Serenity
Experience ultimate serging precision, push-button air-threading simplicity, and effortless fabric control with the Baby Lock Serenity serger! Engineered for garment creators, activewear designers, and textile artists, the Serenity features vertical needle penetration and a powerful engine reaching speeds up to 1,500 stitches per minute. Navigated via intuitive front button controls and digital LED speed indicators, this feature-rich serger offers 4/3/2 thread capacity, flatlocking, rolled hemming, and Baby Lock’s exclusive Wave Stitch. Complete with RevolutionAir® push-button looper and needle threading, the Automatic Thread Delivery™ System, a Snap-On Needle System, a hands-free knee lifter, and a Deluxe Trim Bin, the Baby Lock Serenity turns every edge finish into a masterpiece.
Automatically threads both upper and lower loopers as well as the needles at the press of a single button using jet-air power.
Delivers the exact length of thread required for each stitch automatically, eliminating manual tension dials and guesswork across all fabric types.
Choose whether the needle stops up or down for precision pivoting while adjusting sewing speeds effortlessly via digital button controls.
Swap needles cleanly in seconds without tiny screws or manual tools using a tool-free snap-in mechanism.
Exclusive Tool-Free Snap-On Needle System
Exclusive Tool-Free Snap-On Needle System
Eliminate the frustration of tiny needle screws and manual hex wrenches. Baby Lock’s exclusive Snap-On Needle System lets you insert or release needles quickly and confidently with a simple snap-in motion, speeding up stitch changes with zero squinting.
RevolutionAir® Looper & Needle Air-Threading System
RevolutionAir® Looper & Needle Air-Threading System
Thread your serger completely with the press of a button. RevolutionAir® technology uses air jets to shoot threads instantly through the loopers while assisting needle threading, letting you thread in any order without tweezers or manual thread paths.
Sensor-Driven Automatic Thread Delivery™ (ATD) System
Sensor-Driven Automatic Thread Delivery™ (ATD) System
Achieve balanced, flawless stitch formation across every fabric type without adjusting tension dials. The ATD System calculates fabric thickness and automatically releases the exact required thread length to needles and loopers for perfect seams every time.
Included Deluxe Trim Bin & Scrap Collector

Maintain a pristine workspace while trimming activewear and garment seams. The included low-profile Deluxe Trim Bin fits alongside the machine bed to catch cut fabric trimmings without obstructing access to machine adjustment dials.
Hands-Free Presser Foot Knee Lifter Bar
Hands-Free Presser Foot Knee Lifter Bar
Manage bulky fabrics, curves, and precise seam alignments smoothly without taking your hands off your workpiece. A slight movement of your knee raises and lowers the presser foot for seamless fabric positioning.
Compact Overlock Specialty Attachment Table
Compact Overlock Specialty Attachment Table
Expand your decorative finish options with a stable attachment foundation. The Compact Overlock Table allows quick mounting of compatible specialty attachments like the Fabric Guide and 36mm Double Fold Bias Binder for clean, bound edges.
Spacious 2" Bed Workspace Clearance
Spacious 2" Bed Workspace Clearance
Guide bulky garments, wide hems, quilt layers, and home decor projects comfortably. Providing a generous 2 inches of workspace to the right of the needle, the expanded bed area eliminates fabric crowding and drag.
Precision Drop Feed Mechanism
Precision Drop Feed Mechanism
Take control of fabric alignment for tricky starts and detailed sectioning. Lowering the feed dogs disengages automatic fabric movement so you can position materials under the needle bar with exact precision.
Digital Speed Control & Needle Up/Down Keys
Digital Speed Control & Needle Up/Down Keys
Fine-tune machine performance right from the front control panel. Adjust stitching speed with touch buttons monitored by LED speed indicators, and set the needle bar to stop up or down for precise pivoting.
Cover Stitch & Overlock Chaining-Off Capability
Cover Stitch & Overlock Chaining-Off Capability
Start and finish seams cleanly without thread bunching or unraveling. The Serenity forms a continuous thread chain off fabric ends for overlock and cover stitches, allowing you to move from seam to seam and trim chains easily using the side cutter.
Fine-Tuning Dials for Blade, Length & Width
Fine-Tuning Dials for Blade, Length & Width
Adjust seam parameters easily using three dedicated rotary dials. Lock the cutting blade for decorative work, adjust stitch length from 0.75mm to 4mm for rolled hems, and tune stitch width from 1.5mm to 7.5mm for heavy knits or light wovens.
Fold-Out Storage Compartment & Magnetic Tray
Fold-Out Storage Compartment & Magnetic Tray
Keep essential notions organized right inside the spool stand. A fold-out door stores spare needles and feet, while a built-in magnetic tray holds loose pins and dropped needles securely in place.
