Extra Heavy Duty Full to Queen Convertible Bed Frame
Upgrade your bedroom—without replacing your entire bed. 🛏️
With the STL Beds Extra Heavy Duty Bed Frame Converter, you can transform your full-size bed into a queen-size 👑 sleeping surface while keeping your existing headboard, footboard, and bedroom furniture. Say goodbye to cramped quarters and hello to queen-sized comfort.
Born from collaboration with top-tier bed frame manufacturers, this frame combines the strongest features of multiple designs—just like assembling the perfect puzzle. The result? A best-in-class conversion frame known for its strength, stability, and smart engineering.
2 Versatile Connection Options
Bolt-up or Hook-in Attachment: We include both options. Whether your bed requires a bolt-up or hook-in type attachment, this frame provides a secure connection to both headboards and footboards. It’s particularly suitable for daily use /adult couples and those looking for the ultimate in strength, durability and mattress set support.
🔗 Hook-In Details
Connects flawlessly with hook in slot-type headboards and footboards, ideal for various mattress types including memory & gel foam, and latex beds. The frame’s construction is tailored to evenly distribute weight, ensuring a balanced and supportive sleeping surface.
🔩 Bolt-On Details
Accommodates bolt-on connections for headboards and footboards made of wood, metal, or iron, providing versatile and reliable support. This frame includes the same high-quality features as the hook-in model, with adjustable height options for the feet.
Measurements And Fit Of The Full-Queen Bed Frame Converter Rail System
Rail Length: 83 inches in length.
Low Profile Height Range: 5 ¾ -9″ Tall
High Profile Height Range: 5 ¾ -13 ½” Tall
Once the side rails are installed, whether you use the hook in or bolt on mounting plates, the system provides about an extra inch at each end of an 80-inch long queen-size mattress. This is the perfect distance: Still easy to make and pillows won’t slide between the mattress and headboard.
✅ Why the STL Beds Convertible Frame Stands Out
- More Sleeping Space: Expands your mattress from 54″ x 75″ (full) to 60″ x 80″ (queen).
- Effortless Upgrade: Keep your existing bedroom set—no need to buy all new furniture.
- Triple Crossbar Design: Includes head, middle, and foot support bars for unmatched stability and weight distribution.
- 6 Adjustable Feet: Fits a wider variety of bed heights with more enhanced stability.
- No Sagging, No Shifting: Prevents box spring and mattress droop and prolongs the life of your sleep system.
- Warranty-Friendly: Meets or exceeds all support requirements from major mattress manufacturers.
How It Works
- Advanced Retention System: Retainer L-brackets adjust to fit a queen foundation or box spring securely.
- Custom Center Support: Features adjustable cross arms and glides that adapt to your full-size headboard and footboard setup.
- Heavy-Duty Materials: Made from high-carbon USA railroad steel—side rails (2″ x 1.5″ x 12 GA), crossbars (1.5″ x 1.5″ x .100″).
- Queen Compatible Dimensions: Accommodates a 60″ x 80″ mattress; side rails are 83″ long.
- Triple Support Advantage: 3 center bars with individually threaded adjustable feet for superior load distribution and frame stability.
