Permitted ceiling surfaces depend on the particular tree and its fixing method. Read the installation guide for the exact model rather than borrowing rules from another brand's floor-to-ceiling system.
Some products require mechanical fixing, some use a specified pressure arrangement, and some need additional wall support. Decorative plaster, suspended sections, sloping surfaces and other constructions can require different consideration. The visible paint finish does not identify what supports the ceiling behind it. If the instructions do not clearly cover your surface, ask the supplier and, where necessary, a competent installer before buying. Do not assume that a soft pad makes every ceiling suitable or that a product described as no-drill cannot cause damage. Compatibility needs to be established for the actual room, including both the ceiling contact area and the floor beneath the tree.
Describe the structure honestly when asking for advice: 'painted ceiling, construction unknown' is more useful than guessing concrete or plasterboard. A ceiling finish can conceal different structures that need different fixing decisions.
