TechRadar Verdict

The Cozy Earth Silk Pillow may well be the best pillow I've ever tested. It's filled with mulberry silk, which is a superior silk with longer strands, making it smooth and soft to the touch. The pillow’s shell is made of bamboo viscose, which adds another layer of sumptuousness. Since it’s so plush, the pillow has a mid-to high loft, which makes it best for side and back sleepers.

Cozy Earth Silk Pillow: two-minute review

I’m always on the hunt for the next great pillow. I’ve tested dozens of high-end bed pillows, and several were very good. However, the Cozy Earth Silk Pillow may be the very best pillow that I’ve ever tested (it’s definitely in my top five). I love thick, plush pillows, and this one falls in that category. However, it’s the reason why this pillow is so thick and plush that impresses me: it’s made of mulberry silk.

Now, silk in general, is a soft and luxurious material. But mulberry silk takes this experience to another level. I’ve tested mulberry silk pillowcases and head scarves that reduce hair frizzing and dryness. I also have mulberry silk pajamas that are also luxurious and tend to wrinkle less. And my mulberry silk sleep eye mask is smooth and cooling.

But how would a pillow with silk filling perform? Marvelously. The 100% mulberry silk filling is both strong enough to be durable, and soft enough to feel like I’m at a 5-star hotel. And the bamboo cover is also smooth and soft to the touch. While the pillow is soft, it also provides enough support that I avoid waking up with aches and pain. It works well for back and side sleepers, but may not be ideal for stomach sleepers.

I tested a pair of the Cozy Earth Silk Pillows for over two weeks to see how they compare to the rest of the best pillows on the market. And if you really want to elevate your sleep comfort to another level, check out our guide to this year's best mattresses for all budgets.

Cozy Earth Silk Pillow review: price & value for money

  • Luxury pillow with a premium price
  • 100-night trial period, 10-year warranty
  • Currently 20% off

At $299 (currently on sale for $239.20) in the standard size, the Cozy Earth Silk Pillow is absolutely a premium pillow – and it’s at the top of that category as well.  However, this long-strand mulberry silk pillow is like the crème de la crème of pillows. I wouldn’t recommend it if you’re on a budget, but if you’re prepared to splurge, it’s definitely worth considering.

The king size pillow is regularly $349 (currently on sale for $279.20). Cozy Earth also makes a Bamboo Down Alternative Pillow for $115, and a Bamboo Down Alternative Body Pillow for $195.  

Another one of the best pillows I’ve ever tested is the Purple Harmony Pillow, which combines a honeycomb-patterned GelFlex grid over a latex core. It’s a super-squishy pillow that moves when I do, and has temperature-regulating features. The pillow comes in a low, medium, and tall pillow height, making it ideal for any type of sleeper. The pillow, which should only be spot-cleaned, is $199.

If you prefer a down pillow, the Casper Down Pillow has a multi-chamber design. The outer pillow consists of ethically-sourced 80% white duck down, and a 20% feather outer chamber. The inner pillow consists of 60% white duck down and 40% feather inner chambers. This provides an ultra-soft experience, similar to sleeping on a cloud, but also thick enough to be supportive. The pillow is cool to the touch, machine washable, and regularly priced at $139.

Cozy Earth provides free shipping for thes pillow. There’s also a 100-night trial, and a 10-year warranty. In comparison, Purple Harmony provides a 100-night trial period and a 1-year warranty, and Casper provides a 30-day trial period and a 1-year warranty.

Cozy Earth Silk Pillow review: design and materials

  • 100% mulberry silk fill
  • Bounces back but needs to be fluffed
  • Breathable bamboo viscose shell

The Cozy Earth Silk Pillow is filled with 100% mulberry silk that’s made exclusively for the company. It provides a supremely comfortable feel that’s soft as a cloud, but also thick enough to be supportive. The long strand mulberry silk is actually softer than other types of silk, and this is what creates such a luxurious feel.

Some pillows start off feeling soft, but then they start clumping – meaning there are soft spots in places, and also spots where the filling is now missing. However the filling in the Cozy Earth pillow never clumps. In fact, Cozy Earth guarantees this won't happen.

I have a set of standard size pillows, but they're also available in king size. The cover is made of 100% premium viscose from bamboo, which is designed to stay cool.

