We're sorry to hear about the issue you're experiencing with the stability of the crossbar/footrest on your stool. We understand it may be inconvenient, but we're here to help!
Our footrests come in two lengths. Could you please check if you have received two different lengths of footrests?
Also, please make sure the Phillips screw has been correctly inserted through the footrest and securely attached to the chair leg. In some cases, the wood density can make it a bit tricky to use a manual screwdriver. Don't worry, you can try using an electric screwdriver for an easier installation!
If the issue continues even after trying these tips, please reach out to us right away. We are committed to providing you with the support you need to resolve this matter effectively.
