FAQs

How does the Align Duvet System work?

Snaps along the top and sides of your insert connect to the inside of your cover. This keeps the fill evenly distributed. No bunching, no shifting, no morning fluffing.

Is it hard to put the insert in the cover?

Easier than traditional duvets. Lay the cover flat, place your insert on top, snap the connection points and flip. The snaps do the work of keeping everything aligned.

Can I use my existing duvet insert?

The Align Duvet System requires both a Sierra Dreams cover and insert. Our snaps are designed to work together. Our covers work as beautiful standalone covers, but you'll miss the stay-in-place benefit.

What's the difference between your insert fills?

Kapok is our plant-based option. Naturally hypoallergenic, temperature-regulating and incredibly light. Down offers classic warmth with 700-fill-power European white down. Down Alternative provides a hypoallergenic option with a down-like feel at a lower price point.

What is kapok?

A natural plant fiber from the kapok tree. It's lighter than down, naturally hypoallergenic and regulates temperature beautifully. Cool in summer, warm in winter.

Is kapok good for allergies?

Yes. Kapok is naturally resistant to dust mites and hypoallergenic. It's an excellent choice for allergy sufferers who want a natural fill.

How does kapok compare to down?

Kapok is lighter and sleeps cooler. Down is warmer and has that classic lofty feel. Both are natural and high-quality. It comes down to your sleep preferences.

Is your kapok organic?

Yes. Our kapok is organically grown without pesticides or synthetic fertilizers.

Does the Align snap system hold up in the washing machine?

Absolutely. We use YKK snaps—the same industrial-grade hardware found in premium outdoor gear from brands like Patagonia and The North Face. These snaps are rated for thousands of cycles, which means they're built to outlast the fabric itself. Every attachment point is reinforced with internal backing and extra stitching to prevent any fabric stress. The low-profile design also means they won't snag on other items in your wash. Translation: wash your Sierra Dreams bedding as often as you'd like. The Align system can handle it.

Will the snaps rust or corrode over time?

No. YKK snaps are corrosion-resistant by design—they're engineered to remain functional and rust-free even with frequent exposure to water and detergent. Unlike cheaper metal fasteners that can oxidize or leave marks on fabric, our snaps maintain their finish and function wash after wash, year after year.

Do the snaps get looser over time?

No. The snap-and-hold mechanism maintains its tension over thousands of cycles. You won't experience that frustrating "loosening" that happens with cheaper fasteners. When you snap your sheets or duvet together on day one, that's how secure they'll feel on day 1,000.

Will the fabric tear around the snap attachment points?

This was one of our primary engineering concerns, and we solved it. Each snap attachment point features internal reinforcement and additional stitching that distributes stress across a larger area rather than concentrating it at a single point. The result: no reported issues of tearing, fraying, or fabric degradation around the snaps, even after extended use.

What washing temperature should I use for Sierra Dreams bedding?

Any normal washing temperature works perfectly—cold, warm, or regular. The YKK snaps and our organic cotton can handle standard home laundering without any special treatment. For drying, we recommend low to medium heat to preserve both the fabric softness and snap tension over the long term. No delicate cycle required.

Will the snaps damage my washer or dryer?

No. The snaps are low-profile and won't damage your machine's drum. If you're sensitive to noise, here's a pro tip: wash your duvet cover inside out or snap the cover to itself during the wash cycle. This muffles the sound of snaps against the drum wall. But to be clear—this is a noise preference, not a durability requirement.

How long will the YKK snaps last?

YKK snaps are rated for thousands of attachment cycles. In practical terms, the snaps will outlast the fabric. You'll replace your sheets due to normal wear long before the snap mechanism shows any sign of degradation. We chose YKK specifically because we wanted hardware that would never be the weak point in your bedding.