The pair of Cozy Earth Pillows arrived safely in a cardboard box. Inside, each pillow was in a stylish fabric bag with zipper closure, along with vegan leather handles and trim. I’d give the company full marks for presentation. Upon unzipping each bag, the pillows were encased in plastic as a sanitary measure. Since the pillows were not compressed, they didn’t have to expand, and I was not subjected to any off-gassing.

Cozy Earth Silk Pillow review: care and allergies

On its website, Cozy Earth recommends spot cleaning or dry cleaning the silk pillows. However, according to the tag attached to the silk pillow, it can be machine washed in cold water using normal detergent. However, no fabric softener or bleach should be used. Also, the pillows should not be put in a spin cycle. They can be machine dried on normal, or hung to dry.

The website also recommends using a protective pillowcase – in fact, a pillowcase is required to validate the manufacturer’s extended warranty. Cozy Earth also states that if you’re using a pillowcase and washing that pillowcase on a regular basis, then regular or excessive washing of the pillow is unnecessary.

Cozy Earth also recommends fluffing the pillow on a regular basis to maintain the loft and shape. In addition, it can be aired in the sunlight occasionally to keep it fresh. The pillow is OEKO-TEX certified, which means that it’s free from harmful chemicals. 

Cozy Earth Silk Pillow review: comfort & support

  • Plush yet supportive
  • Best for side or back sleepers
  • Refluffing is recommended

For over two weeks, I slept on a pair of Cozy Earth Silk Pillows to see how comfortable and supportive they were. The pillows provided an extremely comfortable experience, while also being supportive.

The pillows had a cloud-like softness, and were light and fluffy. They’re stuffed with 100% mulberry silk, which has a luxurious feel. The light and airy pillows were also able to cradle my head and neck in cocoon-like comfort. However, they bounced back when my head moved to another position.

Since the pillows have a mid to high-loft, they were the perfect height for me. I’m a combination sleeper, and this height works well for side and back sleepers. However, for sleeping on your stomach, the pillows may serve to be too high. Granted, not all side, back, and stomach sleepers are alike, so keep that in mind.

Cozy Earth recommends fluffing the pillows on a regular basis. In lieu of doing this, I just tossed them in the dryer for a few minutes.

Cozy Earth Silk Pillow review: temperature regulation

Mulberry silk is designed to resist mildew and eliminate moisture better than cotton, and I found that the Cozy Earth Silk Pillows kept me warm at night while sleeping. In addition, the cover is made from a 100% premium viscose from bamboo fabric, which is also designed to provide a smooth and cool sensation.

Even underneath winter bedding, the pillows seemed to regulate my body temperature, so I never woke up hot.  I tested the pillows during the fall/winter season, in Birmingham, AL, which tends to have mild winters.

Should you buy the Cozy Earth Silk Pillow?

Buy it if...

  You’re looking for a luxury pillow: This 100% mulberry silk pillow isn’t cheap. It’s a top-of-the-line pillow that’s designed to provide the ultimate in luxury. Sleeping on the pillow feels like your head and neck are cocooned in comfort, but it’s also supportive enough to avoid any aches and pains.

 You don’t like down or down alternative: Down pillows can poke you and may cause your allergies to flare up. On the other hand, down alternative pillows may not provide the same level of comfort. The Cozy Earth Silk Pillow is an alternative to both.

  You want a breathable pillow: The fill and the cover combine to provide a pillow that doesn’t trap heat. It regulates your body’s temperature to keep you cool while you sleep.

Don’t buy it if...

You’re a stomach sleeper: The pillow is a better choice for side and back sleepers. If you tend to sleep on your stomach, you may find the loft too high to keep your head and spine aligned while you sleep. As a result, you may wake up with aches and pains. 

You like to adjust the fill: While the cover does unzip, technically, the pillow isn’t designed to add or remove fill. Doing so may render your pillow useless, and also void your warranty.

You like to wash your pillows and covers: Cozy Earth recommends spot cleaning or dry cleaning your pillow. If you’re the type who likes to wash pillows on a regular basis, again, you may end up voiding your warranty. And even if you do wash it, the company warns against using the spin cycle, so it will take forever for the pillow to dry.

How I tested the Cozy Earth Silk Pillow

I slept on a pair of Cozy Earth Silk Pillows for over two weeks, testing for performance, comfort, and support. These tests were conducted during the fall/winter season. Since I tend to sleep hot – but I love all of the stylish fall and winter bedding – I slept with the HVAC off to avoid getting overly hot in my mild climate.
