A seat that is too deep can create pressure behind the knees.
A seat that is too short may not provide enough thigh support.
That is why seat depth adjustment matters, especially for people who sit for long working hours.
In this video, we use the Hookay SAIL2 ergonomic chair to show how adjustable seat depth helps different users find a better sitting position.
Proper seat depth can provide:
Better thigh support
Less pressure behind the knees
Better fit for different body types
More comfort during long sitting
For brands and office furniture buyers, seat depth is an important feature to consider when selecting ergonomic chairs for different users.
