Standard patio furniture often feels punishingly hard against your back, but the Arden Selections ProFoam Essentials cushion changes that dynamic with its substantial 3.5-inch thickness.

The Sapphire Blue Leala print looks vibrant, and the DWR treatment actually does its job by repelling water and resisting UV fading.
