The newly released Cora Soft Fit Disc is now the softest menstrual disc available in the US. Cora’s first menstrual disc, launched as Cora Disc, will now be known as the Perfect Fit Disc, with the addition of a new disc to their line. This post will compare the Perfect Fit Disc and Soft Fit Disc to help you decide which is best for you.
Menstrual Disc Basics
A menstrual disc is a reusable alternative to tampons that is worn internally to catch period blood. Unlike menstrual cups, menstrual discs are suction-free and can be worn during period sex. Discs have a flat fit and are worn higher in the body. Due to where they sit in the body menstrual discs are considered to be “one size fits most” and have a higher chance of fitting more people.

Cora’s Two Menstrual Disc Options | Perfect Fit and Soft Fit
The Cora Disc, now sold as the Perfect Fit Disc, was Cora’s first reusable menstrual disc and the first to offer a finger-width grip for easier removal. Offered in grey, the disc was an immediate success and has an impressive 4.5 star rating on Period.Shop. The Perfect Fit is rated a 3.5 on Period Nirvana’s firmness scale, making it slightly firmer than average; this is a great firmness for new disc users.

Cora’s new Soft Fit Disc is the same size and design as the Perfect Fit but in a softer firmness and new blue hue. Designed to offer a softer option for users who experience bladder pressure or discomfort, the Soft Fit is a 1.5 on the Period Nirvana firmness scale. This makes it even softer than the Nixit and the softest menstrual disc option in the US.

Soft Discs vs Firm Discs
Due to where menstrual discs sit in the body and their design, firmness plays a lesser role in how a disc feels and functions than it does for menstrual cups. That said, depending on your anatomy and sensitivities you might find a firmer or softer disc to be a better experience for you.
Firmer menstrual discs like the Perfect Fit are easier to insert because they have a rigid rim. This makes them easier to push and tuck into place. It can also help the disc stay in place against “pushing” movements of your muscles, thus reducing potential slips during wear. You may have to push harder to make the disc self-empty; a good thing or bad thing depending on who you ask. Firmer discs might create pressure in your body that exhibits in the form of bladder pressure or discomfort.
Softer menstrual discs like the Soft Fit might be more comfortable for sensitive users. They can also be easier to keep folded while inserting. Pushing softer firmness discs into place might be more challenging since they can “squish” during that process. Softer discs can be easier to push out of place for some users, meaning they might be more prone to slips, leaks, and easier to self-empty.
Firm Discs | Soft Discs |
Easy to insert | Easy to keep folded |
Less likely to slip/leak/self-empty | Less likely to apply bladder pressure |
Might cause discomfort/pressure | Might be harder to insert |
Is Cora’s Soft Fit Disc Right For You?
Are you a first time menstrual disc user? If so, I would begin with a menstrual disc that is average in firmness or above because they’re easier as a new user and are less likely to leak. Look for a disc that is a 3 in firmness or above. Cora’s Perfect Fit is a 3.5. Other good first-time user discs include the Hello Disc and Lumma Disc. If you have tried a menstrual disc before it was uncomfortable, or you felt bladder pressure, the Soft Fit Disc might be just what you need. Another consideration would be if you know that you’re a sensitive person or you have certain vaginal/vulvar conditions that mean a softer product is going to be more comfortable.
