From: $575.00

Split foam seat technology seat with added inflatable lumbar support.


The Delta Comfort Duo Office Chair provides exceptional comfort and ergonomic support for the user. This model has a high back rest with an inflatable lumbar pump.

the Comfort Duo range of chairs use a unique split-seat to provide comfort through-out your day. The foam at the back of the seat is softer than the front. This prevents you slouching or sliding forward as the day goes on. The foam padding in the chair has anti-microbial properties.

Fitted with a 3 lever mechanism which allows you to adjust the  seat angle, seat height and back angle. Along with the angle adjustments the seat back is height adjustable so you can position the lumbar support in the right position.

You can choose from three different seat sizes to suit a range of users.

The fabric of the chair can be covered in a standard stretch fabric in black or in the Warwick Beachcomber heavy duty commercial fabric range. Other fabrics are also available. Due to the split-seat design this chair can only be covered in a fabric (not vinyl).
