Our nearly fifteen year old girl needed a bit more comfort as she approaches the golden years.  She's pretty spry for a senior, but would be restless at night (as many older folks are).  This bed solves her problem.  She sinks in without the bed turning to mush, curls up and sleeps for hours and hours (snoring all the way).  Bravo!  Her little pal our puppy Felix can't wait to bunk with her (once he's out of the crate!)
