Wake refreshed day after day atop the cushioning ease and superior support of King Koil's Wellesley Plush Innerspring Mattress, featuring hand-assembled Tailormade Tufting™ that maintains a consistent surface. Combining water-repellant Joma® wool, antimicrobial fibers, plush foam, and highly responsive Tranquility Foam at the quilt, comfort padding layers and a pillow insert of moisture-wicking graphite Talalay latex maintains an optimal temperature and relieves pressure points alongside strategically positioned perimeter zoned micro coils. Independently encased to minimize motion disturbances, the ContourFlex coil system offers full-body support, while the Excellent Edge™ foam encasement ensures stability and prevents roll-off.
