Our 100 pound Black Lab is getting up there in years, and we wanted a supportive but comfortable bed for him. After trying several other brands and not being satisified, we found the Rainer Napper Bed. It’s far softer, and more supportive, than other beds we've tried, with bolstered sides that support our dog’s head, not flop over. In a nutshell, very well constructed. And also very attractive-- lots of people have already asked where we got our dog bed! Our dog started using it the very same day we received it. Now the only problem is that our cats also find it mighty comfortable, and sometimes take it over, with the dog, who is such a gentleman, lying down beside it, and given the cats baleful looks. So glad we found this bed!
