Product Description

Ergonomic Benefits of an RH Logic 300


The RH Logic 300 ergonomic office chair has a medium height back with a contoured shape and the added benefit of an adjustable rake to the seat back. This will allow more precise setting of the back angle to personalise the chair which can then be operated in free float mode to achieve the maximum ergonomic benefits from this design.  The backrest shape tapers slightly toward the top, encouraging the shoulders into an open posture and giving freedom of movement and flex in the shoulder joints.  This will promote deeper breathing, circulation and can help to relax tension created in the shoulder and neck muscles.

The RH Logic 300 ergonomic office chair has an inflatable lumbar pump which can be added for maximum lower back support. This will allow the user to individually set the degree of back lumbar support needed.


The standard seat cushion of the RH Logic 300 ergonomic office chair will be comfortable and supportive for most users.  However one can specify an XL seat with slightly larger dimensions giving an extra 20mm width and an additional 40mm seat depth.  Options for the seat cushion also include a coccyx cut out and memory foam for the optimum in pressure relief. 


The RH Logic 300 footbase is supplied in silver grey aluminium with the option of black or polished aluminium. Carpet castors are fitted as standard.

Customer Reviews

RH Logic 300 Review
"I just wanted to drop you a line to thank you all your patience with me and supporting me to get the right chair. Currently I am working really long hours and can definitely feel the difference the chair is making."
Star Rating 5
"I had been advised by healthcare professionals to invest in an ergonomic office environment. Fine Back Furniture listened to my health issues and provided excellent, considered advice. I found the personal set up service extremely helpful and reassuring. I have now been using my chair and desk for a month and am very pleased with the results."
Star Rating 5
"I have been using the chair for a month or so and I am no longer experiencing any of the health issues I had with my old chair - back, neck & wrist ache and a feeling of physical tiredness at the end of the day. It was wonderful to be able to try the new chair for a week before purchase. The set up was excellent not just setting up the chair but the whole work environment."
