About this item

  • Extended-Sitting Comfort--High-density memory foam contours to the body for balanced support and helps reduce pressure around the tailbone, hips, and lower back during work, driving, gaming, or other long sitting sessions.
  • Ergonomic U-Shaped Design--A central coccyx cutout helps limit direct tailbone pressure, while the 5.8-inch raised rear and sides provide contoured support around the hips and thighs for a more stable sitting position.
  • Large Size & Non-Slip Base--Measures 20 x 16 x 5.8 inches and is designed for users weighing 100-220 lb. The full-bottom rubber surface helps keep the cushion stable on office chairs, gaming chairs, wheelchairs, and car seats.
  • Breathable, Washable Cover--The mesh cover promotes airflow and helps reduce heat buildup during long sitting sessions. It removes easily and is machine washable for convenient care; do not machine wash the memory foam core.
  • Comfort Across Daily Routines--Lightweight design makes the cushion easy to move between home, office, and vehicle seating. Suitable for professionals, drivers, gamers, and older adults; check seat dimensions before purchase.

    I like that Maternelle offers products for pregnancy, postpartum, and nursing rather than focusing on only one stage. The items I chose have been practical for my daily routine, and the descriptions helped me select the right styles and sizes.

FAQ

What types of products does Maternelle offer?

Maternelle offers maternity clothing, pregnancy comfort products, postpartum wear, nursing accessories, hospital and travel organizers, exercise accessories, journals, keepsakes, and gifts for expecting and new mothers.

How do I choose the correct size for maternity or nursing clothing?

Please check the size chart and garment measurements provided on each product page. Sizing can vary by manufacturer, so we recommend comparing your current bust, waist, hip, and inseam measurements rather than relying only on your usual size.

Are all products suitable for every stage of pregnancy?

Not necessarily. Suitability may depend on your stage of pregnancy, measurements, health circumstances, and the product’s intended use. Review the product description, instructions, size information, and warnings before purchasing or using an item.

Are Maternelle products medically approved?

Maternelle primarily offers general lifestyle, clothing, organization, and comfort products. Unless expressly stated and verified on the individual product page, products are not medical devices and are not intended to diagnose, treat, cure, or prevent any medical condition.

Should I consult my healthcare provider before using a support or exercise product?

Yes. Consult a qualified healthcare professional before using belly belts, pelvic bands, compression garments, posture supports, exercise balls, resistance accessories, heat products, or starting a new exercise routine—especially if you have pain, complications, circulation concerns, or activity restrictions.

How should I care for maternity clothing and fabric accessories?

Care instructions vary by material and manufacturer. Always check the product label and listing before washing. Some items may require cold washing, gentle cycles, air drying, cover removal, or spot cleaning.

Do pregnancy pillows include removable covers?

Some pregnancy pillows include removable, washable covers, while others may sell the cover separately. Check the product description, included components, dimensions, and pillow shape before ordering.

Are breast pumps or feeding bottles included with organizers and carrying bags?

Only when specifically stated in the product description. Pumps, bottles, ice packs, and other accessories shown in product images may be for demonstration purposes and sold separately.

Can nursing covers or pregnancy pillows be used for infant sleep?

No. Adult pregnancy pillows and nursing covers should not be used as infant sleep products. Always follow current safe-sleep guidance and the manufacturer’s instructions, and keep loose fabric, pillows, and accessories away from an infant’s sleep area.

How can I check whether a product will fit or work with something I already own?

Compare the listed dimensions, attachment method, model compatibility, capacity, closure type, and included parts with your existing item before ordering. If compatibility is unclear, contact us with the relevant measurements or model information before purchasing.
