C.S. Osborne No. 409 4-Inch Bayonet-Point Mattress Needles
When to choose it
Choose this No. 409 when a mattress repair calls for the maker’s long bayonet point on a curved needle. The four-inch variant is 15 gauge. That shape and point are the useful differences to check when you are choosing beside a round-point upholstery needle.
Osborne measures the size across the curved needle. Check the room to turn beside the seam rather than using four inches as a through-stitch depth. If you need to cross the padding in a straight path, compare a long straight needle with the right point for your material.

Questions about this product
Which other size does Osborne list?
Osborne lists an eight-inch version at 14 gauge. Check both changes when deciding whether you need a larger curve.
Can I read four inches as the eye-to-point distance?
Use the manufacturer’s measurement across the full curve. It describes overall size rather than that gap.
What if the material calls for a round point?
Compare a documented round-point model, then check the arc and gauge separately.
