Recliner cup insert, arm tray or separate base?
Choose by furniture shape and movement.

Built-in inserts
Check the insert’s size, depth and handle clearance. The holder’s published dimensions do not prove fit for your drink.
Arm trays
A tray depends on the arm’s shape and stability. It can move when the chair moves; check the actual accessory and chair instructions.
Steadi on a fixed table
Use a compatible container on a full 5.2-inch supported area. Steadi is a resting base, not a chair attachment.
