Six sleep essentials, engineered to work together for your best night's sleep yet.
Your mattress is too firm or has lost its cushioning. The Mellow Cloud Layer transforms it into a cloud-like sleep surface instantly. No more waking up in pain. The dual-layer construction provides plush cushioning on top with stable support underneath. The breathable 3D hollow fibers promote airflow and keep you cool. The quilted stitching keeps the fill evenly distributed. The 360° secure fit stays in place all night long.
Meet the CloudCool™ Cooling Sheet Set, effortless comfort, perfected. It goes on in 30 seconds, stays perfectly in place all night, and stays completely wrinkle-free, no lifting, no slipping, no adjusting. Made with a silky-soft, breathable fiber blend, it helps regulate temperature and wick away moisture so you stay cool, dry, and comfortable all night long. The dual-zone stretch design delivers a smooth, hotel-level finish every time you make the bed.
Soft, plush, and impossibly cozy. It's double-stuffed for that ultra-fluffy, marshmallow feel that hugs you just right. Made with A-Class baby-grade fabric and heat-adaptive vegan fill, it keeps you warm when it's cold and cool when it's not, perfectly balanced for every season.
An everyday bedroom upgrade, crafted from premium ultra-soft brushed fabric for a smooth, breathable feel that's gentle on your skin. Thoughtful details like a hidden zipper closure, four interior corner ties, and envelope-style pillowcases keep your bed looking clean while preventing your comforter from shifting.
Delivers cloud-like softness with breathable comfort night after night. Wrapped in a smooth fabric outer layer with fluffy fill that provides full, cushioned support with a lofty, cloud-like feel. Designed to maintain its shape while delivering gentle responsiveness, helping reduce pressure points and support deeper, more restorative sleep.
Combines ultra-plush velvety softness with an elastic stretch knit construction that delivers gentle, evenly distributed pressure, helping signal your nervous system to shift from alert to at rest. Flip it to the cooling side for warm nights, or the plush side for cooler ones.
Pillow works well so far / I bought it to help with neck pain / it is a very comfortable pillow and I can actually sleep on my side again with it - I LOVE the cooling pillowcase
Everything you need to know about the Build Your Own Bed Bundle.
The Cloud Layer mattress pad, CloudCool™ Cooling Sheet Set, MarshMellow Comforter, MellowSoft™ Duvet Set, Ploof Pillow, and Cloud Throw Blanket.
Yes, every piece in the bundle is machine washable. See the Care section above for specific instructions per item, since a few (like the comforter and throw) need to be washed alone.
Yes. All pieces are hypoallergenic and made with OEKO-TEX® certified or Class A/skin-safe materials.
No. The Cloud Layer, EasyFit Sheet, MarshMellow Comforter, and Ploof Pillow all use breathable, temperature-balancing or moisture-wicking materials designed to prevent overheating.
No, it's optional. The MarshMellow Comforter feels great on its own, but the included MellowSoft Duvet Set is there if you want one, just insert the comforter and secure it with the interior corner ties.
Sizing varies by item (mattress depth for the Cloud Layer, bed size for sheets/comforter/duvet, Standard/King for the pillow, Medium/Large for the throw). Check each product's variant options for exact sizing.
