A matched four-piece mulberry silk bedding set at 25 momme: duvet cover, fitted sheet, and two pillow shams. It runs $899.99 for Full up to $1,229.99 for California King, verified August 2, 2026.
THXSILK is a mulberry silk bedding brand, and the Classic Silk Bedding Set is its matched four-piece set: one duvet cover, one fitted sheet, and two pillow shams. The brand lists the fabric as 100% mulberry silk at grade 6A and 25 momme, woven to 750 thread count, with an invisible zipper on the duvet cover and 8 interior corner ties to hold an insert in place. The listing carries an OEKO-TEX Standard 100 mark, though no certificate number is published on the page. The duvet insert itself is not included, and a laundry bag is thrown in.
Momme is the weight measure for silk, and it is the number that separates a substantial set from a thin one. For reference, the Promeed silk we already list is sold in 22, 25, and 30 momme, so 25 sits in the middle of what is commonly offered for bedding. Pricing here is by size and identical across all seven colorways: $899.99 Full, $949.99 Queen, $1,049.99 King, and $1,229.99 California King, verified against the brand's own product data on August 2, 2026. All 28 variants were in stock that day, and the compare-at price matched the list price on every one, so nothing was discounted. Sizes stop at Full on the small end. The published size chart includes Twin dimensions, but no Twin variant is actually sold. Fitted sheets are listed with a 16 inch pocket across every size.
Against what we already list, this is the top of the silk shelf. Promeed's single mulberry silk pillowcases run $55 to $104, and its full silk sheet sets ran $446 to $760 when we verified them in July 2026, so THXSILK's $949.99 Queen sits above the top of that range. We have not put the two sets side by side on piece count or momme, so treat that as a price gap and not a like-for-like verdict. The other premium bedding layers in this category do different jobs: the GroundLuxe grounding sheet is $169.95 flat and exists for the earthing circuit rather than the hand feel, and the Sleep & Beyond myWoolly topper at $469 to $749 changes how the mattress feels rather than the surface you touch. If your reason for buying is the fabric against skin and hair, silk is the right shelf and this is the fuller version of it.
Where it gives ground. We have not tested this set. Everything above is read off the brand's product data and product page. Silk asks for care: THXSILK specifies cold machine wash on gentle, inside out with the zipper closed, a detergent made for silk, air dry away from direct sunlight, and no tumble dry. The sticker is not the finished bed either, since the duvet insert is a separate purchase. Delivery is quoted at 6 to 12 business days after a 1 to 2 business day handling window, which is slow next to domestic bedding brands. Returns are 30 days, and as of August 2, 2026 we found no warranty statement and no country of manufacture anywhere on the product page. The 6A grade is a supplier designation rather than an audited third-party mark, so read it as THXSILK's own grading. And the brand's description of the fabric as cooling, breathable and skin-friendly, and as reducing friction on skin and hair, is THXSILK's claim about its own product. We have not measured any of it.
Buyers who already know they want silk bedding and want the matched four-piece set at 25 momme rather than testing the material with a single pillowcase first, in Full through California King.
You want to try silk for under $100 first, you need a Twin, you expected a duvet insert in the box, or gentle-cycle-and-air-dry care is more than you want to give your bedding.

THXSILK Classic Silk Bedding Set cross-shops across several editorial surfaces on this site: the full brand catalog, the price band it qualifies for and the in-depth guides for its category.
THXSILK Classic Silk Bedding Set - buyer FAQ
What comes in the THXSILK Classic Silk Bedding Set?
Four pieces: one silk duvet cover, one silk fitted sheet, and two silk pillow shams, plus a laundry bag the brand includes as a free gift. The duvet insert is not included and has to be bought separately. Per the brand's listing, the duvet cover closes with an invisible zipper and has 8 interior corner ties.
What does 25 momme mean on silk bedding?
Momme is the weight measure for silk fabric, so a higher number means a denser, heavier weave. THXSILK lists this set at 25 momme and 750 thread count. For reference, the Promeed silk we also list is sold in 22, 25, and 30 momme, so 25 sits in the middle of the range commonly offered for bedding.
How much does the THXSILK Classic Silk Bedding Set cost?
$899.99 for Full, $949.99 for Queen, $1,049.99 for King, and $1,229.99 for California King, verified against the brand's product data on August 2, 2026. All seven colorways are priced the same, and nothing was discounted off list on that date. No Twin size is sold, even though the published size chart lists Twin dimensions.
How do you wash silk bedding like this?
THXSILK's instructions are machine wash cold on a gentle cycle, inside out with the zipper closed, using a detergent made for silk. Air dry away from direct sunlight, do not tumble dry, and cool iron on the reverse side if needed.
THXSILK Classic Silk Bedding Set vs Promeed silk, which should I buy?
Promeed is the cheaper way into the material: single mulberry silk pillowcases at $55 to $104, and full silk sheet sets at $446 to $760 when we verified them in July 2026. The THXSILK four-piece set is the fuller purchase at $899.99 to $1,229.99. We have not compared the two sets piece for piece or by momme, so the honest framing is a price gap, not a quality verdict. If you have never slept on silk, start with a pillowcase.
