Do I need White Glove Setup or can I do it myself?
- The chairs are simple to setup. It only takes about 20 minutes. The only reason setup is required is because most chairs ship with the arms detached to make it narrower, lighter and easier to move into your home.
- The setup is basically just screwing the arms to the chair. It includes easy to follow instructions and does not require special tools or skills. There are also wheels on the bottom of the chair to make it easier to move.
- If you want them to setup the chair inside your home, please select the option for “White Glove Setup”. We don't recommend it for most people it because it's an easy way to save yourself the money. But we're happy to add it to your order if you'd like.
