I love these for my dog who can't make it through the night all the time. They are big enough that he can't miss and they are absorbent enough that they don't loose any fluid, they are small enough to fit in my tiny washer and spinner and I recommend them overall!

Bed saver.

I have a small dog that sleeps on the top of my bed. Recently she started leaving a wet spot on the bedding. She has renal failure. So I bought 2 of the 30x36 pads to put on top of the bed. She now sleeps on them, and I JUST TAKE THEM OFF EACH DAY AND THROUGH IN THE WASH. Saves my bedding and bed.

Good underpad

After I had a procedure/surgery and came home, I wanted something to sit on that would not stick to me, or be hot to sit on, or crinkle like paper, and since I was just hours after the surgery that if I was clumsy and spilled my drink, it would soak it up while still being comfortable to sit on so I could relax. This was perfect and has worked very well, it also washes and dries very well. I managed to spill my juice and this pad absorbed it all without soaking through to the recliner I was sitting on, and the pad was very comfortable.
