About the XL Twin Otis Zone 3
Enjoy the softness of this extra long mattress. This Zone 3 mattress is one of the softest, made with pressurized high-density foam. Four layers fill in between the Belgian damask shell. The foam filling conforms to your body shape as you lie down. The fabric's tailored edges will last for years. The exclusive Otis Comfort Lock Cushioning System tensions the material inside to create a consistent comfort level over the life of the mattress.
