How much weight can a storage ottoman bench actually hold?

Folding fabric/faux-leather ottomans like the SONGMICS and DUMOS models commonly list a 660 lb capacity, while upholstered wood-frame benches such as the WUTUTUEE 51" list 500 lb. Verified-purchase reviewers across Amazon and Walmart generally confirm the benches handle adult seating without sagging, though folding models rely on MDF panels rather than solid wood and shouldn't be used as primary seating long-term.
