This replacement cushion pairs a soft shredded-foam top with a high-density foam core to provide pressure-relieving comfort while resisting collapse. It ships compressed for easy handling and regains its full form within 48–72 hours after unpacking.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cushion improve sinking and stiffness while keeping comfort?\u003c\/h3\u003e\n\n\u003cp\u003eThe two-layer construction separates surface comfort from structural support: a plush shredded-foam layer cushions the body, while a firm dense base prevents bottoming out.
