The conclusion of any great concert, opera or performance is the finale. And so should it be with any great night's sleep. The Twin size 11-inch Thick Quilted Euro-top Innerspring Mattress is the flagship offering from our Brentwood Performance Series, and represents the confluence of cutting-edge mattress construction, sleep technology, and materials science. Six inches of Certipur-US Certified soft comfort foam is integrated into an extra-plush, extra-thick, eurotop that provides a rejuvenating and restful sleep. The queen size innerspring construction boasts 390 13.5 gauge tempered steel springs that work together to give durable and quiet support, while padded upholstery layers and a quilted surface provide the extra softness needed for the kind of sleeping experience one would expect from a top-of-the-line mattress. The Finale's innovative combination of innerspring construction, combined with Certipur-US Certified foam, assures every sleeper that they will not only have the best possible night's sleep, but also one free from the dangers of off gassing from volatile, organic compounds (VOCs). As with all our Brentwood brand models, the Finale works perfectly with our RestEasy Instant Fully Assembled Box Foundation, making foundation selection a breeze. Each mattress is made in the USA, comes with a 1-year warranty and is compressed and rolled for easy carrying, while saving you money on shipping costs.
