Alternating Coil Design
Standard innerspring designs have a tendency to lean under pressure, causing unwanted
motion transfer. Our unique, alternating coil design reduces motion transfer while
still offering restorative support for a sound sleep.
Extra Comfort Layers
Dover mattresses feature extra comfort layers made with latex, visco elastic or
convoluted polyurethane to provide additional pressure relief and further reduce
the effects of “tossing and turning.”
TheraFoam® encasement Improves stability while increasing the usable sleep surface
by eliminating "roll together" and border breakdown.
Last, but certainly not least, every King Koil product is backed by the best warranty
available. You’ll get a better night’s sleep knowing that you’ve purchased one of
the world’s finest mattresses, which is supported by a worldwide warranty.
Our exclusive HourGlass polypropylene insert increases support and firmness by 18%
at the shoulders & hips and 13% at the lumbar area. This flexible technology can
be combined with virtually any coil unit to offer improved performance and added
value at any price point.
- Exclusive, enhanced support grid increases firmness in critical areas.
- Open spring design provides progressive resistance as weight is applied, improving
support where body weight is centered.
- Zoned coil configuration allows for the density of coils to vary across the sleep
surface in order to offer tailored support to every part of your body.
Maintain proper spinal alignment
Research has shown that anatomically correct support for your spine helps keep your
back healthy and can have therapeutic benefits.
To maintain proper spinal alignment, our HourGlass Back Support® System provides
zones of support for the different regions of your spine. This allows you to rest
in a completely neutral position for optimum rest and recovery.
Unique Coil Design
These zones of support are further enhanced by our patented reactive coil design.
As weight bears down on individual coils, they respond with increasing support.
The result? By conforming to the shape of the body and providing balanced support
from head-to-toe, our Dover mattress gives you the uninterrupted sleep you need.
