with tax.
I modified it today, installed it, and will test it out camping the next two days. It is very sturdy, very well made, and fits nicely in a 21. It actually consists of two identical slatted bases, each 26 1/2" X 75". They lay side by side. In addition to cutting out the corner, I shortened the left one by 5" to better fit into the rounded left front corner of the bed. The right one was left full length, with the corner cut only:
