MAINTENANCE RITUAL

Simple care

01 Unpack and expand

Your comforter arrives compressed in a compact box. Simply unpack it and allow a short time for air to circulate through the fibers.

 02 Natural lofting

The interior box-stitching immediately begins expanding, creating that signature marshmallow loft across your entire bed.

 03 Machine wash

When washing is needed, place it in a standard domestic machine on a gentle cycle using mild detergent.

 04 Preserved shape

The stitched compartments keep the fill securely anchored, ensuring it emerges from the wash evenly fluffy every time.

Frequently asked questions

Everything you need to know about sleeping under our cloud-like comforter.

Is a synthetic down alternative really warm enough for cold winter nights?

The double-stuffed fill provides substantial loft and insulation designed for all-season comfort, balancing warmth with breathability. Actual warmth preference naturally varies by individual sleeping habits and ambient room temperature.

 Will it lose its fluff or bunch up in the washing machine?

The sewn-in box-stitch construction compartmentalizes the fill to prevent shifting during machine washing.

 White fabric shows every little stain and mark too easily. How do I manage this?

The comforter is fully machine washable for easy upkeep, and it is also available in darker color variants like gray and sand.

 How do you prevent fill from bunching up over time?

Box-stitch construction anchors the fill securely in place, keeping the comforter consistently fluffy across the whole bed without developing flat spots.

 Will I wake up overheated during the night?

Temperature-balancing, heat-adaptive fibers provide cozy warmth while allowing excess body heat to escape so you stay comfortable.

 Is the fabric safe for sensitive or reactive skin?

Baby-grade OEKO-TEX Class I fabric provides a smooth, gentle hand-feel that is entirely safe for sensitive skin types.
