Can you fill this stuff sack with cedar bedding?

Answer by Chewy • Jun 25, 2018
This zipper mesh bag can be filled with cedar bedding, old clothes, pillow, blankets, or towels.

Will the stuff sack stand up to a chewer without an extra cover?

Answer by Chewy • Apr 27, 2023
This mattress maker is made of 100% nylon and is durable. However, a determined pet can chew through this material.

Would shredded memory foam get throughthe sack?

Answer by Chewy • Dec 26, 2021
This sack can be used with old dog bed stuffing.

Great Wash Bag

I don't use it to store clothes or as bed for dogs. I use it to put in my dog bed/cushion so I can wash it in the washer machine. Less mess in my washer.

Thinking about the waste we often create

The reason I love Molly Mutt is its a company that cares about waste and sustainability. The covers are so well made. I also love the idea the separate net pouches

The reason I love Molly Mutt is its a company that cares about waste and sustainability. The covers are so well made. I also love the idea the separate net pouches they sell to fill with old pillows, clothing or in my case an inferior stuffing from ANOTHER terrible dog bed. It avoids waste to a land fill.

outstanding

It's exactly what it says it is and it is perfect for the job. And beautifully made. I can't really show it to you because it is full of the stuffing that goes

It's exactly what it says it is and it is perfect for the job. And beautifully made. I can't really show it to you because it is full of the stuffing that goes inside the fabulous dog bed pillow my mom made 20 years ago. If the pillow cover needs to be washed I just take the stuffed stuff sack out and wash the cover but I could probably wash the stuffing in the sack if I needed to.

Just what I needed

I stuffed this with shredded foam from another bed that had a hole in it. Then put the stuff sack into the Molly Mutt duvet cover. The doggo loves it! The cover

I stuffed this with shredded foam from another bed that had a hole in it. Then put the stuff sack into the Molly Mutt duvet cover. The doggo loves it! The cover matches the room it's in and seems sturdy so far.

Great to put the stuffing in

These are great when you want to wash the bed but need to take the stuffing out so it fits in the washer. I do 2 loads, one for the cover, and another for the stuffing

These are great when you want to wash the bed but need to take the stuffing out so it fits in the washer. I do 2 loads, one for the cover, and another for the stuffing and have like new beds again. I’ve had no problems with the zipper nor the material and have used these for yrs. I raise Standard Poodle’s both bigger and small and these sacks hold up fantastically

Great quality and great idea

I purchased this to go along with the duvet cover. Also purchased from this site and also left a review. This bag is much better quality than the bags that come

I purchased this to go along with the duvet cover. Also purchased from this site and also left a review. This bag is much better quality than the bags that come already stuffed into pet beds. This is also great because you can stuff it with items such as your clothes that gives your pet a sense of comfort because they can smell your scent. Great idea I now have 3 of them for 1 dog in separate parts of the house.

My dog chews up his beds. I was able to use the stuffing from the old beds and fill up this sack. Combined with the covers it was a perfect solution and he has not

My dog chews up his beds. I was able to use the stuffing from the old beds and fill up this sack. Combined with the covers it was a perfect solution and he has not chewed up either (yet).
