Size ranges vary by style. Textured covers list fit ranges around 35.4–39.4" (length) and about 17.3–21.7" (width/height). High-stretch covers use size bands (Small/Large/X‑Large) that cover lengths from about 20" to 45", widths roughly 13"–22", and thicknesses around 15"–20".
High-stretch knitted jacquard and microfiber blends are the common stretch options. Listings commonly call out "high stretch knitted jacquard fabric" and microfiber blends such as 95% polyester / 5% spandex for elasticity and a snug fit.
Some non-stretch listings give fixed measurements. Examples include a non-stretch height of 18" and non-stretch widths reported around 32"–43" or a specific width listed as 42".
Common materials include jacquard and woven polyester (often listed as 100% polyester) and high-stretch microfiber blends (for example, 95% polyester / 5% spandex).
Covers use elasticized bottom bands, elastic cords, or super-stretchable skirts that wrap around the base to hold the cover in place and reduce slipping, providing full 360° coverage.
They protect ottomans from spills, daily scuffs and scratches, dust, and general wear and tear. Many listings emphasize 360° coverage as a barrier against spills and surface damage.
Installation is typically quick and tool-free. Most covers use an elastic band design—align the cover corners with the ottoman corners and stretch the elasticized skirt around the base for a snug fit.
