Tree-Tapped Latex Pillow Fill Refill

Slow-pour Dunlop latex starts as sap from Hevea brasiliensis rubber trees on FSC certified plantations in Sri Lanka, tapped the way maple syrup gets tapped. The sap is poured into a mold and cured slowly in small batches, longer than the continuous-pour method used in mass production. That longer cure time locks in a uniform open-cell structure top to bottom, with air pockets connected from one side to the other.

This refill is the same shredded slow-pour Dunlop latex used in every Circadian Tree-Tapped Latex Pillow, sold by weight so you can adjust loft to your preferred firmness. Open your pillow's side zipper, pull pieces out for a lower profile or add them back for more height, seal it back up. Slow-pour Dunlop holds its loft for years, but when your sleep position shifts or you want to dial in a different feel, this refill gives you the same fiber to do it with.

The two credentials, briefly

The finished latex is certified to OEKO-TEX Standard 100 at Class 1, the strictest tier in the program, tested to the same safety threshold used for products designed for direct contact with infants and babies. The cover that wraps the pillow stays in place. Only the fill comes out and goes back in.

The upstream rubber-tree source is FSC certified (Forest Stewardship Council), which means the latex sap comes from independently audited responsible-forestry plantations rather than clear-cut or unmanaged land. Most natural latex pillows can claim OEKO-TEX Standard 100 on the finished material but cannot claim FSC on the upstream source.

What you get

3 pounds of shredded slow-pour Dunlop latex pieces in a sealed bag. Enough to fully refresh a Standard, Queen, or King Tree-Tapped Latex Pillow.

How to use it

Open the side zipper on your Circadian Tree-Tapped Latex Pillow and add or remove latex pieces a handful at a time. Test the loft after every handful or two, since small amounts make a noticeable difference. Latex pieces settle into place within a night or two and rebound the same way the original fill does. Store unused pieces in the sealed bag away from heat and light so they hold up for the next refresh.

A note on scent

Fresh slow-pour Dunlop latex has a mild rubber scent that fades within 3 to 7 days. The smell is harmless and comes from the latex itself. If you're scent-sensitive, air the bag's contents in indirect sunlight for an afternoon before adding to your pillow.

Latex allergy

If you have a latex allergy, this refill is not for you. Even with the cotton barrier of the pillow cover, latex allergens can transfer in a small but real fraction of cases. The Wild-Harvested Kapok, Organic Cotton, and Organic Wool refills are all latex-free.
