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.

FAQs
Q: How do I adjust the back angle of my RH Logic 400 chair?

There is a row of 3 buttons on the right hand side of your Logic 400. Lift the middle button to adjust the backrest angle. Release the button to lock in place. The angle should be set so that your back makes contact with the backrest.

Q: My gas stem seems a little stiff – is this normal?

Sometimes, over time, the gas stem can become a little stiff when trying to adjust the height. A quick and easy fix for this is using WD-40 or Vaseline. Apply a light layer of grease to the gas stem, then try adjusting the gas stem 3-4 times. The gas stem should now adjust easily.

Q: Can my seat slide forward?

There is a row of 3 buttons on the right hand side of your Logic 400. Lift the button furthest back on the right hand side. About four fingers width between the front edge of the seat and the hollow of the knee provides good blood circulation.

Q: I have lumbar support in my backrest, how do I adjust this?

On the back of the RH Logic backrest is a lumbar pump. Use the pump to inflate the lumbar support to optimal comfort. If you need to deflate your lumbar, simply push the button on the pump.

Q: My RH Logic 400 chair didn’t come with a neckrest – can I order one to add on myself?

You can retro-fit a neckrest to your Logic 400. Simply remove the small plastic tab on top of your backrest and slot the neckrest in.

Q: How do I stop the rocking motion of my RH Logic 400 chair?

There is a tilt lock on the right hand side of your Logic 400 at the back. Turn the handle clockwise to lock the chair. To unlock, simply turn the handle anticlockwise.

If you want to adjust the tension of the tilt motion, use the front handle under the right hand side of your seat. Turn anticlockwise for firmer tension and clockwise to loosen the tension.

Q: We have hot-desking and I want to adjust the backrest height – how do I do this?

On the bottom right of your backrest there is a grey handle. Simply pull the handle upwards to adjust the height of your backrest. Once you are happy with the position, push the handle downwards.

Q: My seat has become worn over time – can I just swap a new one for the old one?

Yes, swapping the seat pad is simple. Once you receive your new seat pad, pull off the old worn seat pad. You will notice there are holes underneath around the edge of the seat pad. Simply align these to the seat shell, then push down on the edges to secure the seat pad into place.

wonderful chair and top customer service
This chair is wonderful. It feels so good to finally have a chair that fits my body and won’t exacerbate my back pain. The chair set up was really well done and the consultant was extremely helpful and knowledgeable.

outstanding
This chair gave me instant relief for my neck pain /trapped nerve.The chair makes sitting a pleasure and supports your every move.The movement that enables the back of the chair to move forward with you is incredibly supportive .This chair has to be tried to be appreciated.I believe if I had had this chair earlier I would not have had my neck condition.

Excellent ergonomic chair
I have previously suffered with back and neck pain, (partly work related, but mostly due to having two young children!). As well as receiving physio work, I changed my work chair to an RH Logic 400. It's an extremely comfortable chair and I found the main benefit was being able to sit in the chair for long periods of time without any discomfort. At Posturite, we aim to practice what we preach, and as such I also have a sit-stand desk (which I try to use for at least an hour everyday). Combined with a better chair, my back pain is much better. I also can't stress enough how important it is to get your chair setup correctly by an expert! Now if only we could develop a product to stop my kids being a "pain in the neck"!
