The individual pieces were either wrapped or boxed to minimize the risk of damage, with tough cardboard in between the main sections of the chair. While most of the packaging can be removed by hand, having a pair of scissors on hand will make the process quicker and easier. Save Up to $1,200 on the Samsung Galaxy S25!

First, we attached the silver spokes to the core of the wheelbase after removing the protective plastic sleeves. These were secured using the washers and screws provided. Next, the casters were firmly pushed into place by hand: this step requires some effort but doesnt involve any additional tools. After this, we inserted the hydraulic piston and covered it with the accompanying sleeve.Moving on to the seat section, we assembled it separately and attached it to the wheelbase. Constructing the armrests was the next step, which involved using multiple screws and washers. Once the armrests were complete, we connected them to the backrest and secured everything firmly. The headrest was the final component to be attached, with a decorative cover bearing the Sihoo logo added to conceal the screws where the headrest is mounted.PreviousNext1 of 7PreviousNextIn total, assembling the chair took approximately one hour.
