DH put our kitchen chairs together from2 sets. An oak set and a 4 task chairs with casters and base from Walmart. Dirt cheap for $10.00 a chair. Caster bases are not cheap. We've had these for about 8-10 years. He took the legs off the oak and put the caster bases on them. they even have the hydraulic lifter. I have one in the sewing room and use a couple cushions. I also sew standing up once in a while. the chairs probably cost us all of $200.00 when you consider we used two sets. So not bad price and I don't sit for hours on them. being able to adjust the height helps.
