Product Details
STL Beds Exclusive Heavy-Duty Hook-On / Bolt-On Frame (Twin | Full)
This frame is engineered exclusively for STL Beds and built to outperform the flimsy, lightweight frames found in big-box stores.
- Heavy-duty offset brackets with multiple slots to fit more headboard and footboard widths
- Comes with both hook-in and bolt-on connection hardware — use whichever your bed requires
- 7 total legs for exceptional stability
- Side-to-side center support bar spans the width of the frame in the middle (Twin & Full design)
- Adjustable leveling feet help set the proper height for headboard and footboard attachment points
- Constructed with hardened steel 1.5″ x 2.0″ angle-iron side rails (stronger than 1.25″ or 1.5″ or square tubing used in competitor frames)
- Bolted assembly (nuts, bolts, lock washers) for maximum rigidity and long-term durability
- No wooden slats needed — this is a complete support system
- Wide feet help distribute weight over a larger surface area for improved stability and carpet protection
Heavy-Duty Performance
Because this frame is designed to handle the weight of a soft-sided waterbed, it easily supports:
- Heavy adults
- Heavier mattress types (latex, hybrids, deep memory foam)
- Long-term daily use
- Beds in high-wear environments
A Deep Fill Full soft-sided waterbed weighs about 825 lbs plus mattress, bedding, and an adult or adult couple. This frame is built with that type of load in mind.
Connection Options (Both Included)
This frame ships with both connection styles:
Hook-In Brackets (Included)
- Fits traditional hook-slot headboards and footboards
- Uses durable downward-facing claws
- Provides a solid, non-loosening connection
- Ideal for older wood beds, antique beds, and furniture-style bed ends
Bolt-On Brackets (Included)
- For wood, metal, or iron headboards & footboards that use bolts
- Strong steel plate design
- Adjustable leveling feet help you match up the exact height of your attachment points
Choose the option that matches your bed — everything you need is in the box.

- Built from hardened, high-carbon steel
- Reinforced 1.5″ × 2.0″ angle-iron side rails

- Includes three one-piece support bars: head, middle (side-to-side), and foot
- Each support bar includes its own legs for stability
- 7 total legs with leveling adjustment

Key Features
- 7-leg design provides superior support compared to typical 4–6 leg frames
- Side-to-side center support bar adds structural rigidity across the width of the bed
- Durable offset connection brackets fit more bed styles
- Hardened-steel 1.5″ × 2.0″ side rails (a major strength upgrade over common 1.25″ or 1.5″ rails)
- Both bolt-on and hook-in brackets are included.
- Built exclusively for STL Beds for long-term, heavy-duty use
Replaces Weak Or Missing Rails
This Twin/Full Bed Frame Headboard & Footboard can replace most Twin or Full metal rail systems, including:
- Broken angle rails
- Missing center support systems
- Weak or lightweight bolt-on frames
- Hook-in rail sets with no center support
The STL Beds exclusive design includes real center support, reinforced brackets, and 7 legs — features you won’t find on typical metal frames.
