I tried an adjustable pillow and have never slept better — here's what happened

Finding the right pillow for your sleeping style and body type can take a lot of trial and error (which can also translate to a lot of unnecessary pillow purchases!). But what if I told you there is one that suits all?
Fill: Memory foam and microfiberBest for: All sleepersFirmness: Adjustable Warranty: 5 year limitedMSRP: from $85 at Coop
We're in the process of retesting one of this year's best pillows for all sleepers, the Coop Original Adjustable in the 'classic' shape, which means I've been sleeping on it for a week now.
Like a traditional pillow, it's aim is to keep your neck and shoulders in alignment with your spine, but you can also customize it to your personal requirements, thanks to it's adjustable fill of cross-cut memory foam pieces and microfiber. So far, I'm impressed by the cushioning comfort it delivers.
With the Memorial Day mattress sales seeing big discounts across all things sleep, including pillows, bedding and tech, not to mention some of this year's best mattresses, so it's a great time to refresh your bedroom set up. If you're considering investing in the Coop Original Adjustable Pillow, read on for my experience.
Coop Sleep Goods is a popular bedding brand specializing in adjustable pillows and mattress protectors that are high quality with a reasonable price tag.
The Original Adjustable pillow comes in three different shapes, the 'classic,' (that we're retesting here) the 'crescent' and the 'cut out.' The classic shape is the brand's most affordable adult pillow, and is available on both their official website and retailers like Amazon.
The MSRP has, however, significantly increased from $59.99 for a queen (when we first reviewed it a few years ago) to $85, while a king is currently priced at $99.
Coop does offer discounts throughout the year during major holidays, and right now there's 20% off their pillows in anticipation of the Memorial Day weekend. This drops the the price of a queen down to $68, which is a reasonable discount, but it's important to note that it's still more expensive than it's previous MSRP (which we had seen discounted in previous sales, too).
Price hikes aside, Coop does offer excellent benefits for bedding, including a 100-night sleep trial (where you can return your pillow for free within 100 days if you're unsatisfied with your purchase), a 5-year limited warranty and free shipping.
Coop Original Adjustable Pillow (classic): was from $85 now from $68 at Coop Sleep GoodsThe Coop Original Adjustable Pillow in the classic shape is available to buy in two sizes: queen and king. The MSRP of a queen is $85 while a king is priced at $99. But there's 20% off inf the current Memorial Day sale, bringing a queen down to $68 and a king to $79.20. Benefits include a 100-night sleep trial, 5-year warranty and free shipping.
The Coop Original Adjustable pillow arrived in a cardboard box, rolled and vacuum sealed in plastic, like the best mattresses in a box. The pillow quickly unfurled once out of the plastic, but it did need to be fluffed up to fully expand.
The brand suggests either allowing a day for the pillow to fully expand or putting it in dryer for 10 minutes to fluff it up. I opted to wait a day, (and did notice some off-gassing during this time but it was not particularly strong), after which it was all ready to be slept on.
The pillow also arrives with an additional bag of fill so you can adjust it, if required, to suit your sleeping preferences.
We reviewed the Coop Original Adjustable Pillow last year, but retesting it was my first time trying out an adjustable pillow, and I was a little skeptical about whether it would be right for me. To my surprise, the Coop Original Adjustable pillow felt perfectly plush, yet supportive. So much so that I decided not to adjust the fill at all.
The feather-like softness and sink-in cushioning of the microfiber and memory foam fill cradled my head and neck well, and I drifted off into a relaxing sleep easily on the first night.
While it's designed for all sleeping positions, I found it almost perfect for me the way it arrived without having to adjust the fill. I'm a combination sleeper but spend most of the night on my side, and the plush feel let me sink into the pillow, but still kept me supported.
However, as an adjustable pillow, you can remove or add fill, there's the option to make it firmer, softer and increase or decrease the loft, which means people with different sleeping styles to me can (as the name suggests!) adjust it to suit them.
I've been sleeping on the Coop Original Adjustable in the classic shape for a week now and I think it's the comfiest pillow I've ever tried. It also effectively aligns my head, neck and shoulders with the rest of my body, meaning no joint or muscle is under particular strain during the night.
On the fourth night, I did adjust the fill by adding more from the bag (about a quarter of the additional fill provided) to see if it made any difference. Despite having a good sleep experience without adjusting it, adding the fill created an even more supportive pillow. It still felt cushioning, but firmer at the same time — I'd say my adjustments changed this pillow from soft to medium-soft.
Throughout the week, I was more than comfortable sleeping both on my back and side with this pillow. I also never felt hot or found the pillow stuffy, thanks to the breathable cover made from Lulltra fabric (a blend of 60% polyester and 40% rayon) and the airflow that the fill allows.
One issue I did have is that the Coop Original Adjustable requires regular fluffing to maintain its shape and support. While I didn't find this severely impacted my sleep during the first week, it's possible my opinion on this may change over time. Stay tuned for the full review of this pillow to find out.
After sleeping on the Coop Original Adjustable Pillow for a week, I think it's an ideal choice for all sleepers, but especially side and back sleepers. Using it as it arrived and adding a quarter of the additional fill provided a softness and subtle support that suited my sleeping style.
While it did not trap heat at any point, at this stage I would say it's better to opt for a dedicated cooling pillow like the Coop Cool+ if you're a hot sleeper or experience night sweats or hot flashes. Read out full Coop Edencool Adjustable Pillow review to find out more.
I need more time to assess the Coop Original Adjustable pillow, and will be reviewing it in full, but based on my first-week testing experience and the vast online reviews (on the Coop site the pillow has 4.7/5 stars from more than 17,000 reviews), I think this pillow delivers on its promises and more.
