These are good quality multi-adjustable task chairs that we get in different colors on a regular basis. They are manufactured by Ergonomic Comfort Design. Generally they have height, seat tilt, and back rest angle adjustments, as well as back rest height and arm rest height. We get them in black, grey, red, and several shades of blue. There are some differences in the looks of the pads on the armrests. These go in and out of stock regularly, calling for availability is advised. Sometimes we have a quantity of these chairs come in without room for them inside our warehouse, and we sell them for $30 to $50 each after they have been stored outside, as-is.
