HÅG H05 5100 (low back) Ergonomic Office Chair

Price as configured: £485.00 Ex VAT £582.00 Inc VAT

The H05 collection rocks. Literally. All the chairs in this collection follow the ‘balanced rocking’ theory - that being able to rock backwards and forwards safely in your chair boosts oxygen and blood-flow by reducing pressure on the intervertebral discs in the back.

The H05 5100 is the first model in the collection, offering a simple and affordable ergonomic chair ideal for office work. The 5100 is partially upholstered with a low back available in two colours - black, or navy. Desk workers will love the simplicity of the chair’s functions, which can be controlled with a simple lever. Adjust the seat depth, back height and seat tilt to create a chair perfect for your own body. This chair will keep you active and help with your posture to reduce the risks of injuries, aches and pains.

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 handle on the front right hand side of your H05 5100. Turn the handle clockwise to adjust the seat forwards. Turn the handle anticlockwise to adjust the seat backwards. About four fingers width between the front edge of the seat and the hollow of the knee provides good blood circulation.

Q: My HÅG H05 5100 low back chair didn’t come with a neckrest – can I order one to add on myself?

You can retro-fit a neckrest to your H05 5100. You will have the neckrest back bar and a large screw in handle. Slot the neckrest into the back bar and tighten with the screw handle. Slot in the neckrest pad and adjust to a comfortable position.

Q: How do I adjust the back angle of my HÅG H05 5100 low back chair?

On the bottom of the backrest there is a handle you can pull outwards to adjust the height. Once you have found the correct position, simply let go of the handle.

Q: How do I stop the rocking motion of my HÅG H05 5100 low back chair?

On the left hand side of the seat there is a small handle. Pull the handle out to unlock the tilt motion. Simply push the handle in to lock the tilt motion.

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

There is a ring style button on the lower back of the backrest. Pull the ring out to adjust the backrest height to a more comfortable position. Let go of the ring style button to lock the backrest.
