Auctions can be a great place to find inexpensive sewing room luxuries. Take a look at this dirty drab brown worn chair.
These Herman Miller Sayl chairs are comfortable. The arms lower pretty far and will not get in my way when sewing. They have adjustable lumbar support and are curved just right to support my back and hips. Brand new these Sayl chairs including the tilt, height adjustment, lumbar support, and tilt lock brings about a $700 price tag.
First a brisk cleaning with soap and water. Second tightening loose arm rest bolts. Then, a little upholstery fabric in a cheery color perks up that boring chair.
My total cost (not including the tools) for this $700 chair was about $30. Score!
