25 Essential Parts of a Bed Frame

🛏️ What Is a Bed Frame?

A bed frame is the foundation that supports your mattress and, in many cases, your box spring. It raises your bed off the floor, provides structural support, and often adds aesthetic value to your bedroom.


🧱 Main Structural Parts of a Bed Frame

1. Headboard

The headboard is the upright panel located at the head of the bed. It offers back support while sitting up and serves as a decorative element.

2. Footboard

Located at the foot of the bed, the footboard balances the design and can help keep bedding in place.

3. Side Rails (Bed Rails)

These long horizontal bars run along both sides of the bed, connecting the headboard to the footboard. They support the base of the bed.

4. Center Support Rail

A strong beam running from the head to the foot of the bed in the middle. It provides extra stability—especially for queen- and king-size frames.

5. Slats

These are horizontal planks that sit across the frame to support the mattress. They can be wooden or metal and are either spaced apart or fully solid.


🦾 Support and Reinforcement Components

6. Support Legs (Middle Legs)

Extra legs that attach to the center support rail to prevent sagging and distribute weight evenly.

7. Corner Legs

The four main legs—one at each corner—that support the overall weight of the bed and its occupants.

8. Glides

Flat-bottomed feet or caps on the bottom of bed legs that prevent floor scratches and help with sliding the bed.

9. Caster Wheels

Some bed frames come with small casters for easy movement. These may have locks to prevent rolling.

10. Support Beams

Heavy-duty crossbars that connect the two side rails and provide additional reinforcement under the slats.


🪛 Connection and Fastening Components

11. Bolt-On Brackets

Used to connect the headboard and footboard to the side rails using bolts.

12. Hook-On Brackets

An alternative to bolts; these allow you to slide the frame parts together using metal hooks.

13. Bed Frame Screws and Bolts

Various nuts, bolts, and screws are required to fasten all parts securely.

14. Support Brackets

Metal or wood reinforcements placed at stress points, especially where slats meet rails.

15. L-Brackets

L-shaped metal pieces often used to secure corners and joints.


🧰 Additional Frame Parts and Features

16. Mattress Platform

In platform beds, this solid surface replaces the need for a box spring and supports the mattress directly.

17. Box Spring/Foundation

Not part of the bed frame itself, but rests inside it. Provides extra lift and support for the mattress.

18. Bunkie Board

A slim board that adds support under the mattress, usually on platform or slatted frames.

19. Bed Risers

Optional add-ons placed under the legs to raise the bed’s height for added storage or comfort.

20. Underbed Storage Drawers

Slide-out compartments built into the lower part of the frame to store clothing, shoes, or linens.


🧩 Specialty Frame Parts

21. Trundle Frame

A lower, wheeled frame stored under the main bed that holds an extra mattress for guests or children.

22. Canopy Posts

Tall posts at each corner of the frame that support a canopy or fabric drape.

23. Side Panels (Decorative Trim)

Used to hide under-bed storage or complete the bed’s aesthetic design.

24. Headboard Slats (Decorative)

Vertical or horizontal wooden bars inside the headboard, often found in classic or rustic styles.

25. Connector Plates

Small metal plates that link separate frame sections, offering extra reinforcement and security.
