Smooth, Dry, Made to Fit.

  • Moisture-Managing Fiber

    Lyocell fibers absorb moisture and release it into the air, which helps the fabric feel dry against your skin.

  • Grip-Edge Fitted Sheet

    An elastic, rubber-grip edge helps the fitted sheet hold the corners of mattresses up to 18 inches deep.

  • Smooth, Wrinkle-Resistant

    A smooth 300-thread-count weave that resists wrinkling, so the bed looks made with less effort.

Why Lyocell Belongs on a FORM Bed

  • White FORM TENCEL™ Sheets on a made bed in morning light

    The Layer You Actually Touch

    Every FORM mattress starts with GelGrid™, an open-cell grid designed to let air move. Your sheets sit on top of it and against your skin, so we chose a smooth, 300-thread-count lyocell weave instead of a heavy, high-thread-count cotton.

    A Fiber Made From Wood Pulp

    Lyocell is made from wood pulp that is dissolved and spun into fiber. It absorbs moisture and releases it into the air, which helps the fabric feel dry rather than clammy on warm nights.

  • Folded white FORM TENCEL™ Sheets with pillowcases

    Deep Pockets That Stay On

    Every fitted sheet has 18-inch pockets and a rubber-grip edge. That covers every FORM mattress, from the 10-inch FORM Core to the 15-inch FORM Prime X, with room for a mattress protector underneath.

TENCEL™ Sheets FAQs

Lyocell is a common choice for warm sleepers because the fiber absorbs moisture and releases it into the air, so FORM TENCEL™ Sheets feel dry rather than clammy. Sheets can’t lower your body temperature on their own, so pair them with a breathable mattress and pillow.

Both come from plants. Cotton is a natural seed fiber; lyocell is made from wood pulp that is dissolved and spun into fiber. Lyocell has a smooth, silky hand and handles moisture well, while cotton percale feels crisp and matte. Choose by the feel you prefer.

Full, Queen, King and California King sets include 1 flat sheet, 1 fitted sheet and 2 pillowcases. Twin XL includes 1 flat sheet, 1 fitted sheet and 1 pillowcase. Split King includes 2 Twin XL fitted sheets, 1 flat sheet, 2 pillowcases.

The fitted sheet has 18-inch pockets with a rubber-grip edge. That fits every FORM mattress, 10 to 15 inches tall, with a protector underneath, and most other mattresses up to 18 inches deep.

Only if you have two Twin XL mattresses on a split king base. The Split King set has two separate Twin XL fitted sheets, so each side can move on its own. If one King mattress sits on your base, use the King set.

Machine wash cold on a gentle cycle with a mild detergent, then tumble dry low and remove the sheets promptly. Skip bleach and fabric softener. Cool water and low heat help limit shrinking and pilling.

Washing cold and drying low keeps pilling and shrinkage to a minimum. The 3-year limited warranty covers manufacturing defects such as faulty seams or flawed stitching. Normal wear, fading, pilling and shrinkage aren’t defects.

White and Gray, in every size.

FORM TENCEL™ Sheets are final sale once delivered, like all FORM bedding. If they arrive damaged or defective, contact us and we’ll make it right under the 3-year limited warranty.
