Furhaven Water-Resistant Replacement Dog Bed Cover - Washable Quilt Top Convertible Mattress for Indoor & Outdoor Use - Dark Sage, Jumbo (X-Large) - Perfect for Large Dogs in Living Rooms, Bedrooms or Patios

This worked out so great!! First for the basics: It's a durable, strong looking cover, it has a zipper that spans a full long and one short side, so I was able to get the folded pillow material in. This one was supposed to be 4 inches thick which yeah it would take 4 inches of padding, even though the side walls are only about three but that's fine. It even came with a carry handle on one of the sidewalls, which I imagine would be pretty handy. So it's like a codura nylon, heavy like a backpack. Great color as well! It's not fover based, soonj don't think it will grad hair and become a big mat, us it is washable and brushable.So if you want a really big suggestion I'll tell you what I did. We were cleaning the house and getting rid of one of the kids twin mattresses because they're all in college now, I can throw away the mattress but they wanted to charge me $50 to throw away the box spring. So what I did was cut the cover off the box spring mattress, and threw away the cover, but the padding was so nice I saved it, the springs I could now drop at the dump with the scrap metal. The padding was so nice I decided to make a pillow out of it. Fold it four times and it comes out about the size of this cover, 30 inches by 40 inches. So I saved the $50, and I made a better pillow than I would have been able to buy for about another 50 or $70!!!So I spent $18 on this cover and I figure I saved myself at least another $60-80!!!
