Quality & Comfort with Fully Adjustable Support
Team Name: Eden, Size: Queen, Color: Classic
I used to buy pricey, handmade, 100% down pillows—until I learned about the cruelty behind down production. I stopped using down entirely: pillows, comforters, jackets, everything. Then began the long search for something that could at least come close to the comfort of down, I tried Tempur and countless others, but nothing came close.
As a side sleeper, I need a pillow that’s high, SOFT, supportive, conforming, and huggable. After wasting money on at least five different pillows, I finally tried the Coop Home Goods Eden Pillow because of its adjustability. The cover is kind of thick, soft, and well‑made (I use a nice cotton pillow cover over it). The filling is soft and high quality. You can customize the height and firmness however you like. It even comes with plenty of extra fill.
To my surprise, the shredded foam doesn’t make the pillow clumpy—something every other similar pillow I tried struggled with. The surface stays smooth and soft, and it’s been a total game‑changer. It’s a keeper! I’ve had mine for almost four years now and only needed to add more filling once, about 8–10 months ago. Toss it in the dryer on low with a couple of tennis balls, and it fluffs up like new. And the icing on the cake: outstanding customer service.
I highly recommend this pillow and will definitely buy it again

Nothing like the original Eden, don’t buy the name
Team Name: Eden Cool+, Size: King, Color: Classic
I’ve had the original Coop Eden for 5+ years and it has been a great pillow, very comfortable, soft but supportive but when I purchased a new mattress I wanted to refresh my pillow and saw the Eden Cool+ and wanted to give it a try. I figured it could only be better than the original Eden…but it is not. While the outer cover is noticeably cooler to the touch, it is not soft like the Eden. Also, this cool material mostly gets negated if you use a pillow case anyway. The shaped fill material I would also say is “lumpier” for lack of a better word than the shredded material in the original. The combination of the harder, less supple outer casing and the lumpy material just aren’t a good combination. I will say it does sleep slightly cooler than the original Eden but not enough for the sacrifice in comfort. I would absolutely consider going back to the original Eden.

Unmatched Pillow with Unmatched Customer Service!!! 5 STAR ALL AROUND
Team Name: Eden Cool+, Size: King, Color: Classic
## A Dream Come True (and Customer Service to Match!)
From the moment I first laid my head on the Coop Eden Cool+ pillow, I knew I'd found something special. It's truly a game-changer for hot sleepers like me. The "Cool+" technology isn't just a gimmick; it actually works to keep my head and neck comfortably cool throughout the night, leading to the most refreshing sleep I've had in years. The adjustable fill is brilliant, allowing me to customize the loft perfectly for my sleep style, which means no more waking up with neck pain. The support is fantastic – it cradles my head without feeling too firm, and it holds its shape beautifully.
However, what truly elevates my experience to a full five stars, beyond the exceptional product itself, is the **dedicated and outstanding customer service**. I had a minor issue with my initial pillow (a rare manufacturing defect, which can happen with any product). I reached out to Coop Home Goods, and their response was nothing short of phenomenal. They were incredibly prompt, empathetic, and went above and beyond to resolve the issue swiftly and completely. They genuinely cared about my satisfaction and ensured I was left with a perfect product.
It's rare to find a company that not only produces a superior product but also stands behind it with such integrity and genuine concern for their customers. The Coop Eden Cool+ pillow is an investment in your sleep, and knowing that you're backed by such an incredible customer service team makes it an even easier decision. Highly, highly recommend!

Cariloha pillow cover replacement
Color: White, Size: Queen
I have a queen size Cariloha resort pillow and the zipper on the cover broke. This replacement is SPOT on and fit perfect. Material feels comparable to original very pleased.

The fabric feels soft and noticeably comfortable against the skin
Color: White, Size: Queen
This is a zippered pillow protector made from a bamboo/polyester blend with a quilted surface. I’ve been using it for a few months on a standard queen pillow, including regular washing and everyday use. It’s also been exposed to dog hair, which I’ve been able to manage by vacuuming the surface.
Pros
The fabric feels soft and noticeably comfortable against the skin
Breathable design helps keep the pillow from feeling overly warm
Quilted texture adds a bit of cushioning without changing the pillow’s shape
Zipper closure keeps the pillow fully enclosed and secure
Holds up well after multiple washes
Vacuuming the surface works well for removing pet hair
Cons
White fabric shows dirt and hair more easily between washes
Slightly thicker than a basic pillowcase, which may not suit everyone
Bamboo blend feel is smooth but not identical to 100% natural fabrics
Bottom line:
For me, this has been a comfortable, low-maintenance pillow protector that holds up well over time, especially useful if you want something breathable that can handle regular cleaning and pet hair.
