Walmart offers the Mainstays Ultra Collapsible Faux Leather Storage Ottoman in Black or Brown for $9.99. Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with our mention from three weeks ago, $20 off list, and the lowest price we could find. It measures 15" x 15" x 15" and holds up to 220 lbs.
Frugal isn't smart if you put off replacing these things. Waiting too long can cost money or even endanger your health.
