Direct answer: place the furniture on the flattest suitable area, assemble it exactly as instructed and use every required wall or ceiling fixing. Carpet does not replace structural anchoring.
Check the floor beneath the pile
Look for uneven boards, thick underlay, rugs and grippers that let the base rock. Never add an improvised platform unless the manufacturer approves it.
Test progressively
Press the base and each level before access, then observe the first supervised climbs. Re-tighten only as the manual permits.
Recheck after movement
Vacuuming, room changes and repeated jumping can alter position. Stop use if the unit leans, twists or develops loose joints.
A practical furniture note: The Ultimate PawHouse can support this routine where its current specifications suit your cat and room. Product furniture cannot diagnose or treat a health or behaviour problem.
