The RH Logic 400 is perfect for both remedial and preventative back care solutions, as well as 24/7 applications.

Based on the unique 'two-point principle' of upright posture and active sitting, the chair improves breathing and circulation, and stimulates the muscles. The one to one tilt action ensures that lower back support remains constant, whatever position the user sits in.

The RH Logic 400 has a high backrest and comes as standard with lumbar pump, seat slide, castors for carpeted floors, base in graphite aluminium and Gaja fabric.

The RH Logic 400 can also be enhanced with optional extras including armrests, extra large seat, neckrest and coccyx cut out seat.

We also offer a free chair set-up by one of our ergonomic consultants with this chair to help adjust the chair to your workstation and needs. To find out more read our Free Chair Set Up Procedure below in the delivery and returns section.

Very comfy chair that suits my needs.


Excellent build and service. They came out as agreed and on time to set up the chair for the individual with no problems.




Exactly wat my back needed! Superbly adjustable and can be tailored to suit the individaul, I like the fact that the seat height can be elevated "above standard" mass market chairs.


The employees who I've had to purchase these chairs for are already showing lessening signs of back issues. Don't know why we never had these chairs from the off.


Exactly what we wanted and very easy to adjust and control for the end user.


Fit for purpose


Excellent quality


I thought the product would be a bit easier to work i.e. then I want to change the posture of 1 piece of the chair I have to reset the entire char - nothing locks until you use the twist action at the under of the chaire - not very well designed there. otherwise I like the chair and my back is happy with the huge amount of work I do at the desk with my chair
