1. In mattress manufacturing, what is the primary purpose of tufting?
A. To apply fire-retardant chemicals
B. To attach the ticking to the core
C. To secure internal layers and prevent shifting
D. To cut foam layers to size
Rationale: Tufting mechanically binds internal layers of a mattress to
stabilize the core materials and prevent shifting during use.
2. What does ILD stand for in foam specification?
A. Internal Load Density
B. Indentation Linear Degree
C. Indentation Load Deflection
D. Individual Layer Durability
Rationale: Indentation Load Deflection (ILD) measures foam firmness
by the amount of force required to indent the foam a specific depth.
3. Which material is most commonly used for mattress edge support?
A. Cotton batting
B. Memory foam
, C. High-density foam or steel coils
D. Polyester fiberfill
Rationale: High-density foam or reinforced steel coils are used to
strengthen perimeter support, preventing sagging at the mattress
edges.
4. What is the purpose of fire barrier materials in mattresses?
A. To improve comfort
B. To meet flammability safety regulations
C. To add aesthetic appeal
D. To reduce manufacturing cost
Rationale: Fire barrier materials are integrated to comply with safety
codes by slowing ignition and flame spread.
5. In innerspring mattresses, what does “coil gauge” indicate?
A. Height of the coils
B. Thickness of the coil wire
C. Number of coils per square foot
D. Type of pocketing
Rationale: Coil gauge refers to the thickness of the wire used for the
coils, with lower numbers indicating thicker wire.
6. Which of the following is a typical allowable tolerance for mattress
thickness in quality control?
A. ±0.25 mm
B. ±0.1 in
C. ±0.5 in
D. ±2 in
Rationale: A ±0.5 inch tolerance is a common industry standard to
ensure consistent product dimensions.
7. What is the main benefit of using pocketed coils?
A. Lower cost of materials
, B. Reduced motion transfer
C. Increased edge sag
D. Easier tufting
Rationale: Pocketed coils operate independently, which reduces
motion transfer between sleeping partners.
8. Which tool is primarily used to cut foam layers accurately?
A. Hand saw
B. Laser cutter
C. Electric foam saw
D. Rotary cutter
Rationale: Electric foam saws are designed to slice foam cleanly and
precisely to desired dimensions.
9. What does “ticking” refer to in mattress manufacturing?
A. The internal spring unit
B. The fabric covering the mattress
C. The foam core
D. The edge support system
Rationale: Ticking is the outer fabric material that encases the
mattress layers.
10. Which inspection should be performed before stitching the
mattress cover?
A. Visual check of box springs
B. Measurement and defect check of panels
C. Final packaging inspection
D. Flammability testing
Rationale: Panels must be measured and checked for defects before
stitching to ensure proper fit and quality.
11. What is the purpose of quilting?
A. Reducing mattress weight
