This is a 100% Mulberry silk pillowcase (22 momme, 6A grade) in the Cherry Pink color, Queen size. Unboxing and Prep Out of the box, the silk had noticeable deep creases from being folded. I hand washed it and air dried it, but the wrinkles remained. I used a steam iron at approximately 300F with a flour sack towel as a pressing cloth to protect the fabric. It took two passes to get most of the wrinkles out, but the silk held its sheen well throughout the process. Zipper and Construction The zipper tracks are hidden behind a fabric flap so you don't feel the teeth. However, the zipper pull is not fully integrated or tucked away; it hangs free at the end of the track. The pull is small enough that it hasn't been an issue or gotten in the way during use, but it's worth noting it isn't completely "invisible." Fit and Quality The Cherry Pink is a very light, subtle shade. The 22 momme weight feels substantial and opaque. I paired this with a high-loft Sobel Westex Bellazure Duo (feather and down) pillow. The Queen size fits perfectly and the silk stays smooth and cool. Final Thoughts The build quality is solid and the Oeko-TEX certification is a nice touch. To get the best results, you really need to pair this with a high-quality, fluffy pillow to fill out the case properly. On a flat or low-density pillow, it wouldn't look or perform nearly as well. It requires some maintenance with the hand washing and ironing, but the feel is much better than thinner 19 momme options.

Luxuriously Soft & Cooling, But Needs a Wider Opening

Color: 03 - Champagne, Size: Queen, Color: 03 - Champagne, Size: Queen

I really enjoy sleeping on the Beckham Hotel Collection Silk Pillowcase—it has such a silky, smooth feel that makes a noticeable difference in comfort. It feels wonderful against the skin and hair, and I especially love how it helps keep my head cool throughout the night, which leads to a restful sleep. The color choices are also wonderful and look very rich, adding a nice elegant touch to the bed. It’s also held up nicely in the wash, which is always a plus for something this delicate. That said, I’m giving it 4 stars because of the zipper opening design. You lose about 4 inches of usable space at the opening, which makes it harder than expected to insert a pillow. Unlike other zippered pillowcases I own, the ends don’t open wide enough, so I had to squeeze my pillow in—and I actually noticed the stitching starting to pull a bit because of it. A wider opening would make a big difference. Overall, it’s great to sleep on and feels luxurious, but for the price, I do think the design could be improved.

Soft, comfortable and really nice.

Size: Full

This product is of really nice material. It's soft and comfortable, deep pockets and fits my bed perfectly. It's a great product, however, if you're looking for something for back support, this isn't it. It isn't for me anyway - there's no firmness to this topper at all but it is very comfortable.

COMFORTABLE AND WORTH THE MONEY

Size: Queen

Excellent mattress topper. Its thick and paired with my matress provides a high end hotel feel. I have had it for a few months and it has not lost its shape and stays in place. Worth the money. You are definitely getting what you paid for.
