The Spencer double Open Coil Mattress features a traditional firm open coil spring system. This is made up of rows of hourglass shaped springs that are linked into one single unit using a spiral wire at the top and bottom.
A thick rod-edge wire is then fitted around the top and bottom of the spring unit. This provides edge to edge comfort across the full width of the sleeping surface; prevents border breakdown and ensures the mattress retains its shape. 10" thick mattress.
