LOCK STITCH VS CHAIN STITCH
WHICH QUILTING TECHNOLOGY FITS YOUR PRODUCTION BEST
At Bestfoam, we often get asked one simple but important question:
“Which type of quilting machine is better – Lock Stitch or Chain Stitch?”
Both technologies dominate the textile industry and together represent over 90% of all sewing processes in the garments industry. Yet, each has unique advantages depending on the type of product, material, and production goals.
In this article, we’ll explain the main differences between Lock Stitch and Chain Stitch quilting, and help you identify which system suits your manufacturing line best.
WHAT IS A LOCK STITCH?
A Lock Stitch is formed using two separate threads – one from the needle (top thread) and one from the bobbin (bottom thread).
These two threads interlock inside the fabric, creating a tight, durable stitch that resists unraveling even when cut or exposed to tension.
Main Advantages:
- High strength & durability – perfect for products under tension or frequent washing
- Clean appearance – identical top and bottom sides
- Minimal thread waste – efficient for mass production
- Suitable for thick or layered fabrics such as bedding, duvets, and mattress covers
- Stable and low maintenance with consistent stitch formation
Typical Applications:
Lock Stitch quilting is ideal for:
- Bedding and duvets
- Mattress top panels
- Jackets, outerwear, and home textile decor
- Products that require longevity and precision

WHAT IS A CHAIN STITCH?
A Chain Stitch, on the other hand, is formed from a single continuous thread that loops back on itself to create a chain-like pattern.
Instead of interlocking two threads, the loop is caught and linked repeatedly — which gives it higher elasticity and flexibility.
Main Advantages:
- Excellent stretch and flexibility – ideal for soft or elastic materials
- High-speed production – fewer interruptions and faster stitching cycles
- Decorative finish – chain-like appearance, perfect for visible seams
- Easier to remove – practical for temporary seams or pattern testing
Typical Applications:
Chain Stitch quilting is preferred for:
- Mattress panels and padding
- Bedspreads and comforters
- Upholstery and seat covers
- Decorative and flexible fabric applications

KEY DIFFERENCES AT A GLANCE
| Feature | Lock Stitch | Chain Stitch |
| Threads Used | Two (needle + bobbin) | One (looped) |
| Strength | Very strong and secure | Moderate, can unravel if broken |
| Elasticity | Low – firm and tight | High – flexible and stretchable |
| Appearance | Identical top & bottom | Chain pattern on one side |
| Speed | Moderate | Higher productivity |
| Maintenance | Simple, minimal oiling | Requires lubrication & tuning |
| Best For | Durable seams, thick fabrics | Soft or elastic fabrics, decorative stitching |
HOW TO CHOOSE THE RIGHT QUILTING TECHNOLOGY
Your decision should depend on product type, fabric characteristics, and production priorities:
- If you need tight, secure seams for heavy-duty or long-lasting products → choose Lock Stitch (YGB Series).
- If your focus is on speed, flexibility, and visual design → choose Chain Stitch (YT Series).
- For maximum efficiency, many manufacturers use both systems in different production lines — Lock Stitch for the core quilting and Chain Stitch for decorative or stretchable parts.
EXPERT TIP FROM BESTFOAM
In today’s competitive textile industry, choosing the right machine is not just about stitch type — it’s about balancing speed, strength, and fabric behavior. Our experts always recommend analyzing your product range, material elasticity, and desired visual finish before making a decision.
