Took some time, but dog loves this bed. It is of higher quality than others have bought and the surface material is as advertised.  It is intentionally slightly loose so that dogs can scratch their way in and move it around a bit.  It is very durable and has not been effected by the scratching.  Clover loves to roll on back and side and scratch the surface.  She didn't do it initially but seems to love it now. Washed it twice so far and has held up like new. 

Overall a great dog bed.  The large was a bit too big for our 62lbs dog, but felt the medium was too small.  Would have like it to fit our large crate but it does not match the crate dimensions.  Adjustments to Casper sizes to fit standard dog crates would be a big plus.
