How do I compare usable cat furniture size rather than photos?

Compare usable size by requesting or checking the measurements of the surfaces and openings the cat actually occupies. For a bed, distinguish the sleeping area from its outer frame; for a den, compare internal room and doorway dimensions; for a cabinet, separate external furniture size from tray space. Product photos can help you understand shape and layout, but lenses, perspective and the pictured cat's size can distort your impression.

Look for a measurement diagram and confirm the relevant variant. You can then compare those figures with your cat's ordinary resting posture or a bed it already uses comfortably. A paper outline may help visualise a platform without assuming that total area alone determines comfort. Keep access and capacity in the comparison too. A generous-looking surface is not a useful sleeping place if the cat cannot reach it comfortably or the documented limit does not support the intended use.

The same distinction applies beyond towers: Velvet Nest’s bolsters reduce the area inside its overall bed size. Compare the space within the raised sides with the cat’s resting outline instead of treating the outside rectangle as the sleeping surface.
