As a renter this is exactly what I’ve been looking for. The hook-on mount means I can move it between windows in seconds I reposition it every few days to follow the best afternoon sun for my cat and it takes about 30 seconds to relocate. The sewn-in sleeve attachment instead of a zip gives real confidence it won’t come apart during use. The machine-washable cushion is a brilliant practical detail; I’ve already washed it twice and it came out perfectly. The premium hardwood and metal frame construction feel genuinely durable. Highly recommended for anyone in a small space.
