Keeping a small record can make later maintenance much easier. Save the product name, order date, assembly diagram and care labels in one place, along with photographs of any identifying numbers.
Note which cushion belongs on which platform if their sizes are similar. When a part wears, these details help the supplier identify the correct replacement instead of relying on a photograph of the assembled tree. You can also record any manufacturer advice about cleaning or inspection, especially if it differs between components. Avoid turning the record into a rigid schedule that ignores actual wear: a heavily used scratching area may need attention sooner than a rarely used bed. The purpose is to preserve accurate information and make a sensible repair possible, not to assume that an item remains sound simply because it was checked on a particular date.
A useful folder can contain four files: the order confirmation, assembly manual, care-label photos and a labelled picture of the complete tree. Add written supplier advice if it changes how a particular part should be maintained.
