You need to ask yourself about your budget. The big players (Koala, Arrow, etc) in sewing furniture will start around $1,000 and more. IF you are lucky! Otherwise, look thru Mission Organization for DIY ideas. Professional grade sewing room furniture is awesome and expensive. They custom make it for your particular sewing machine(s).
talk to your sewing machine dealer. They can quote you. And if you pay CASH, they will likely negotiate a decent discount for you.
