I purchased chairs that I love via Robert H. Lord Company in Manchester. They have a showroom where they have many sample chairs and tables which I loved because I was able to go try several out in person. I ended up selecting the chairs on the attached invoice. I love them. Here is the
VS website. I believe my chairs are made in a rolling version and in different sizes. Staff and students love the chairs. I got lots of "My butt is so comfy in these chairs!" and similar exclamations when we first purchased them. Also, pricing, quality, and warranty are great.
Here is my contact I worked with at Robert H. Lord.
Let me know if you have any other questions.
