The RH Logic 400 is one of the best ergonomic chairs on the market. Often surpassing their 10-year guarantee (or 5 years with 24-hour use), the RH 400 is a long-term investment into your productivity and comfort whilst working.
The RH Logic 400 chair has many add-ons and is easily adaptable. Whether you’d like extra lumbar support or need a coccyx cut out this chair has you covered.
One benefit is that this chair can have individual parts swapped over rather than replacing the entire chair.
It’s very similar to the RH Logic 300, however, the RH Logic 300 has a smaller backrest and lighter mechanism. We would recommend the RH Logic 400 for average to taller individuals and the smaller RH Logic 300 for petite individuals.
Overall the RH Logic 400 is a great chair that works perfectly in both home and working offices. It’s been designed with people and productivity in mind and gets the blood flowing around the body as you work.
Please be aware this chair is being discontinued soon! Quicker delivery time when ordering in fabric Gaja Black or Navy with arms and black or silver base (7-10 days). Other fabrics and specifications will have a 4-6 week wait!
