Kun Collapsible Violin Shoulder Rest — 4/4 Full Size, Made in Canada
The Kun Collapsible Violin Shoulder Rest (SKU: 51706) is a full-size 4/4 violin shoulder rest from one of the most trusted names in violin accessories. Feet fold flat for easy carrying and compact storage, and Kun's patented locking device prevents rotation during playing — keeping the rest securely in position on the instrument without shifting. Lightweight, adjustable, and made in Canada. The Kun Collapsible is the most widely recommended first shoulder rest for violin students and a reliable choice for experienced players who want a compact, practical rest at an accessible price.
Angkor Music — Why Violin Players Use Shoulder Rests, and Why Kun Is the Standard Recommendation
A shoulder rest raises and positions the violin between the chin and shoulder, allowing the instrument to be supported without gripping — either with the jaw or by lifting the left shoulder. Without a shoulder rest, maintaining correct violin hold requires sustained muscular effort that builds tension in the neck, shoulder and left hand. This tension directly interferes with technique: the left hand cannot move freely along the fingerboard when it is partially occupied with keeping the violin in position, and chronic muscular tension from violin playing is a common source of discomfort and injury in players who develop without proper support. A correctly fitted shoulder rest transfers the support role from muscular effort to the rest itself, freeing the left hand to focus entirely on intonation and technique, and reducing the tension that accumulates through incorrect or effortful instrument hold. Not every player uses a shoulder rest — some players, particularly those trained in certain traditional styles, prefer to play without, and some body shapes make this more practical — but for the majority of students and adult learners, a shoulder rest is a fundamental part of a correct and sustainable violin setup. Kun has been manufacturing shoulder rests in Canada since the 1970s and the Collapsible model is their most widely used. It appears on the instruments of conservatory students, amateur orchestra players and teaching studio recommendations worldwide. The reasons are practical — it is well made, adjustable for different body types, light enough not to affect the instrument's balance, and the collapsible feet make it compact to carry in a violin case pocket. The patented locking device is a specific advantage over cheaper alternatives, which can rotate under playing pressure and shift out of position at inconvenient moments. We stock Kun shoulder rests at Angkor Music alongside violin strings, rosin and accessories — contact us for advice on sizing or setup.
Key Features Explained
Collapsible feet:
The two feet that grip the violin's lower bout fold flat when not in use — reducing the rest to a compact profile that fits in a violin case side pocket without taking up the space a fixed-foot rest requires. For students and players who carry their violin regularly, this is a practical daily convenience rather than a minor detail.
Patented locking device:
Kun's locking mechanism prevents the shoulder rest from rotating on the violin during playing. Cheaper shoulder rests with no locking mechanism can shift position under the movement and pressure of active playing — distracting at best, potentially affecting the instrument hold and producing unwanted contact between the rest and the violin body at worst. The locking device keeps the Collapsible exactly where it is set.
Adjustable height and width:
The feet are adjustable for height and the rest is adjustable for width, allowing it to be fitted to different body types — players with longer necks require more height, players with shorter necks require less. Correct height adjustment is important: too high and the instrument is pushed away from the chin; too low and the neck must still work to maintain position. A teacher can help set the correct height for a student's physiology.
4/4 sizing:
This model fits full-size (4/4) violins. Violins are made in fractional sizes for younger students — 3/4, 1/2, 1/4 and smaller — and shoulder rests are sized to match. A 4/4 shoulder rest will not fit correctly on a fractional size violin. If purchasing for a younger student, confirm the violin size before ordering.
Made in Canada:
Kun has manufactured shoulder rests in Canada continuously since the 1970s. The Canadian manufacturing origin is part of the brand's reputation for consistent quality and is referenced by players and teachers as a quality indicator when recommending the brand.
Who Is the Kun Collapsible Shoulder Rest For?
- Beginner violin students setting up their instrument correctly from the outset — the Kun Collapsible is the most widely recommended first shoulder rest by violin teachers
- Adult learners who want reliable support and correct instrument hold without chronic neck and shoulder tension
- Intermediate and advanced players who want a compact, reliable rest that packs down for easy transport
- Parents purchasing for a child who plays full-size (4/4) violin — confirm violin size is 4/4 before ordering
- Players who carry their violin in a case without a dedicated rest compartment, who need the collapsible profile for storage

Frequently Asked Questions
Do I need a shoulder rest to play violin?
Most students and adult learners benefit significantly from a shoulder rest. Without one, the violin must be supported by muscular effort from the neck and shoulder, which builds tension that interferes with technique and can contribute to discomfort over time. A shoulder rest redistributes the support load, freeing the left hand to move correctly on the fingerboard. Some players prefer to play without — particularly those following certain traditional approaches — but for the majority of learners a shoulder rest is a practical part of correct setup. If you are unsure, consult your violin teacher.
What is the difference between the Kun Collapsible and other Kun models?
The Collapsible is Kun's most widely used model and the most recommended for general use. The key distinguishing feature is the folding feet, which reduce the rest to a compact profile for storage in a violin case. Other Kun models (including the Bravo and Original) have fixed feet that do not fold. The Collapsible is the practical choice for most players who carry their violin regularly.
How do I fit the shoulder rest correctly?
The Kun Collapsible attaches to the lower bout of the violin — the wider bottom section of the body. The two feet grip the edges of the lower bout. The height can be adjusted by extending or shortening the feet, and the width can be adjusted to match the lower bout width of your violin. The correct height depends on the player's neck length and shoulder shape — a teacher can help set this correctly for a student. The locking device should be engaged once the correct position is found to prevent rotation during playing.
Will this fit my violin if it is not a standard 4/4?
No — this model is sized for full-size 4/4 violins. Fractional size violins (3/4, 1/2, 1/4 and smaller) require shoulder rests sized to match. Using a 4/4 rest on a smaller violin will not attach securely and may damage the instrument. Contact us at Angkor Music to confirm the correct size rest for your violin.
