Description
Super Heavy-Duty Center Support Bar System
The STL Beds Super Heavy-Duty Center Support Bars are engineered for customers who demand the absolute best in strength, stability, and mattress protection. This is our most robust system—designed to integrate directly into your existing bed frame with headboard, footboard, and wooden side rails.
🛏️Superior Construction & Performance
This system includes four 1½″ industrial-grade angle iron crossbars that span the width of your bed:
- One bar positioned near the headboard
- One near the footboard
- Two additional bars evenly spaced between them
Each of the four crossbars includes three solid steel legs, and each leg features a threaded, adjustable foot—giving you a total of 12 legs and 12 feet. These evenly distributed supports transfer the weight directly to the floor, easing the load on your existing wood frame components.
We’ve gone a step further by adding two longitudinal braces (head-to-toe tie rods) that lock the entire structure together. This feature is exclusive to STL Beds and provides extra rigidity and stability not found in competing designs. It also helps prevent legs from shifting out of position—an issue common in lesser systems.
💪 Built for Demanding Applications💪
This system isn’t for the average sleeper—it’s designed for:
- Heavier individuals or plus-size couples
- Softside waterbeds
- Memory foam, gel foam, and hybrid mattresses
- Natural latex rubber mattresses
- Traditional mattress + box spring sets
With proper installation, our system can support over 2,000 pounds without compromise.
