THXSILK’s strongest documented strength is real mulberry silk at prices well below luxury bedding brands. Its 22 momme pillowcases are made from Grade 6A+ mulberry silk on both sides, certified to OEKO-TEX Standard 100, and sell for around $36 at major retailers. On Trustpilot, THXSILK holds a 3.8 TrustScore from 1,926 reviews, with 70% rated five stars. Satisfied buyers say its silk sheets “feel incredibly soft, smooth, and luxurious,” and a Belgian shopper praised “High quality silk products. No hidden transport costs or customs fees.” THXSILK is a silk bedding and sleepwear brand, with a U.S. contact address in Denver, that says it has worked in silk for more than two decades. It sells silk pillowcases, sheets, duvet covers, silk-filled comforters, sleep caps, eye masks and accessories through its own international and German sites, Amazon and Walmart. What sets it apart is the range of silk weights (19, 22, 25 and 30 momme), hidden-zipper pillowcases, hyaluronic acid-infused options and silk-filled duvets, at prices that undercut most premium silk brands.
The range is broad. The best-selling 22 momme hyaluronic acid (HA) silk pillowcase, with a hidden zipper and both sides in 6A+ mulberry silk, runs about $35.99 to $41.99 at Walmart depending on size. The 19 momme pillowcase starts around $29.99 (about $34.99 for king), and the 19 momme silk contour cervical pillowcase is about $31.99 to $37.99. Pillowcases come in around eleven colors, including Pearl White, Champagne, Charming Pink, Emerald Green and Navy. Sheets come in 19, 22 and 25 momme weights. One Swiss buyer paid €280 for a 25 momme 180×200 cm fitted sheet. The range also includes 19 momme silk duvet covers, 6A mulberry silk-filled comforters in summer and winter weights, silk sleep caps and a 30 momme pillowcase. THXSILK says its products are OEKO-TEX and ISO 9001 certified. It offers a 30-day return and exchange policy, frequent discounts, and replies to 80% of negative Trustpilot reviews, typically within 48 hours.
The honest caveat: 14% of THXSILK’s Trustpilot reviews are one-star. One buyer said her 22 momme sheet set began “pilling and showing visible signs of wear” within weeks and was denied a refund one day past the 30-day window. Another wrote, “I never received my order,” after a parcel shipped without a signature requirement.

