If it were me, I'd go to Sam's club, get 2 of the nice fluffy dog beds, and a couple of little pillows for their heads and ahve them both sleep on the floor.  That way, you and dh will sleep better and they'll be just as comfy on their beds.

Our bichons sleep on our old pillows, and our minpin in his crate (he is a sleep-peer- he used to sleep on our bed wiht us, but he would stand up in the middle of the night, PEE and lay right back down. I don't know if he even knew he was doing it LOL.  But he STILL does it and I have to wash his blankets every day (what can I say, he likes fresh linens!).
