Product review (3 stars): Adequate, but far from perfect.
These are perfectly adequate for what I plan to use them for...  to keep major dirt and bug-marks off of my washer and dryer while being stored.  However, they are not "perfect."  The "quilted" part is ONLY the top surface (covering the top flat area of the machine and a generically-shaped "console" region).  The sides and front are simply sheet plastic (pretty thin) and there is NOTHING at the back of the machine.

The "zipper" feature allows you to keep these covers on the machines full-time and simply uncover the top areas for use...  and that's clearly how these are intended to be used (not as "storage covers" but rather as "machine in use covers")  This is great if you have a washer and dryer which both open to the top, but not helpful at all if one or both of your machines open to the front.

The "quilted" region (top only) is sufficient to protect the top from scratches if, say, you sit other items atop of your washer and dryer when not in use, but it's not thick or heavy, so realize that this provides very limited protection.

These are inexpensive, and probably won't last for terribly long (especially if exposed to the elements, or even to direct sunlight) for any length of time.  But, for what I'm using them for, they're sufficient.

Just realize, if you want a full-coverage padded cover (for moving and storage) these really aren't what you're looking for...  and you'll likely spend a LOT more for something like that.

One final note...  there are multiple colors available, but the seller I purchased from provided no means of selecting color-of-choice.  I wasn't really picky here, but some of you will be.  I recommend contacting the seller FIRST, before buying, to ask them about this, if you care.  The seller CLAIMED that I could "enter color preference into the order comments" but I was given no such option...  so I got whatever they wanted to send me (which were, thankfully, the same color...  two black pieces).  The seller really ought to do better in this regard.
