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.

Say goodbye to neck pain
Color: White, Size: Queen
This is a very good product but it takes some time to adjust removable stuffing to accommodate individual sleeping patterns.

Soft and comfortable cooling pillowcase that gets the job done!
Color: White, Size: Queen, Color: White, Size: Queen
I got this quilted bamboo pillow protector (queen size) because I wanted a cleaner, cooler layer between my pillow and pillowcase since I’m always hot. This has been a great solution for that.
The fabric feels soft and smooth, and it doesn’t make that crinkly noise some cooling pillowcases do. I’m a warm sleeper and the “cooling” aspect feels more like breathable than icy-cold, but it definitely sleeps more comfortably than the thick polyester protectors I’ve used in the past. The light quilting adds a little cushion without making my pillow feel bulky or changing the loft much.
I like the fact that if you use a memory foam fill pillow you can add or remove some of the filling to make the pillow as firm or mushy as you want. This is especially helpful for people that are side sleepers vs people that need more neck support.
The zipper is a big plus. Just be careful when zipping it open and closed as these are usually the first point of failure for pillowcases in my experience. It closes fully and keeps the protector snug so it doesn’t shift around inside the pillowcase, and it gives me peace of mind for sweat / oils and everyday wear. I’ve washed it and it came out fine with no weird shrinking, and the stitching still looks clean.
For the price, it feels like good value if you’re trying to extend the life of a nicer pillow while keeping the sleep surface soft and breathable. It’s one of those small upgrades you don’t think about much once it’s on, which is kind of the point. It just works and helps me sleep more comfortably.
