The set includes a space cover, a frame, 4 suction cups, and a base. Dimensions: 45 x 37 x 31cm. Easy to install without any tools. This window seat provides your cat with a comfortable and fun space in the house. The specially designed large suction cups are super strong and can hold up to 50 pounds. Before first use, place a heavy object (about 2kg) on the seat for an hour to help the suction cups release tension and stabilize their hold. After this, your pet can use the seat more safely. The hammock cat bed gives your cat a front row view of nature and the outdoors without taking up valuable floor space. Ideal for cats who like to bask in warm sunlight or active cats who need a higher viewing angle. The suction cup is made of PVC material. In low winter temperatures, the material may harden and not function normally. Placing the suction cups in hot water for 5 minutes can help restore suction.
