What’s In A Squishmallow?
Squishmallows are crafted from ultra soft spandex exterior fabric filled with specialized polyester fibers. This premium material combination creates their distinctive, marshmallow-like texture, which is perfect for cuddling, collecting, and therapeutic comfort.

Materials Used In Making Squishmallows
Polyester Fibers Filling
Polyester fibers serve as the primary stuffing material in every Squishmallow. This synthetic filling offers several key advantages:
-
Stain and mildew resistance — maintains freshness over time
-
Shape retention — bounces back after compression
-
Quick-drying properties — easy to clean and maintain
-
Hypoallergenic nature — safe for sensitive skin
Unlike traditional stuffing that can clump or flatten, Squishmallows use a proprietary cluster fiberfill designed to rebound to its original form. This specialized blend provides the perfect balance of softness and structural integrity, making these stuffed toys so distinctive.
Ultra Soft Spandex Exterior
The outer shell features ultra-soft spandex (approximately 85% polyurethane), chosen for its exceptional properties:
-
Superior elasticity — stretches without tearing or losing shape
-
Smooth texture — creates the signature "marshmallow feel"
-
Vibrant color retention — maintains appearance through repeated washing
-
Lightweight durability — withstands regular use and cuddling
This spandex is laminated to a polyester base, enhancing durability and preventing pilling. The combination ensures your Squishmallow stays super soft and colorful for years. But how do you ship Squishmallows?
Are Squishmallows Safe? Understanding Safety Certifications
Squishmallows do not have toxic chemicals. They meet the toy regulatory and safety standards, so they are safe for kids of all ages and the young at heart. Squishmallows comply with Prop 65, and manufacturers certify that they don't incorporate harmful chemicals into the product — in its internal and external layers — a key reason these plush toys have maintained their popularity among consumers and collectors.
One important clarification: Despite what you may have read elsewhere, Squishmallows are not flame retardant. The official Squishmallows support page explicitly states they are Prop 65 compliant and are NOT flame retardant. This misconception is widely repeated in third-party articles — the manufacturer's own statement is definitive. Always check the official tag when assessing whether a stuffed toy is flame retardant.
Squishmallows meet the following safety standards:
-
Prop 65 compliant — free from harmful chemicals and toxins
-
ASTM F963 certified — meets the mandatory U.S. Consumer Product Safety Improvement Act toy safety standard. Note: The current mandatory standard is ASTM F963-23, which replaced F963-17 effective April 20, 2024. [2]
-
Third-party tested — verified free of lead and phthalates
-
Hypoallergenic materials — suitable for kids and adults with sensitivities
-
Reinforced seams — prevent fiber leakage and choking hazards
-
Embroidered facial features — eliminate the risk of small parts
-
Age-appropriate sizing — from 3.5 inches to 24 inches across 12 size options
Are Squishmallows Safe for Toddlers?
Many Squishmallows carry a "3+" label based on potential choking hazards — not material toxicity. For children under 3, look for:
-
Embroidered eyes and nose — not plastic button eyes, which can detach
-
Larger sizes — 12 inches and up reduces aspiration risk
-
Tight, even stitching — seam integrity matters for active play
-
No removable accessories — bows, hats, or attachments that can detach
How Are Squishmallows Manufactured?
Squishmallows are manufactured in China by Kelly Toys Holdings LLC — also known as Kellytoy — the parent company behind the brand. Squishmallows manufactured in China go through strict quality controls.
As of 2024, over 400 million Squishmallows have been sold across retail stores and online channels — making Squishmallows among the best-selling plush toys in the world — a brand that has sold hundreds of millions of units and sold its way into homes across every continent, with distribution spanning retail stores and online channels worldwide. Kelly Toys Holdings LLC oversees the entire manufacturing process, which includes:
-
Polyester granule extrusion into continuous filaments using a batch process or continuous polymerization
-
Spandex knitting and dyeing, creating vibrant exterior fabrics that give each character its created look
-
Precision cutting, sewing, and quality inspection at each stage of the process — every Squishmallow is created with consistent standards, and the designs are created to reflect each character's unique personality
The production of Squishmallows in China allows Kelly Toys to maintain consistent quality across characters and keep up with global demand.
Each authentic Squishmallow features three identification tags: a bio tag with character information (each of the hundreds of characters has a unique bio), a woven Kelly Toys label, and a sewn-in compliance tag. Post-2021 models also include a scannable QR code on the sewn-in tag for authenticity verification.
Are All Squishmallows Made Using The Same Materials?
All Squishmallows are made with identical core materials — polyester fiber stuffing and ultra-soft spandex exterior. This consistency ensures:
-
Uniform texture across all characters and sizes
-
Predictable quality for collectors and gift-givers
-
Reliable comfort for therapeutic and sensory use
While the shell texture may feel slightly different between sub-lines by design (FuzzAMallows have a fuzzier surface finish, for example), the base material composition remains the same throughout the entire lineup.
