Have 5 of these in a home office and have been very pleased. They get heavily abused by kids and have held up very well. Also very comfortable!. Steven. Boston, MA. Mon Mar 24 2025

Have this chair at work (with headrest) so ordered for my office at home now we’re working from home more. It’s very sturdy and comfortable. Good lumbar support which was the primary reason I spent the money - I knew what I was getting for the price. Noticed an immediate difference with my sciatic pain. Assembly is very easy - no tools just attach the base to the seat. The thing I like about this chair is you can lean and the arms lean with you. Also the arms are adjustable.. Sandy. Aurora, IL.

Create a distinguished workspace with the handsome Collin office chair. The exposed natural oak wood arms and brushed gold base offer an airy element while paired with heather ivory tweed performance fabric. Performance fabric is moisture repellent, durable and easy to clean. As wood is an organic, porous material, these pieces will contain natural variation of texture and may also exhibit fine indentations and cracks. Wood pieces will also display a disparity of colour and grain, and visible knots and burls that add to the character of each piece.

I’m very happy with it. It’s gorgeous. Kimberly. Calgary, AB. Wed Apr 22 2026
