Sizes vary widely: small accent pillows can be about 8" x 8" to 12" x 12", lumbar-style cushions around 14" x 20", travel/novelty pillows near 12" x 12" x 7", and kids' nap mats or sleeping surfaces up to about 46" x 20" (some listings also note smaller built-in pillow sizes).
The assortment includes both adult-use accent pillows and kid-focused items. Some listings are labeled “Adult Use Only” for decorative pillows, while nap mats, character plushes, and sleep mats are described for toddlers and young children and come in kid-friendly sizes and construction (built-in or removable child-sized pillows, blankets, etc.).
