Is the Mercer a dual motor or a quad motor chair?
Quad. It has four motors in total — back, leg, headrest and lumbar. Some retailers describe it as dual motor because they only count the lift and recline motors.
What sizes are available?
Petite (136kg, 45.7cm seat width) and Standard (158.7kg, 50.8cm seat width).
What colours are available?
Saddle (brown) and Eclipse (charcoal / black).
Will it fit a smaller room?
The Mercer has the smallest footprint in the Theorem range — 81.2cm wide in Petite and 86.4cm in Standard. Still allow clearance behind for the backrest to recline.
What is the extended footrest for?
It extends further than a standard legrest to support the full lower leg and feet — useful for taller users or anyone elevating their legs for long periods.
How is the chair controlled?
A USB hand wand attached to the side of the chair.
What does delivery cost?
Delivery and installation are quoted per order — the price depends on your address and access. We confirm the cost with you before dispatch. There is no free-delivery option on the Theorem range.
How long does delivery take?
Around 7–10 working days to most North and South Island addresses. Allow an extra 2–3 working days for rural delivery.
Can you take the old chair and packaging away?
Yes — two-person delivery with installation, assembly and packaging removal is available. It’s quoted with the delivery.
Is there a warranty?
Yes. Frame 5 years, chair mechanisms 3 years, and electronics, handset & cable and fabric 2 years.
