Here’s a new one from IKEA Hacker. It’s an adaptation of the Duktig doll bed for use as a sturdy cat bed, designed especially for a slightly hefty tabby, Titina. Titina’s mom Paola bought two cushion covers and sewed them to the correct size to make removable, washable covers for the existing doll bedding that comes with the Duktig. There you have it and Titina loves it!
