Tri-fold construction is the difference here: this 72 inch lounge pad folds into thirds for storage, and at 3 lbs it carries to the beach or into a shed with one hand. It runs 1.8 inches thick rather than deeply stuffed, layered with multi-layer foam under a breathable short fiber fabric that stays soft against skin. Hook and loop fastener straps wrap the chair frame to stop the pad sliding, and they sit flush so they do not break up the surface. Sections run 45.5 inches for the seat and 26.5 inches for the back, matching a standard chaise. Overall it measures 72 by 23 inches and the fabric holds its resilience through sunny days by the pool. Folding it in three also lets you set the support where you want it rather than only under the seat.
