Chair Accessories - Other FAQs
How do I know if a seat cushion is the right size for my chair?
Measure your seat width and depth, then choose a cushion that’s 1 to 2 inches narrower and slightly shorter in depth. For example, if your seat is 20 inches wide and 18 inches deep, a cushion around 18 to 19 inches wide and 16 to 17 inches deep will fit without overhang or knee pressure.
Are rollerblade-style casters safe for hardwood floors?
Yes, high-quality polyurethane casters are designed to be floor-friendly and quiet. They reduce scratches compared to hard plastic wheels. Just make sure your floor is clean of grit and check that the caster stems match your chair’s sockets, typically around 7/16 inch diameter and 7/8 inch length.
What’s better for lumbar support: mesh or foam?
It depends on your preference. Mesh offers breathable, flexible support that feels subtle, while foam provides a firmer, more defined push. If you want gentle guidance, choose mesh. If your lower back needs more structure, a contoured foam lumbar cushion is usually the better pick.
Do I need both a footrest and a seat cushion?
Not always, but the combo can be powerful. A cushion reduces hip and tailbone pressure, while a footrest ensures your feet rest flat and your knees sit comfortably. If your chair sits high or your feet don’t fully reach the floor, a footrest often delivers the biggest ergonomic win.
How can I stop my chair from rolling when I don’t want it to?
Swap the casters for glides. They fit in the same sockets but keep your chair stationary. Choose rubber or non-marking nylon glides with a base around 2 to 3 inches wide for stability and floor protection. It’s a quick, tool-free change on most office chairs.
