Spent about $1200 on a Herman Miller chair I bought at Design Within Reach. Totally worth it for the number of hours you spend in it. Go to their store so you can test out a bunch of models. Some models have small medium and large sizes which is really important because a chair for someone who is 5’3 should be a different size than someone who is 6’2

Poppin file cabinet. I bought it from the Poppin site but have also seen them at Container Store.
Herman Miller Sayl chair. Comfier and more attractive than the Aeron IMO.

Ikea Hemnes solid wood series are cost-effective good bookcases.

Ikea office chairs can sometimes fit and support as well as much more expensive Steelcase or other higher-end chairs, but fit is highly individual so try before you buy. Stressless offers very comfortable but rather expensive office chairs: https://www.stressless.com/global/products/homeoffice

Uplift makes good desks with a zillion style and feature options. https://www.upliftdesk.com/

I prefer to have two monitors on the wall and a desk on wheels in the middle of the room. I use a wireless keyboard and mouse. I also have a folding table I can add for more surface area. Storage is against the wall.

We’re looking for better furniture for our home work set-ups… finally upgrading three years into WFH. What home office file and storage cabinets, desks and chairs have you found that work well for you? And are good quality? Thank you!
