My baby wouldn't sleep in his bed and I think it was because we had let him nap on our bed which was soft and cozy and the pnp mattress was soooo hard/firm. He did not like it at all....
So our "indulgence" was buying an organic sheeps wool mattress topper for him: the day we got it - he FINALLY slept 6 hours straight! He loved it. It's still firm enough for safe-sleeping but added a little extra comfort. I got it on etsy (http://www.etsy.com/shop/turnanewleafdesigns).
Did you have a baby indulgence item?
