This review is specifically about the wool filled dog bed inserts by Molly Mutt. I love the idea of their wool dog beds, and I loved this bed when it first arrived. I'm really sensitive to materials and wanted to make a healthy choice for my dog, myself, and the environment, and I am willing to pay good money for it. I scoured the internet to try to find the perfect bed for my needs. Sadly, I'd never buy one of these beds again, and can't recommend it with gusto to my health and eco-conscious friends. We've had it for about a year and a half, and as I was just sitting here pulling apart the clumps of wool (again), I was inspired to write a review. The wool became clumpy really quickly, and I literally ripped open the seam to get to it so I could pull it apart and fluff it up again. I'm going to be sewing a zipper to the insert so I can get to the wool more easily. Wool sheeting may work much better than this clumpy stuffing. When I phoned to ask about it, I was told I need to do exactly as I'm doing (minus the ripping of the seam, but I just couldn't get to the material well enough without ripping the seam to get my hands on the wool clumps). When it gets super clumpy and uneven for my poor dog, I put several layers of blankets on it so it doesn't feel as bumpy. Especially as he ages and his joint health declines, this will not be the bed for him. It's possible that if there were more wool in a smaller envelope this wouldn't happen as bad, but as it is, there is enough room that the clumpy wool spreads out leaving some areas bumpy and other areas sparse, so much so that the heavier areas of my dog's body (the hips for instance) would nearly hit the floor. I feel bad making a less-than-stellar review because I LOVE this company's vision, but for the cost of this bed, I'm pretty bummed at the need to repeatedly do the physical task of ripping apart the stuffing on a regular basis. The top cover is made fabulously, it's just the wool insert I'm really unhappy with. If the company is going to tell us to pull apart the wool, they should at least make that easy to do with a cover that allows easy access, but I'm pretty bummed to be needing to fix a bumpy bed in the first place, especially at this price point.
