Bedsure Cooling Duvet Cover King, Eucalyptus Lyocell Cotton Hybrid, Forest Green Review (2026)

Who this duvet cover is for

Bedsure positions this king duvet cover for hot sleepers who want a natural fiber blend rather than plain cotton or synthetic microfiber, using a mix of eucalyptus derived lyocell and cotton that the brand describes as moisture wicking and breathable. The forest green colorway sets it apart from the more common white, beige, or pastel duvet covers in this category, giving it more visual depth and a better ability to hide everyday marks than a lighter shade would. Because it is a king size set, it suits anyone with a king or Cal King duvet insert already on hand, since the cover itself does not include a comforter. Shoppers who prefer crisp white or neutral bedding, or who want an all-in-one comforter rather than a separate cover and insert, should look elsewhere in Bedsure's lineup or at a bundled comforter set instead.

The lyocell and cotton hybrid fabric

Lyocell is a fiber made from wood pulp, in this case eucalyptus, through a closed-loop manufacturing process that is generally considered more environmentally efficient than standard rayon production, and it is prized in bedding for a soft, silky hand feel and natural breathability. Blending it with cotton in this hybrid fabric aims to combine lyocell's smooth, cool touch with cotton's familiar durability and easy care compared with a pure lyocell sheet. Both fibers are naturally moisture wicking, which the brand says helps pull moisture away from the body rather than letting it sit against skin, a useful property for anyone who tends to run warm overnight. This is a different approach from synthetic cooling covers that rely on polyester wicking finishes rather than natural fiber breathability.

What is included and how it fits

The king set includes one duvet cover along with two matching pillow shams, but it does not include a comforter or duvet insert, so buyers need to already own one or purchase one separately to use this as a finished bed. The duvet cover uses an interior closure, typical of duvet covers in this category, to keep an insert from bunching up or shifting inside the cover overnight. Because this is sold as a cover set rather than a filled comforter, it also works well for anyone who wants to swap covers seasonally while keeping the same insert year round, changing the color and weight of the bedding without buying a new comforter each time.

Caring for a deep, saturated color

Bedsure states the fabric is machine washable at low temperatures on a gentle cycle and is designed to resist hardening, pilling, and wrinkling after repeated washes. Deep saturated dyes like this forest green are generally more prone to fading under hot water or high heat drying than lighter pastel shades, so sticking to a cooler wash and a lower dryer setting will help the color stay rich for longer, even though this is a general laundering principle rather than a claim specific to this listing. Washing dark colors separately from light bedding for the first few cycles is also a reasonable precaution with any newly dyed fabric.

How it compares in the guide

In the site's best cooling duvet covers guide this forest green king set ranks third of six with a score of 7.8 out of 10, behind the PHF French flax linen duvet cover at 8.4 and just ahead of Bedsure's own cotton and bamboo rayon blend king cover in petal pink at 7.6. Compared with the YIYEA Arc-Chill cooling duvet cover at 7.4, which leans on an active cooling fiber treatment, this Bedsure lyocell hybrid relies on natural fiber breathability rather than a cooling finish, which tends to be a gentler, longer lasting form of temperature regulation than treated fabrics that can wear off over repeated washes.
