OFFICE CHAIR / 3 VERSIONS

The Gas chair, designed by Jesús Gasca, is one of STUA’s most iconic models.

It stands out for its lightweight aluminium frame, fluid lines and remarkable comfort, thanks to the curve of the backrest and the natural tilt of the seat.

The Gas collection offers two types of swivel chairs:

1) Version with castors — height-adjustable

Ideal for work, offices, collaborative spaces or reception areas.

It swivels freely and allows for precise height adjustment.

2) Self-returning version — fixed height

Perfect for meeting rooms, conference rooms or executive offices.

The chair swivels whilst seated, then automatically returns to its original position when you stand up.

The Gas chair is available with or without armrests, and in several combinations of colours and frame finishes.
