The stated adjustment range should include the measured height at your intended installation point, with any setup conditions explained by the manufacturer. Do not assume that a product is suitable just because its maximum height matches your ceiling exactly.
Some designs require a particular arrangement of sections, minimum thread engagement or additional components, and those details must come from the instructions. Check whether the advertised range refers to one complete kit or several different versions sold on the same page. If you expect to move the tree later, compare the second room's measurements now as well. Avoid adding blocks beneath the base or unapproved extensions above the pole to bridge a gap. The correct choice is a configuration documented for the measured room, not a structure adjusted beyond its intended operating range.
As a hypothetical example, a 240–270 cm adjustment range does not cover a 275 cm ceiling. The missing 5 cm is a reason to select an approved extension or another system, not to place a loose block beneath the base.
