Here's what Mapex say about the T770A Throne
Playing and sounding your best is about more than your drums. Feeling comfortable and secure while you play is every bit as important. The new Mapex T770 and T775 four point support thrones provide comfort and stability for every gig.
The heavy-duty four-leg design keeps you completely stable and perfectly balanced while playing. The threaded steel spindle allows precise height adjustment from 18 to 26 inches. A memory lock secures your desired seat height so you're completely comfortable every time you play
