We got two of these rugs about 6 months ago for each side of the master bedroom bed.  Both people and dogs tended to slip on the wood floor when getting in/out of bed and the non-slip backing really helped with safety.  They are also small enough to fit in the washer and are durable enough to withstand multiple washings when the muddy dog feet make a mess.  We liked them so much we got 2 more for the guest room bed.
