The Augusta2 from Ashley's Sierra Sleep line is a 12-inch Euro pillow top mattress with a firm comfort level and a thoughtfully layered build. At its foundation sits a wrapped coil system for even support across the sleep surface, surrounded by a high-density foam encasement that stabilizes the edges. Above the coils, the comfort layers stack in purposeful order: high-density base foam, gel memory lumbar support foam for cooler sleep in the lower-back zone, firm support foam, and a firm convoluted quilt foam that gives the top its characteristic feel. The result is a mattress that sleeps cool and supportive without any plush give.
The cover earns its own mention. It's a stretch fabric treated with a nano stain-resistant and waterproof finish, and it doubles as a bed bug, dust mite, and allergen barrier — a concealed micro-teeth zipper with a patented zip-tie closure keeps it secure. The mattress ships compressed and rolled in a box; give it at least 48 hours to fully expand before sleeping on it. It's also compatible with adjustable bases, and comes backed by a 10-year non-prorated warranty.
