Mechanism (manual, motorised, lift-assist)
Pull lever or push-back recline, a motor with buttons, or a motor that also tilts the chair up to help you stand.
Why it matters
Manual levers need arm and leg strength to close; motorised stops at any angle; lift-assist helps anyone with knee or hip pain stand up.
What to check
Motorised chairs need a socket nearby and ideally a battery backup for power cuts.
