Serta iComfort Twin XL or King (purchase 2) II Box Spring

Serta’s StabL-Base® Foundation is specifically designed to enhance the performance and appearance of every iComfort® Sleep System.  It provides consistent support across the bottom of the mattress and helps to isolate the impact of your sleep partner’s movements.  While many other memory foam systems use ordinary wood foundations that can break down over time, Serta’s StabL-Base foundation is made with extremely durable tempered steel and premium furniture-grade lumber.  Plus, the StabL-Base Foundation is finished with a beautiful cover that matches seamlessly with the mattress for a modern and tailored look.
