Thickness varies by item type: thin sleeping mats are about 1 inch; plush travel/cloud pillows typically range from about 3.5 to 5 inches; and larger character plush pillows can be up to about 7.9 inches.
Certifications vary by listing: some products explicitly show OEKO‑TEX STANDARD 100, while at least one toddler pillow listing indicates "No Certifications." Check each product’s detail page for the specific labels for that item.
Most covers are polyester‑based: many list microfiber or 100% polyester covers, and some plush-style covers use a polyester blend (for example, 94% polyester and 6% spandex).
