I bought the SIHOO Doro C300 Ergonomic Office Chair in late November 2023. It came very well packaged and was easy to assemble. Once in use I found it very comfortable and I was impressed with the solidity of the chair.

Unfortunately, in February I found the left arm had failed at the joint of the arm rest and contacted Sihoo to see what they could do. I received a prompt response requesting further information about the failure, which I answered with a short video to show the problem.

They immediately came back with a promise to replace the whole arm, which I received a few days later. Replacement was easy, requiring 2 bolts to be unscrewed and re-fixed.

During this period I also queried an issue I had when I first got the chair - the chair lift movement was a little restricted and did not work well with my rise and fall desk. I had to maintain the desk at its lowest level and the chair at its highest.

The answer was a suggestion to find a replacement gas lift that met my requirements and that they would put £25 towards the replacement.

After careful measurement I found a replacement gas lift for £21 and ordered it. I had a refund of this almost by return.

When I came to fit the new gas lift I found the original was fully stuck in the chair feet 'spider'. I tried a pipe wrench and a sledge hammer but could not remove it. Sihoo sent me a replacement 'spider' and I refitted the chair feet and the new gas lift - took me under an hour to complete.

Now the chair is working fine and I have movement on both the chair and the desk to be able to find a comfortable position.

During this experience Sihoo answered all my emails promptly and gave every assistance. The whole issue was cleared within half a month, including the deliveries.

I have been very pleased with there response I received from them.
