Lullabuy is a brand operated by Lullabuy Commercial and Trading Inc., a Burnaby company that sells bedding online to Canada and the United States. For this duvet the product page publishes two material facts: Fabric: 100% Cotton, and Filled: 100% Mulberry Silk. Silk grade, silk origin and whether the fill is long strand or short fibre are not published. Neither is a country of manufacture.
It comes in White, in Twin, Double/Queen and King, with weight options of 2.0KG, 3.0KG, 4.0KG and 5.0KG. Twin stops at 4.0KG, which makes 11 variants. Lullabuy does not say whether the KG figure is the silk alone or the finished duvet, and it gives no warmth or season guidance for any weight. The SKU codes read 150x200cm for Twin, 200x230cm for Double/Queen and 220x240cm for King. Thread count, weave and corner loops or ties are not mentioned.
Care is brief. The page says the duvet typically does not require cleaning during normal use when it sits inside a cover, and recommends gentle hand wiping if it becomes stained. No textile certification and no test report is published for it.
The gallery photos disagree with each other. The first shows a quilt printed with the word Butterfly, with a SILK QUILT corner label and no Lullabuy mark. The other three show a shell with a woven check or stripe texture. The listing gives a single fabric line and does not say which shell ships.
The shipping policy offers free standard shipping on all orders to the contiguous United States and Canada with no minimum, while the product page words it as eligible orders. Alaska, Hawaii, US territories and APO/FPO/DPO addresses are outside the delivery area. The policy gives 1 to 2 business days of processing inside a 3 to 10 business day total.
The return window is 30 days from delivery. The duvet has to come back unused and in its original condition, Lullabuy pays return postage for US and Canadian orders, and there is no restocking fee. Items that cannot be returned for hygiene reasons once opened are excluded where the law permits, and the brand does not say whether an opened duvet counts. That makes it a return window, not a sleep trial.
Lullabuy publishes no warranty. Its Terms of Service disclaim implied warranties to the maximum extent the law permits, and for damaged, defective or incorrect items the return policy promises a review and a remedy that may be a replacement, exchange or refund. Support is by email at contact@lullabuybed.com, and no phone number is published. The policies list hours of 9:00 AM to 6:00 PM Eastern, Monday to Friday, while the contact page also lists Saturday and Sunday.

Lullabuy Pure Natural Mulberry Silk Duvet - buyer FAQ
How much does the Lullabuy mulberry silk duvet cost?
On Lullabuy's US store on September 30, 2026, prices ran from $175 for a Twin at 2.0KG to $455 for a King at 5.0KG. The Double/Queen spans $179 at its lightest weight to $449 at its heaviest. No variant carried a struck price. Standard shipping is free to the contiguous US, and cart and checkout were not opened.
What size is the Lullabuy silk duvet in inches?
The Size Guide on the product page lists Twin at 59 x 79 inches (150 x 200 cm), Double and Queen at 79 x 91 inches (200 x 230 cm) and King at 87 x 94 inches (220 x 240 cm). The cm figures match the SKU codes. Check your duvet cover against those numbers before ordering, since a return inside the 30 day window needs the duvet unused.
What does the 2.0KG to 5.0KG weight mean on the Lullabuy duvet?
Those are the weight options on sale: 2.0KG, 3.0KG and 4.0KG in every size, with 5.0KG added for Double/Queen and King. Nothing on the store explains if that number covers the silk fill or the finished piece, and no weight comes with a warmth rating or season guidance. On a Twin, price climbs from $175 at 2.0KG to $359 at 4.0KG.
Can you machine wash the Lullabuy mulberry silk duvet?
The product page says it typically needs no cleaning in normal use inside a cover, and suggests gentle hand wiping for a stain. The store FAQ sends buyers to each product page or care label. The return policy excludes washed items, so washing it closes the 30 day return option.
Does the Lullabuy silk duvet have a warranty, and how do returns work?
No warranty term appears anywhere on the store, and its warranty page returns a 404. Returns run 30 days from delivery for an unused duvet free of stains and odors, with original packaging where applicable. For US and Canadian customers Lullabuy covers return postage and charges no restocking fee. Refunds generally follow within 5 business days after inspection.
