BENEFITS Guaranteed comfort when you sleep on the Sparrow; select your optimal feel and ensure it lasts with the LRE. Free exchange to another feel, you keep the mattress, and we send a new layer. Free returns in all states. King and Cal King can be ordered as internally split comfort layers, granting each side of the bed a different firmness level. Energex foam is responsive and offers a memory foam-like feel without leaving a lasting imprint on the mattress. Individually wrapped coils isolate motion (so you won’t wake up when your partner reaches for a glass of water in the middle of the night).
