Ouch! When I get up in the middle of the night and can't see where I'm going I sometimes accidentally kick the cats too.
My Sammi girl hated the bed when I first got her, but I like to encourage our cats to sleep with us. By picking her up and sitting with her on my bed and grooming her there she began to like being on the bed. Now she jumps on it all the time!
Maybe you could sit down with your cat on the bed and pet her, give her treats, and be really sweet to her... then she'll want to go on the bed more often.
