FAQs

The M56 fits users from 155 cm to 185 cm tall. Seat height adjusts from 43 cm to 52.5 cm, the seat is 50 cm wide and 40.5 cm deep, and the backrest lifts 6 cm so the lumbar pad meets your lower back. Overall height runs from 103.5 cm to 125.5 cm.
The M56 is rated for users up to 136 kg. The mechanism uses a cold-rolled steel tension spring and a double-lever explosion-proof plate, and the chair itself weighs a light 12.5 kg.
The butterfly-shaped lumbar pad flexes with you as you move and slides 3.5 cm up and down to match your spine. The double-lever mechanism adjusts both lift and recline tension and locks the backrest at any angle between 90 and 135 degrees, so you can hold a light lean for reading or a deeper recline for a break.
Seat height 43 to 52.5 cm; backrest lift 6 cm; lumbar pad 3.5 cm up and down; headrest 7.5 cm of height with 45 degrees of rotation; armrests 7 cm of height; recline lockable anywhere from 90 to 135 degrees; 360-degree swivel on PU castors.
Allow around 15 to 20 minutes for one person. The chair ships flat-packed with all bolts and an Allen key included, so no extra tools are needed. At 12.5 kg it is one of the easiest SIHOO chairs to unbox and move on your own.
Every M56 carries a 3-year warranty with full parts coverage. If a part fails under normal use, contact SIHOO Australia and we will send a replacement part at no cost rather than asking you to freight the chair back.
Orders are dispatched the next business day from our Sydney, Melbourne, Brisbane or Perth warehouse and usually arrive within 1 to 3 business days. Delivery is free Australia-wide.
The M16 and M57 fit users from 150 cm to 190 cm; the M56 suits 155 cm to 185 cm. The M16 is the simpler sibling with fixed armrests, a 90 to 125-degree recline and a 150 kg rating. The M57 moves to a full-mesh seat with 3D armrests, a deeper 46 cm seat and a 150 kg rating, and suits people who want maximum airflow. The M56 sits between them: a soft W-shaped foam seat, height-adjustable armrests, a flexing butterfly lumbar pad and an infinitely lockable 90 to 135-degree recline, rated to 136 kg.
