Crib 5 (BS 5852) Fire Test: What Actually Happens

If you’re specifying contract upholstery for a hotel, restaurant, office, bar, cinema, care setting etc., “Crib 5” is the phrase that keeps coming up.

For clarification:

Crib 5 = BS 5852 “Ignition Source 5”  is a UK contract upholstery fire test that uses a small flaming wooden crib to check how an upholstered seating build-up behaves under a realistic ignition challenge.

What happens in the Crib 5 test?

A lab builds a seat and places a small wooden crib on it. The crib is ignited using a syringe of alcohol so it burns like a real life open flame.

What the lab is watching for (in plain terms):

• Does it ignite easily?

• Does it keep flaming / grow?

• Does it self-extinguish within the required window?

  
  

All flaming should cease within 10 minutes for Ignition Source 5 testing.

Do you usually need FR treatment to meet Crib 5?

In practice: yes, many upholstery fabrics won’t achieve Crib 5 untreated.

Most projects get there via a treatment route typically involving:

• FR backcoating

• FR impregnation (where suitable),

• FR Lamination

We’re careful with Crib 5 work because performance shouldn’t come at the expense of the fabric. Rather than automatically applying a thick coating, we select the most appropriate route based on fibre blend, weave/pile structure and the finished handle you need - aiming for compliance with the minimum impact on appearance and feel.

Human-Centered Design Takes Center Stage at Atlanta Design Festival

September 27, 2025

Today, the Creative Futures Conference at the Atlanta Design Festival brought together thought leaders from across the creative spectrum to explore how design can drive radical transformation in business, culture, and community. With a lineup featuring visionaries like Nu Goteh, recipient of the 2025 Cooper Hewitt National Design Award, the conference delved into topics ranging from design for disability to the future of public spaces like Stone Mountain.

Embracing Human-Centered Design

A central theme of the conference was the shift towards human-centered design prioritizing the needs, experiences, and well-being of individuals in the design process. This approach emphasizes empathy, inclusivity, and accessibility, ensuring that design solutions are not only functional but also meaningful and impactful for diverse communities.

Textile Design: Beyond Aesthetics

In the realm of textile design, this human-centered approach is gaining momentum. Designers are increasingly considering how fabrics feel, how they contribute to comfort and well-being, and how they interact with other materials in a space. This holistic view is leading to more thoughtful and intentional choices in material selection, moving beyond mere aesthetics to encompass sensory experiences and emotional resonance.

Creating Material Families

One innovative concept discussed was the idea of "material families." This involves curating a cohesive selection of materials hard and soft

that work harmoniously together in terms of texture, color, and performance. By treating materials as interconnected members of a family, designers can create more unified and immersive environments that resonate on a deeper level with users.

Practical Takeaways for Designers

For designers looking to integrate these insights into their practice, here are some actionable tips:

• Prioritize Sensory Experience: When selecting materials, consider how they feel to the touch, how they sound, and how they contribute to the overall ambiance of a space.

• Consider Material Interactions: Think about how different materials will work together in a space, ensuring they complement each other in both aesthetics and function.

• Engage with Users: Involve end-users in the design process to gain insights into their needs and preferences, ensuring the final design truly serves them.

• Stay Informed: Attend conferences, workshops, and events to stay abreast of the latest trends and innovations in design.

10 Contemporary French Door Drapery Styles Designers Swear By

1. Ripple Folds for Seamless Flow

Opt for ripple-fold drapery that glides effortlessly along a concealed track. The uniform waves add a sleek, minimal silhouette, ideal for keeping sightlines clean while still allowing the doors to shine.

2. Inverted Pleats for Tailored Elegance

For a more structured look, in

verted pleats give each panel a crisp, architectural edge. This style works beautifully with heavier fabrics—think silk blends or velvet—and makes a strong visual statement when doors are left partially open.

3. High-Mounted Hardware to Lift the Space

Position rods or tracks just below the ceiling to create the illusion of soaring height. This simple tweak instantly amplifies room proportions, floods the space with light, and draws the eye upward to celebrate the full drama of your French doors.

4. Layered Sheers for Soft Diffusion

Combine blackout-lined drapes with a lightweight sheer behind them. By day, the sheers filter sunlight softly; by night, the blackout panels provide privacy and insulation. It’s the perfect balance of light control and energy efficiency.

5. Bold Color-Blocking for Contrast

Make your drapes pop by pairing a rich, saturated hue against neutral walls or vice versa. This high-contrast approach frames the doors like artwork and allows you to weave bold accent colors into your overall palette.

6. Textured Fabrics for Tactile Interest

Incorporate materials with tactile appeal think nubby linens, woven silks, or boucle to add depth and character. Textured weaves bring warmth to sleek glass panels and pair beautifully with living greenery or sculptural hardware.

7. Motorized Tracks for Effortless Operation

For the ultimate in convenience and luxury, motorized drapery tracks let you open or close treatments at the touch of a button (or via your smart-home system). They keep lines clean no cords in sight and elevate the experience for your clients.

8. Pattern Play with Subtle Prints

Select a subdued stripe or botanical motif to add pattern without overwhelming the doors’ classic geometry. Small-scale prints work best here, offering personality while maintaining an elegant, refined look.

9. Minimal Roller Shades for a Streamlined Vibe

If you prefer ultra-clean lines, motorized or manual roller shades in a sheer or light-filtering fabric can be tucked neatly above the door frame. They disappear when retracted, letting the doors take centre stage.

10. Custom Cornices or Pelmets for Architectural Cohesion

Pair drapes with a bespoke cornice board or upholstered pelmet that echoes window trim or ceiling mouldings. This custom approach ties the treatment directly into the room’s architecture, creating a polished, bespoke feel.

Why It Matters for TEK & Design Pros

At TEK, our flame retardant finishes preserve the drape, texture, and hand-feel of luxury fabrics whether you’re specifying linen, silk, or velvet.

Magnet Awarded the Manufacturing Guild Mark

Darlington, UK — Kitchen specialist Magnet has just been honoured with the Manufacturing Guild Mark, bestowed by The Furniture Makers’ Company to recognise outstanding standards in British manufacturing.
