I've had my Koala for about 12 years, & don't know how I managed before. It is made to solve the problems that plague us without make-shift accommodations for sewing surfaces. My husband is quite the accomplished carpenter, but when he saw all the special features of the Koala cabinet, he said he could not reproduce it for that cost.
I don't know my model #, but it has the full top cover that opens to allow for quilting a full quilt, the side storage unit that rolls out for placing an iron/serger/ cutting board to the left of the machine. &, of course., the hydraulic lift for raising & lowering the machine. Good luck !
