## Questions & Answers

**Q: is it possible to remove the arms if I wanted to go arm-less?**
A: you don't have to install the arms

**Q: Is there really a three-year warranty?**
A: Yes, our chairs come with a three-year warranty, and you can contact our SIHOO team customer service with any problems with the chairs during this period.

**Q: What kind of table is this chair suitable for?**
A: The armrests and seat of the chair are adjustable, and the height of the armrests from the ground is within the range of 24.8 inches - 28.7 inches, I hope this will help you to choose a table.

**Q: I'm getting what perceive to be conflicting answers.  Does the chair back lilt with the seat or independently?**
A: The seat does tilt back as you recline the back. However, it doesn't tilt at the same rate.  Reclining the back all the way (back 30°) tilts the seat back by about 5-10°

The chair is amazing. After lot of research, I landed on this one...and the choice was spot-on. Lumbar height is adjustable and even the seat depth is adjustable. I just got a cushion on top of this for my sciatica and have been extremely comfortable on it...best option ever...

### ⭐⭐⭐⭐ Not so bad
*by T***R on 2 November 2025*

Assembly instructions were actually good and it wasn’t too painful. Quality is ok. Doesn’t feel luxurious but it works.

### ⭐⭐⭐⭐⭐ Excellent build
*by F***Y on 4 December 2023*

I was a little concerned that i would struggle with the build of the chair. It was very well thought out by company including providing gloves to use. This comes in handy when using the provided screwdriver to tighten all the screws. One issue i did was was the casters are difficult to put in. However once i aligned the caster so that it was straight i was able to use my what to whack it...a bit painful on the hand but the chair is so strudy that its worth a 1 minute discomfort. Worst case let one of your kids do that part. All in all happy with the comfort of the chair and the setup of the head rest which is quite flexible. Super comfortable and the color (i purchased the grey one) is very nice a little change from black.
