Description

Sei shams have a 1/2" micro-flange with double stitch detail and an envelope closure to hold your pillow insert snugly in place.

Contrasting white double stitch detail.

Sham vs. Pillowcase

Shams and Pillowcases are both used to protect pillow inserts, but there are a wide variety of constructions. Typically, shams are more fitted and employ some method of closure to keep the pillow in place, whereas pillowcases loosely encase the pillow and are open on the side.

Fabric

Sei is our highest thread count fabric at 600 TC. We are not myopically focused on thread count at MATTEO. Thread count is one among many measurements of quality in the world of bed linens. The most simple definition of thread count is to take a pair of scissors and cut out a square inch of fabric and count each individual yarn (or thread). This is the thread count and, as such, thread count is simply a definition of the density of the weave. It does not take into consideration the softness of the raw cotton used or the size and smoothness of the yarn, nor does it measure the balance of the weave. Focusing only only thread count is similar to deciding which beer to drink by only measuring its alcohol content.

We have not yet gone above 600 thread count at MATTEO because higher counts typically produce a stiff and dense fabric that does not move or breathe.Â All sateens (or satin) fabrics have a face which is softer and a backside which is rougher. This is what creates the "silky" feel that customers love so much. And our customers love Sei because it is one of the purest, softest, and silkiest fabrics on the market.

Care Details

Wash

Wash should be separated into light & dark colors. Do not overload machine as this will damage long cotton fibers. We recommend a lukewarm wash cycle with a gentle detergent & a cool rinse.

Bleach may be used on white cotton bed linens only. Avoid using products that contain whitening agents such as chlorine bleach, alpha hydroxy acids and benzoyl peroxide on garment-dyed items. The reactive dyes used for garment-dyeing are not resistant to these whitening agents.

The largest challenge with garment-dyeing is the truth that it is an art, and not a science. We must allow for a shade variation of +/- 10% from dye-lot to dye-lot.

Drying

Tumble dry with low heat.Remove bed linens promptly from the machine to reduce wrinkling. For best results, line dry.

Ironing

We at MATTEO tend to prefer a lived-in look, as such, you don't find us ironing our sheets too frequently. If you prefer a crisp looking bed, our cotton bed linens should be pressed while slightly damp using the Lightweight Cotton or Medium setting.

Frequently Asked Questions

What fabric and thread count is the Sei Sham made from?

The Sei Sham is 100% cotton in a sateen weave at 600 thread count, garment-washed and designed by MATTEO in Los Angeles. Sei uses the same 120/2 Ne yarn in both warp and weft, which produces the sham's characteristic silky face and uniform drape — the same construction standard used in hotel-grade pillow shams.

What is the difference between a sham and a pillowcase?

A sham is more fitted than a pillowcase and uses a closure to hold the pillow insert in place. The Sei Sham has a 1/2" micro-flange with double stitch detail and an envelope closure, giving the bed a tailored, finished look that an open-sided pillowcase does not.

What sizes does the Sei Sham come in?

The Sei Sham is available in Queen (20 x 30 inches / 51 x 76 cm), King (20 x 36 inches / 51 x 91 cm), and Euro (26 x 26 inches / 66 x 66 cm). Euro shams are sold at the same price as King shams.

How do I wash and care for the Sei Sham?

Machine wash in lukewarm water with a gentle detergent, separating light and dark colors. Tumble dry on low heat and remove promptly to reduce wrinkling; for garment-dyed colors, avoid chlorine bleach, alpha hydroxy acids, or benzoyl peroxide, as these will strip the reactive dye.
