Base is plastic not metal wheels don’t spend and roll as they should on venal plant floor. I’ll use it until it’s unusable then I’ll ditch for a better quality chair.
This chair is horrible it’s so uncomfortable! The head rest is way too short which just pushes your neck forward in a really uncomfortable way. The chair is only comfortable when you lay it all the way back like for watching tv or gaming but it’s horrible for sitting at a desk. I returned it within a week because it’s so bad. Only positive - it’s easy to put together
