The conclusion of any great concert, opera or performance is the finale. And so should it be with any great night's sleep. The Brentwood Finale features a 13.5 gauge tempered steel coil system that provides long-lasting and quiet support. The eurotop of the mattress include a thick layer of CertiPur-US certified foam for cushion and comfort. Every Brentwood Home mattress features a layer of all-natural wool at the sleep surface to provide you with a clean and healthy layer that naturally wicks away moisture and regulates your body temperature so you stay cool in the summer and warm in the winter.
