is it possible to remove the arms if I wanted to go arm-less?

you don't have to install the arms

Is there really a three-year warranty?

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.

What kind of table is this chair suitable for?

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.

I'm getting what perceive to be conflicting answers. Does the chair back lilt with the seat or independently?

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°
