Mompmuir Breast Pump Cushion – Size S (2pc) for Flange 21–23mm | Elastic Nipple Flange Inserts

Meet your pumping companion: Mompmuir Breast Pump Cushion

Breast pumping can bring moments of discomfort, especially when flange fit isn’t quite right. The Mompmuir Breast Pump Cushion is designed by moms for moms to offer a soft, flexible layer between skin and pump. Crafted from BPA-free, food-safe silicone-like material, these cushions feel light and pliable, turning a rigid plastic interface into a gentler, more forgiving surface. The result is a more comfortable pumping experience that adapts to your shape without compromising your routine.

These cushions slip into your flange the way a cushion would slip onto a seat—with minimal effort and a clear view. The material’s slight friction helps the cushion maintain a secure seal, while its cone-like shape makes insertion and removal easy. Because the cushions are transparent, you can align them precisely with your flange and your body’s natural contours.

Key sizing and fit

The cushion set is available in multiple sizes to cover different flange diameters. Specifically, Size S is designed to reduce flange diameter by about 2 mm, making it a good match for moms using 19–21 mm interfaces. The cushions are also compatible with most breast pump brands and accessories on the market, working with flange sizes 21–23 mm when used as part of the 2-piece set.

What this means in practical terms is a more customized fit that can help you align the flange with less effort, potentially reducing movement and improving comfort during pumping sessions. The cushions are a lightweight, clear insert, so you can focus on your pumping routine rather than fighting with fit or irritation.

Material, care, and durability

Made from BPA-free, food-safe plastic, the cushion set is designed for repeated use. To preserve the cushion’s integrity, avoid exposing it to boiling water or steam sterilization. Instead, wash by hand with warm water and a gentle soap, then air dry. The clean, clear material is easy to inspect for wear and tear between sessions.

• ENHANCED COMFORT: 2pc clear breast pump cushions provide a soft, stretchy layer for a more comfortable pump.
• FIRM BUT FLEXIBLE: The cushion’s slightly friction surface helps seal while retaining its cone-shape for easy insertion and removal; reduces flange size by ~2 mm.

• AVAILABLE IN MULTIPLE SIZES: Four sizing options, including Size S for 19–21 mm flanges, to match your natural shape.
• COMPATIBILITY & SAFETY: BPA-free, food-safe material compatible with most major brands.

In real-life use, moms report a calmer pumping experience when the cushion is used to tailor flange fit, especially on days when sensitivity is higher or when switching between sizes. It’s a thoughtful accessory that can help you customize your setup without changing your core routine. While not a guarantee of outcomes, the cushion aims to offer a smoother, more controlled pumping moment for those who value fit and comfort. If you’re testing new flange configurations, this two-piece set gives you a tangible, low-friction option to explore.
