Why Your Bed Never Stays Made
Ordinary bedding is just loose layers. Align™ snaps every layer together.
What's In The Box
Everything you need for a bed that stays made, matched to your picks above.

Align™ Organic Sheet Set
Fitted sheet, flat sheet, and pillowcases. The flat sheet snaps to the fitted sheet, so it never comes untucked.

Align™ Organic Duvet Cover
Snaps to the insert on the top and sides, so it never bunches or shifts.

Align™ Organic Duvet Insert
Oversized for real coverage. Hypoallergenic, easy-care fill that's soft without overheating.
Oversized for real coverage. Plant-based kapok fiber is naturally breathable, light and lofty.
Oversized for real coverage. 700 fill-power European white down for maximum loft and softness.
Bedding Designed to Stay Put
Most bedding is a stack of loose layers that slide apart every time you move. We designed Align™ to fix that, layer by layer.
Every layer snaps into place
Most bedding is just a stack of loose layers, so it slides apart every time you move. Align™ connects each layer with low-profile, hidden snaps so your bed stays together all night.
- Duvet insert snaps into the cover on the top and sides
- Flat sheet snaps to the fitted sheet
- Hidden snaps you will never feel
Change your cover without the fight
No more climbing inside a duvet cover or shaking the insert down into the corners. Lay the insert flat, snap it to the cover, and zip it closed. It stays perfectly in place until you take it out.
No more tug-of-war at 2am
Our inserts and covers are cut oversized for your mattress, so there is plenty to share and no mattress peeking out at the sides.
Certified organic cotton you can feel good about
Our sheets and duvet covers are made from GOTS-certified organic, long-staple cotton and third-party tested, so you know exactly what you are sleeping in.
- GOTS organic certified
- Third-party tested
- Breathable, long-staple cotton
