Lucy has 2 beds,
1st is the one in the bedroom. It's an inner spring crib mattress, wrapped in orthopedic foam, with a heavy cotton cover (Mom sewed it, she's really good). Lucy's been sleeping on this for several years and it's the best we've tried so far.
Bed #2 is new this summer, basic large (giant?) Cooleru with a foam pad with cover(thanks Mom, she does love the grandpup). The cover is really important 'cuz while cleanable and comfortable and breathable, the mesh material stretched in the cooleru frame is slippery and Lucy had a very had time getting in and out. This settup is light weight, portable and even breakes down for travel. It's her outside bed on the back porch, she prefers it first thing in the morning when she can lay in the sun there.
Her favorite place to sleep is the lawn in the back yard, she'll follow you around and beg till you let her in the back.......... .............
If anyone needs pics let me know. I can take some later today
