This product is very cheaply made for the price.  I read some reviews and purchased the XL bed since My dog is less than 75 lbs. My dog climbed up on the XL bed (he weighs 52 lbs) for the first time and it cracked along the edge next tho the plastic screw. I had him get off, disassembled it, and will be returning it.  Definitely not worth the money.
