Teddy's magic chair

I've had Teddy for 18 months now, and he still is not comfortable sitting on my lap, EXCEPT for when we are at my sister's house, sitting in her recliner.  I'm not sure what it is about the recliner, but it is the only chair in the entire world that Teddy will willingly jump up and sit on someone's lap.  I really have no idea why - it's a nice soft leather, it rocks gently and swivels (which one would think he wouldn't like) and it belongs to my brother-in-law, who Teddy runs from.  I guess it's all part of Teddy's mystery, along with his attraction to my liquor cabinet and his fasination with my cannister vacuum.  Some things we'll never have the answer to!