We analyzed THXSILK’s Trustpilot profile (1,926 reviews, a 3.8 TrustScore, 70% five-star and 14% one-star, with an 80% reply rate to negative reviews), its Walmart product listings and prices, and a competitor’s published comparison of 22 momme pillowcases. Note that THXSILK invites customers to review, and some retailer reviews are marked “Incentivized.” GlossGirly has no commercial relationship with THXSILK that affects this verdict. Skin and hair note: silk’s smooth surface can reduce friction, but claims that pillowcases prevent breakouts or wrinkles aren’t well established. If you have sensitive skin, wash new silk before use, and stop using it if irritation occurs.
THXSILK’s core product is mulberry silk, the finest commercial silk fiber, which it sells in Grade 6A+ quality. Momme measures silk weight and density. Higher momme means more silk and thicker fibers, which generally means more durability and a richer feel. THXSILK offers 19 momme for budget buyers, 22 momme as the sweet spot, 25 momme for sheets and a 30 momme pillowcase for maximum density. Its pillowcases use silk on both sides, plus a hidden zipper that keeps the pillow from slipping out. The HA line adds hyaluronic acid, which the brand markets for hair and skin. THXSILK says its products carry OEKO-TEX Standard 100 certification (tested for harmful substances) and are made under an ISO 9001 quality system. Many buyers confirm the luxurious, smooth feel. A minority question it: one Canadian buyer reported static, friction, skin irritation and a strong chemical smell on a pillowcase, and doubted it was pure silk. THXSILK replied asking for her order details.
Beyond pillowcases, THXSILK is one of the few affordable brands offering a full silk bed. Its range includes fitted and flat sheets in 19, 22 and 25 momme, silk duvet covers, and comforters filled with 6A mulberry silk in seasonal weights. A satisfied U.S. buyer called his sheets soft, smooth and beyond expectations. One shopper ordered a summer silk-filled comforter and a 19 momme duvet cover and received both about three weeks later. Couples and gift-givers are frequent buyers, and one shopper bought sets for herself, a relative and her vacation home. Silk sleeps cool and feels gentle on hair, which is why sleep caps and pillowcases are popular with curly and textured hair. The caveats are care and durability. Silk needs cold, gentle washing with pH-neutral detergent, air drying and no bleach. One buyer said her 22 momme sheets pilled within weeks. THXSILK responded that friction, usage habits and care methods can all affect wear.
THXSILK’s one-star reviews concentrate on parcels and policy. A pregnant buyer in Switzerland said her order never arrived, that it shipped without a signature requirement and without proof of delivery, and that a promised refund never came. A German customer reported the same missing parcel. A U.S. reviewer described being sent through endless hoops for a refund. THXSILK replies publicly to most of these, usually asking for an order number, and some buyers report quick fixes. A German shopper said a delivery problem was resolved “real quick.” The 30-day return window is enforced strictly. One customer who reported pilling on day 31 was offered a promo code instead of a refund. Other friction points include an Amazon order where the buyer said THXSILK redirected him to a third-party seller, a request for repair fabric that was declined, and a Swiss buyer who found the same fitted sheet about €100 cheaper on Amazon. THXSILK explained that its Shopify and Amazon stores run different promotions.
On price, THXSILK is hard to beat. A 22 momme, two-sided mulberry silk pillowcase for about $36, or a 19 momme pillowcase from about $30, costs a fraction of luxury silk brands. A competing silk company’s comparison listed THXSILK’s 22 momme queen pillowcase at $59.98 retail, against $75 for its own. Sheets and comforters are pricier, but still competitive for real silk. Buyers should check prices across channels, since one shopper found the same sheet much cheaper on Amazon. There are some trust questions worth knowing. A reviewer said THXSILK’s on-site sleep-cap reviews repeated identical text under different names, which THXSILK said it didn’t do. A U.K. silk maker alleged that a linked manufacturer used her product photos on Alibaba. Retailer listings also show some reviews marked as incentivized. Our advice is to buy from a channel with strong buyer protection, pay by card or PayPal, and inspect and wash silk immediately so any problem surfaces inside the 30-day window.
This is the flagship: Grade 6A+ mulberry silk on both sides at 22 momme, OEKO-TEX Standard 100 certified, with a hidden zipper and an HA treatment the brand markets for hair and skin. It comes in standard (20″x26″), queen (20″x30″) and king (20″x36″) sizes in colors such as champagne, charming pink, light blue, gray and black. It’s best for anyone trying silk for the first time, especially people with curly or color-treated hair. Treat HA and anti-wrinkle claims as a bonus rather than proven benefits. Wash on a cold, gentle cycle in a mesh bag, and air dry.
The 19 momme pillowcase is THXSILK’s budget entry. It’s lighter than 22 momme but still 100% mulberry silk on both sides with a hidden zipper. It’s best for gifts, guest rooms, travel, or anyone who wants silk’s smooth, cool feel at the lowest price. Lighter silk is slightly less durable, so wash gently and avoid rough fabrics against it. Rotating two pillowcases extends the life of each. Inspect seams and zippers on arrival so you can exchange within 30 days if needed.
The 25 momme fitted sheet sits at the luxury end of THXSILK’s range. Its denser silk offers a richer drape and, in theory, longer life than lighter sheets. It comes in Pearl White and other colors, and in European and U.S. sizes. It’s best for hot sleepers who want full-body silk and buyers ready to commit to careful laundering. Compare prices on THXSILK’s site and Amazon before buying, since buyers have found sizable differences between the two. Wash gently and check for pilling within the first few weeks, since the 30-day return window is strictly enforced.
THXSILK’s silk-filled comforters use 6A mulberry silk as the filling, in seasonal weights including a lighter summer version. They pair with its 19 momme silk duvet covers. Silk filling is lightweight, breathable and temperature-regulating, which suits hot sleepers and people who find down too warm. It’s best for buyers creating a full silk bed. Delivery can take a few weeks, so order well before you need it. Use a duvet cover to protect the filling, and air the comforter regularly rather than washing it.

“Send you through 1000 hoops for a refund.” — Lacy White, Trustpilot reviewer (US, 1 star, Lost order)
THXSILK is worth it for shoppers who want real, OEKO-TEX-certified mulberry silk pillowcases and bedding at prices well below luxury brands. The 22 momme pillowcase is the standout. Compare prices on THXSILK’s site and Amazon, pay with buyer protection, and inspect and wash items as soon as they arrive, since the 30-day return window is strict. If a guaranteed, painless return process matters most, consider a higher-rated silk competitor.

THXSILK sells its products as 100% Grade 6A+ mulberry silk, OEKO-TEX Standard 100 certified. Most buyers praise the feel, though a few report static or smells.
Yes. THXSILK has 1,926 Trustpilot reviews with a 3.8 score and 70% five-star, but 14% are one-star, mostly about lost parcels and refunds.
THXSILK accepts returns and exchanges within 30 days. Reviewers report the window is strictly enforced, even by one day.
22 momme offers the best balance of softness, durability and price. 19 momme is cheaper, and 25 to 30 momme is denser and longer-lasting.
Wash cold on a gentle cycle or by hand with pH-neutral silk detergent in a mesh bag, avoid bleach, and air dry away from direct sun.
THXSILK makes real mulberry silk unusually affordable. Its 22 momme, two-sided pillowcases with hidden zippers, OEKO-TEX certification and wide range of colors, weights, sheets and silk-filled comforters give shoppers a full silk bed at fair prices. Seventy percent five-star reviews from nearly two thousand buyers describe soft, smooth, luxurious bedding, and the brand publicly responds to most complaints.
The risks are in fulfillment and durability. Lost parcels without signature requirements, a strictly enforced 30-day return window, reports of pilling, price gaps between channels, and a few trust questions explain the 14% one-star share. Buy with buyer protection, compare prices, and inspect your silk right away. On those terms, THXSILK is a good-value recommendation for first-time silk buyers.
