Compare the flower tree's usable sleeping area, complete footprint, route between levels, load information and maintenance requirements. These details determine whether the furniture will be useful after the initial appeal of the design.
Check whether the petals or cushions are removable and how they should be cleaned. Look beneath the flower in product photographs to understand the supporting connection, then consult the assembly guide for required fixings. Scratching areas deserve attention too: a decorative stem may provide only a short section of accessible sisal. Think about your cat's normal stretch and preferred scratching direction. Finally, check the availability of replacement components and the seller's current delivery information. An attractive design can still be a sensible purchase, but a clear practical specification helps distinguish a suitable piece of furniture from a photograph that simply looks right.
Count usable resting places rather than decorative flowers alone. A small flower used as a stepping platform may not be a sleeping bed, and its presence should not inflate the number of cats you expect the tree to accommodate.
