10 Best Coverstitch Sergers 2025 in the United States

The Brother Coverstitch Serger 2340CV is a solid choice for anyone needing a reliable machine dedicated to cover stitching, especially when working with stretchy fabrics. One of its notable strengths is the sturdy metal frame, which enhances durability and stability during operation. It offers a high sewing speed of up to 1,100 stitches per minute, allowing users to complete projects efficiently. The machine features a variety of stitch types, including tri-cover and narrow cover stitches, with adjustable widths from 3 to 6 millimeters, making it versatile for different fabric thicknesses.

Ease of use is emphasized with a color-coded threading system and a fast thread looper, which simplifies the threading process—a big plus for beginners or those who find threading challenging. The inclusion of accessory feet like the hem sewing presser foot adds to its functionality, allowing you to tackle various projects without needing to purchase additional items.

This serger is ideal for home sewing enthusiasts who frequently work with knits and want a reliable machine that can produce professional-quality hems and finishes. However, those with heavier fabric needs may need to consider alternative options.

The Brother AIR1800 Air Serger is a great option for those looking to enhance their sewing projects with professional-quality finishes. Its standout feature is the Jet Air Threading technology, which makes changing threads incredibly easy and quick—perfect for users who may find traditional threading methods frustrating. With the ability to work with 2, 3, or 4 threads, it allows for versatile stitching options such as flatlock, overlock, and rolled hems, making it suitable for a variety of fabrics, including stretchy materials. The color-coded thread guides are helpful for keeping everything organized, which can reduce the learning curve for beginners.

In terms of practicality, the brightly lit work area is a thoughtful addition, especially when dealing with darker fabrics where visibility can be an issue. The AIR1800 is designed with speed in mind, catering to users who want to accomplish their sewing tasks efficiently.

There are some considerations to keep in mind. Despite its advanced features, the machine is intended for use in the US at 120 volts, which could be a drawback for international users or those who might need to use it elsewhere. Additionally, while the AIR1800 excels with stretchy and specialty fabrics, those who primarily sew heavier materials may find that it’s not the optimal choice for their needs.

The Brother ST4031HD Serger is designed for users seeking a robust and efficient serger for various sewing projects. Its durable metal frame ensures it can handle heavy-duty tasks, making it ideal for those working with thicker fabrics or requiring a more stable machine. The serger offers a high maximum speed of 1,300 stitches per minute, allowing users to complete projects more quickly. This is a significant advantage for both hobbyists and professionals who need to maximize their productivity.

Another user-friendly feature is the color-coded threading system, which simplifies the often daunting task of threading the machine. This is particularly helpful for beginners or those who prefer an easy-to-use serger. The inclusion of three different accessory feet (standard, blind stitch, and gathering feet) along with a large extension table provides versatility and support for larger projects.

However, the serger is limited to use within the US due to its 120-volt specification, which might be a drawback for international users. Another point to consider is the weight of the machine, which at 17.64 pounds, might be cumbersome for some users who need to move it frequently. Despite these limitations, the Brother ST4031HD Serger is a strong candidate for anyone in the US looking for a reliable, high-performance serger that can handle a variety of fabrics and sewing needs.
