(I have never put bedding in the crate until chewing stage is over.) My dog is using Gingers bed that I purchased from Drs foster & smith 11 yrs ago. It is as thick as a regular human bed and has heavy duty washable cover on it. It is still in the condition it was 11 years ago, and Ginger slept on it a lot. He loves it.
