You can buy a teapot stand from specialist Chinese teaware retailers, Gongfu tea shops, and established online tea stores, but the most important considerations are the stand's size, stability, material, weight, and compatibility with your particular teapot.
A tea tray is usually better for a small home tea setup because it provides a compact brewing platform that can sit on an existing table, while a Chinese tea table requires more dedicated space and is more suitable for frequent or elaborate tea sessions.
A teapot stand is primarily designed to support and elevate a teapot, while a tea coaster protects the surface beneath a cup or smaller vessel; you do not necessarily need both, but they can serve different purposes in a complete Chinese tea setup.
