Superior in design and comfort, the two-sided Lassen pillow-top mattress features the coveted BolsaTM coil system. Hundreds of individually wrapped coils respond independently to the unique contours of your body while simultaneously isolating the movements of one partner to another. Featuring edge to edge coil support, you’ll find stronger mattress edges for more support and more room to stretch. We finish it off with our traditional pillow-top with an added layer of soft upholstery for ultra-luxurious cushioning.