Unlike other brands that vary stuffing materials across product lines, Squishmallows are made with the same polyester fibers in every style — and the materials Squishmallows are made of, as well as the process for making Squishmallows, remain consistent worldwide — a consistency that collectors and fans around the world have come to rely on.
But what was the first Squishmallow?
How to Identify Authentic Squishmallows
Authentic Squishmallows feature three official tags, meet safety certifications, and have the characteristic ultra-soft spandex feel.
The combination of specialized polyester cluster fiberfill and a soft spandex shell creates their distinctive marshmallow-like texture — a signature that other plush animals and stuffed toys simply haven't been able to match — something counterfeit plush toys consistently fail to replicate.
When authenticating a Squishmallow, check for:
-
Three tags — hang tag with bio, woven Kelly Toys label, and sewn-in compliance tag
-
The right feel — consistent, springy softness that bounces back immediately; fakes feel rough, thin, or flat
-
Embroidered facial features — not plastic safety eyes
-
Standard sizing — authentic sizes run 3.5, 5, 7, 8, 11, 12, 13, 14, 16, 20, and 24 inches
Counterfeit Squishmallows may skip mandatory safety testing entirely, meaning materials may not meet current ASTM F963-23 standards. Purchasing from authorized retailers ensures every certification is real.
Consumers who purchase from trusted sources also protect themselves from stuffed toy products made with unverified chemicals or substandard fillings. Every authentic stuffed toy from Kelly Toys Holdings meets certified safety standards.

Proper Care Instructions for Your Stuffed Toy
Follow these steps to maintain your Squishmallow's quality:
-
Spot cleaning: Use a damp cloth for small stains
-
Gentle machine washing: Place in mesh bag, cold water, mild detergent
-
Air drying: Allow complete air drying to prevent shrinking
-
Fluffing: Gently massage to redistribute filling evenly
-
Storage: Keep in clean, dry areas away from direct sunlight
Important: Avoid high-heat drying, as it can damage the spandex fibers and polyester filling used in making Squishmallows.
Can You Make A Homemade Squishmallow?
Creating homemade versions is possible using similar materials:
Required materials:
-
Ultra-soft spandex or minky fabric
-
Cluster polyester fiberfill
-
Embroidery thread for facial features
-
Sewing machine or needle
Pro tip: While DIY versions can be fun projects, they typically won't match the precise density and texture of authentic Squishmallows due to proprietary manufacturing techniques. Making Squishmallows at scale involves specialized equipment and other materials that the production process at Kelly Toys Holdings LLC requires — and that home crafters simply can't replicate. For the genuine squish, Toynk Toys carries the real thing in our Squishmallow collection.
A Note on Squishmallows and Sustainability
Since Squishmallows are made from polyester fibers and spandex — both petroleum-derived synthetic materials — they carry the same environmental considerations as other synthetic plush toys. The polyester fibers used are non-biodegradable and shed microplastics, like other synthetic fibers.
The Kellytoy tag reads "All new material," confirming no recycled content is used in production. Polyester is non-biodegradable, and spandex is difficult to recycle. Squishmallows' safety certifications (Prop 65, ASTM F963) address toxicity, not environmental impact.
For eco-conscious fans who collect Squishmallows, donating or gifting them rather than discarding them is the most practical way to extend their life cycle.
FAQs
Are Squishmallows toxic?
No. Squishmallows do not contain toxic chemicals. They are Prop 65-compliant and ASTM F963-certified. Manufacturers confirm that no toxic chemicals or harmful substances are incorporated into the internal or external layers. Independent testing further verifies that toxic chemicals like lead and phthalates are absent.
Are Squishmallows flame-retardant?
No — and this is a common misconception. The official Squishmallows support page explicitly states: Squishmallows are Prop 65 compliant and are NOT flame retardant. Many plush toys from other brands are also not flame-retardant by default. Prop 65 compliance covers toxicity, not fire resistance.
Are Squishmallows safe for babies and toddlers?
Squishmallows meet U.S. toy safety standards, maintaining their Prop 65 compliance and ASTM certification across all product lines, and many carry a "3+" label based on potential choking hazards rather than material concerns. For children under 3, choose larger sizes (12 inches and up), look for embroidered rather than plastic eyes, and avoid styles with detachable accessories.
How do you wash Squishmallows?
Current official tag guidance is hand-wash and air-dry only. Hand wash with mild detergent in cool water, gently squeeze out excess water without compressing the filling, then lay flat to air dry completely. Avoid heat sources, fabric softener, and top-loading washing machines with agitators.
Do all Squishmallows use the same materials?
Yes. All authentic Squishmallows — including sub-lines like HugMees, FuzzAMallows, and Squish-Doos — use the same core polyester fiberfill and spandex-polyester shell. Every Squishmallows made in any style shares the same material DNA, so the Squishmallows made as limited editions feel identical to everyday styles. Shell texture may vary slightly between sub-lines by design, but the base material composition is consistent across the entire lineup.
How do I verify the authenticity of Squishmallow materials?
Authentic Squishmallows feature three official tags, meet safety certifications, and have the characteristic ultra-soft spandex feel. Learn more about how to register Squishmallows.
