A step-by-step guide to fitting the beige rectangular top bed cushion on your Big Cat Palace, including screw-hole alignment, cushion placement, and common mistakes to avoid.
Quick answer
To fit the rectangular top bed cushion on a Big Cat Palace, first secure the 24 by 17 inch beige top bed to the tree using its two M8 or M10 screw holes, then place the included cushion inside the bed. Check that the bed sits level and the cushion lies flat before your cat uses it.
Why the screw-hole size matters before you start
The rectangular top bed comes with two screw holes sized for M8 or M10 bolts. Before you begin, confirm which bolt size your Big Cat Palace uses at the top-bed mounting point. Using the wrong bolt can strip the threads or leave the bed loose, so check your existing hardware or the tree's assembly instructions first. If you are replacing an old top bed, keep the original bolts handy to match the size.
When to replace instead of add a cushion
If your current top bed is cracked, wobbly, or has worn screw holes, replace the whole rectangular top bed rather than just adding a new cushion. The cushion is designed to sit inside the bed, so a damaged bed will not hold it securely. On the other hand, if the bed is solid and you simply want a fresher look, a new cushion alone may be enough—but this product includes both the bed and cushion, so it is a straightforward upgrade.
Step-by-step installation
- Remove the old top bed if replacing: Unscrew the existing top bed from the Big Cat Palace and set the bolts aside in a safe place. Keep the bolts organized by size so you do not mix them up. Lay out the bolts in order of removal to simplify reinstallation.
- Check the bolt size and hole alignment: Hold the new rectangular top bed over the mounting points and confirm that the two screw holes line up with the tree's bolt holes. The bed accepts M8 or M10 bolts, so verify which size your tree uses before inserting any bolts. If the holes do not align, do not force the bolts—recheck the orientation of the bed.
- Secure the bed to the tree: Insert the correct bolts through the bed's screw holes and tighten them by hand until snug. Avoid over-tightening, which can crack the bed or strip the threads. Give the bed a gentle wiggle test; it should not move if the bolts are properly tightened.
- Place the cushion inside the bed: Set the included beige cushion into the rectangular bed, smoothing it flat so there are no lumps or folds. The cushion should sit fully inside the bed's edges. Press down on the cushion to check it does not slide around; if it does, adjust until it sits evenly.
- Final stability check: With the cushion in place, press down on the center of the bed to confirm the whole assembly feels stable. If you notice any wobble, recheck the bolts and tighten slightly if needed. Let the bed settle for a few minutes before inviting your cat up, and supervise the first use.
