Here you can purchase extra logs for your tree seat / planter. Buying one unit will buy you three logs, which is one tier, but there's no limit to how many tiers you can add. It is advised to purchase these at the same time as your tree seat. Each tier will raise the level of the seat by approx 3.5" (about 9cm).
