Materials
FluffBase Cooling Eucalyptus Down Alternative Pillow
Cooling & Moisture Wicking TENCEL™ Lyocell fiber pillow
The fancy name for eucalyptus fibers—is one of the most sustainable fabrics in the game, made from the pulp of FSC & PEFC-certified eucalyptus wood. By nature, this material is cool, soft, and moisture-wicking, making it ideal for comfy sleep.
Composition: 100% TENCEL™ lyocell removable cover, and recycled polyester down-alternative core.
TENCEL™ lyocell sourced in Central Europe, final product constructed in Shanghai, China.
Care
We recommend washing the pillow cover and core separately. Machine wash cold on a gentle cycle. Tumble dry low. Remove promptly. For the best results long term, please avoid using fabric softeners, bleach, or washing with anything rough that could cause excess pilling, like wool dryer balls, items with zippers or Velcro or rough fabrics. Don’t forget that some pilling is normal for natural fibers! Following these tips will help reduce the risk of excess pilling.

Third-party tested
Someone else checked our work.
Tested, not just claimed. · Optional. We did it anyway.
None of it is required. We do it because “trust us” isn’t good enough for something you sleep against every night.
OEKO-TEX® STANDARD 100
Every component tested for harmful substances — the fabric, the fill, the thread and the dyes.
FSC® MIX
The wood pulp behind the Lyocell is traced to responsibly managed forests, not just “sustainably sourced”.
Asthma & Allergy Friendly®
Independently tested to hold less of what sets off asthma and allergies.
Global Recycled Standard
Certifies the recycled content in the fill is really recycled — tracked from reclaimed material to finished product.

Cover
Cooling TENCEL™ Lyocell
Quilted shellA 100% TENCEL™ Lyocell shell quilted with TENCEL™ fiber inside. It is naturally cooling — the fiber breathes and wicks moisture away as you sleep.
Composition — 100% TENCEL™ Lyocell removable cover. Care — machine wash cold on a gentle cycle with like colors, tumble dry low, remove promptly.
02 Inside
Fill
Down-alternative microfiber fill
Two support optionsPlush, down-like fill with the softness of down and none of the allergens. It comes in Soft or Firm, and the option you pick is what sets the loft — the fill itself is not something you change later.
Composition — recycled polyester down-alternative core. Care — wash the cover and the core separately. No fabric softener or bleach, and nothing rough in the load.
03 Support
Two options: Soft, or Firm.
Soft
Firm
Lower, flatterHigher, loftier
Soft suits back and stomach sleepers; Firm suits back and side. Back sleepers appear under both, so if you sleep low and flat take Soft, and if you like a high, lofty pillow take Firm.

Cover
Cool-touch knit
Cool to the touchThe knit feels refreshing the moment you lie down and lets heat escape rather than build up. The cover comes off and goes in the machine.
Composition — ultra-cooling nylon, removable. Care — machine wash cold on a gentle cycle with like colors, tumble dry low.

Fill
Talalay latex core
Never falls flatOne piece of airy, perforated Talalay latex, not shredded fill. It conforms to your head and neck, then springs back — pressure relief that returns to shape instead of needing to be fluffed. Spot clean only.
Composition — Talalay latex foam core. Care — spot clean as needed with a mild detergent, then air dry.
03 Support
One feel: Medium Soft.
Lower, flatterHigher, loftier
Nothing to choose and nothing to adjust. The 6-inch latex core fixes the loft, which is what makes it work for side sleepers who need shoulder room and back sleepers who do not want to be pushed forward.

Fill
Shredded memory foam plus microfiber
You set the loftMemory foam brings the support and microfiber brings the softness, and the amount in the pillow is yours to decide. It ships with a fill pouch: add for a higher loft, take some out for a lower one. This is the only pillow here where loft is a customer variable rather than a fixed property.
Composition — 90% shredded memory foam, 10% polyester fiber blend. Care — spot clean as needed with a mild detergent, then air dry.
03 Support
One feel, and you are the one who sets it.
Lower, flatterHigher, loftier
Every other pillow decides the loft for you. This one arrives with a fill pouch so you can move anywhere along the range until it is right — which is why it is the answer when no pillow has ever felt correct, or when you change position through the night.

- MDMelanie D.Verified BuyerReviewingCloudSupport PillowI recommend this productRated 5 out of 5 stars9 months agoMy Dream Pillow
I have always had an issue when I needed to purchase a pillow. Originally I found down pillows and they were great for many years. Then they weren't. All of them pancaked and became utterly worthless. Then I started trying contour pillows, shredded memory foam, solid memory foam, other shredded varieties, etc.. Some worked for me briefly and others just gave me beck aches. Then I found this Sijo CloudSupport Pillow. It is unlike any pillow that I have ever owned. The cover is so soft I almost hate to put it in a pillowcase on it but I want to protect it. It is always cool to the touch, something I never thought possible. This pillow has worked perfectly for me from day 1. I can sleep on my side, stomach or back and be perfectly comfortable. I ordered a second one as to have a back up in case anything happens to it. I can not recommend this pillow enough! BTW, this is the longest review that I have ever written because I am so happy with it.
- TBTeresa B.Verified BuyerReviewingFluffBase Eucalyptus PillowI recommend this productRated 5 out of 5 stars11 months agoMy Dream Pillow
I've had many pillows over the years, some I have to return or donate because of a sore neck or general discomfort, some have been pretty good! This Eucalyptus Pillow outdoes them all. I bought in Soft, and the lightness and malleability is truly like a down pillow. You can scrunch it, punch it, tuck it under your neck, and it never loses shape or packs down. A low "loft" which makes it very comfortable for the neck and shoulders. Truly, the best pillow I've ever owned.
- MTManatsu T.Verified BuyerReviewingCloudSupport PillowI recommend this productRated 5 out of 5 stars1 year agoLiterally gives you cloud support
I was super surprised when I first laid my head on this pillow—- it is soft as a cloud but it for sure has the support!!! I understood why it was names cloud support in an instant. My neck pain is relived and it supports you so well whether you are a back sleeper or a side sleeper! Super impressed, highly recommend
