Harper ★★★★★ Oct 22, 2026

The MDF frame and base fit together perfectly, and my round bases lock in snugly with no wobble during movement. I picked the taller frame height to match my bases, and it makes ranked formations look clean on the table.

Amelia X. ★★★★★ Oct 21, 2026

I was worried my 40mm round bases would wobble in a ranked formation, but these MDF frames sit flush and the lower base keeps everything aligned. The two-piece design makes assembly straightforward.

The frame height options let me pick the perfect depth for my 40mm bases, and the whole thing clicks together securely in minutes. It's a solid, no-fuss way to get round-based units moving in ranked formation.
