    Coop Home Goods Eden Bed Pillow Queen Size
    Team Name: Eden, Size: Queen, Color: Classic
    I am very satisfied with the Coop Eden Bed Pillow. It is clearly a high-quality product that is well worth the investment. Here are a few reasons why I highly recommend it: Fast Shipping & Great Packaging: The pillow arrived very quickly. It was packed beautifully in a box that was both aesthetic and very functional. Initial Scent , There was a slight 'new pillow' scent upon opening, which is totally normal. I let it air out for a few hours and it was completely gone. Fully Customizable Comfort: The pillow itself is incredibly comfortable and looks great. The best part is the ability to add or remove fill to reach your exact preferred loft. It even comes with an extra bag of fill, so you can make it firmer or softer depending on your needs. Being able to determine the exact volume is a game-changer. Easy Maintenance: It comes with a lovely outer cover that is removable and washable, which is a fantastic and practical feature. Overall, you can really feel the quality of this pillow. If you are looking for a customizable, premium sleeping experience, this is definitely the one to get!

    Amazing pillow - adjustable filling
    Team Name: Eden, Size: King, Color: Crescent
    This pillow is AMAZING. My wife loves it. The crescent shape is cool and unique and enables your neck, back, and shoulders to lay better on the bed. My wife is a back sleeper and sometimes side sleeper. What’s amazing about this is you can adjust the quantity of the filling to your preference. It came with an extra bag if you want to fill it with more. We ended up taking a fair bit out. The card it comes with was super helpful illustrating how your head should rest on it, which showed my wife she had to take some out for her neck to be flatter. It seemed too firm at first so taking out the filling helped. The material inside is super fluffy, light, and airy- it’s extremely soft! As soft as down or other material. I mean this is an amazing pillow. It is luscious and super comfy. It is expensive but worth it.

    I can't sleep without this pillow.
    Team Name: Eden, Size: King, Color: Classic
    This review is for the King size, adjustable Eden pillow. I bought the original years ago and somehow lost it when I moved recently, so I bought the Eden to replace it. Years ago, these pillows were not adjustable but I loved it anyway and was truly upset when I discovered it was missing. I actually lost sleep over it. When I found out they're adjustable now, I about lost my mind over the possibilities. In fact, I love the adjustable, Eden version so much that I bought another one. So yeah, I have purchased this pillow 3 times and have not been happier with any other pillow. Bad news first. The odor. You should know that they claim the foam is packed "fresh." This means there WILL be an odor when you receive it because it hasn't had the opportunity to air out. You'll have to do that yourself. Maybe they'll find a way in the future to "pre-air" the foam they use. For now, just accept that it's WORTH THE WAIT and really not a big deal. Don't return your pillow just because of the odor. It WILL go away and you don't want to miss out on this fantastic pillow. They suggest letting it sit for 24 hours or throw it in the dryer. Neither of these methods are long enough, in my opinion, but please be patient. I have experience with 3 of these pillows now and tried different techniques. This is what works best for me: Upon arrival, I immediately remove the outer pillowcase and set aside. Over the course of 48 hours, I let it sit on the bed in my guest room with the ceiling fan on and I "fluff" it 3 or 4 times each day. (I will describe proper fluffing technique for shredded foam later) Then I throw it in the dryer on low for a full cycle. Then put the case back on and it's done! You'll never have to worry about that again and soon you won't even remember having to do it. Now that THAT'S out of the way... I love that these pillows are adjustable now. They really packed in the foam on the king size! I'm not kidding. There was so much foam in my pillows that they, frankly, were too heavy and way too firm for me. I've seen some negative reviews to the contrary. Maybe since then, they've increased the amount of foam they include (they should keep that up, if that's what happened). That's not how I like my pillows but some folks might be into that so I'm glad they put enough in there for those who need a lot of support. They do include 1/2 pound of extra foam in case you want a true, solid-as-a-rock feel. I do not. I'm a stomach and side sleeper, who likes more "squish" to my pillows, so I ended up removing so much foam from my 2 king size pillows that I have enough to make 2 standard sizes with the same squish factor. Not kidding. I went to the Coop website and purchased 2 standard liners and cases that I'm going to stuff with the excess foam and use on my guest bed. I anticipate some of my guests asking where I got the awesome pillows. :) As we all know, memory foam holds heat too well and some foams will kick you right out of bed because you just can't stand to be that hot anymore. I did experience heat retention in the "original" that I had for years. I flipped the pillow over to get the cool side. I assumed all memory foam was like that so I put up with it. I don't get that at all with the Eden version. I'm a hot sleeper but I haven't had any issue with the Eden at all. The Eden has the blue foam in it that's gel-infused. I don't use anything extra or fancy to keep them cool. The foam is in the provided liners and pillowcases and I cover those with normal, cotton pillowcases. I did see a couple reviews that claim their pillows went flat after a while. I'm confused by this. I had my first pillow for years and never experienced any change in texture. As with ANY shredded memory foam pillow, they need to be "fluffed" every now and then. In fact I fluff all of my pillows occasionally, regardless of the stuffing used (I have a variety of textures on my bed). But regardless, shredded memory foam pillows don't go flat. It's just not a thing. If you feel like it's flat, fluff it. Get rough with it. The shapes of the shreds can, over time, start to fit together like puzzle pieces and can become compact in some areas in the pillow. Maybe this is what creates the illusion that it's flat? "Fluffing" a shredded foam pillow involves breaking all the pieces up so they can move independently again. To achieve this, you have to grab several areas of the pillow with both hands so you have clumps of foam in your hands and then sort of jostle everything around in there, breaking up all the chunks. I usually grab and use the same motion I would use to bang cymbals together and then repeat all over the pillow until it feels like everything is separated again. I find this technique to be most effective when I grab around the edges. This takes only 5-8 seconds to accomplish and is completely normal maintenance for a shredded foam pillow. Final thought: Shredded memory foam pillows are not for everyone because comfort is subjective. We all sleep differently and have different needs. After reading through some of the negative reviews, I've determined that some of them HAD to have been left by people who have never used a shredded foam pillow before and have determined it's not for them. COOP has a generous 100 night, no questions asked refund policy, so it doesn't hurt to try it. I don't view those reviews as a poor reflection of this company's products, but rather that the consumer tried something once and decided shredded foam pillows are not for them. I do have some experience with shredded foam pillows and can tell you that the Eden is, hands down, the best and highest quality that I've found on the market.
