Features

• 𝟱𝟬𝟬 𝗚𝗦𝗠 𝗪𝗶𝗻𝘁𝗲𝗿 𝗪𝗮𝗿𝗺𝘁𝗵 𝗦𝗲𝗮𝘀𝗼𝗻 𝗗𝘂𝘃𝗲𝘁 𝗜𝗻𝘀𝗲𝗿𝘁 - You receive two complete duvet inserts in one box: a 150 GSM summer insert and a 350 GSM all-season insert. Use them separately for spring through autumn, or snap them together via the built-in 8-button system for a 500 GSM winter duvet. Three warmth settings. No second purchase. No storage hassle - when you switch, the lighter insert stores flat inside the heavier one. This snap system is unique to Delara and unlike anything else in the down alternative category. Available in Twin (68"×86"), Queen (88"×92"), and King (108"×92"). Double-needle seams and grey handmade piping on the perimeter.
• 𝗗𝗼𝘄𝗻-𝗟𝗶𝗸𝗲 𝗦𝗼𝗳𝘁𝗻𝗲𝘀𝘀 𝗪𝗶𝘁𝗵𝗼𝘂𝘁 𝘁𝗵𝗲 𝗔𝗹𝗹𝗲𝗿𝗴𝗲𝗻𝘀, 𝗙𝗲𝗮𝘁𝗵𝗲𝗿𝘀, 𝗼𝗿 𝗔𝗻𝗶𝗺𝗮𝗹 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝘀 - Both inserts are filled with sterilized hypoallergenic polyester microfiber - engineered to mimic the light, fluffy drape of goose down without feather dander, quills, or animal allergy triggers. The 150 GSM summer insert sits light as a layer of air. The 350 GSM provides the plush, enveloping warmth of a mid-weight down duvet. Fully vegan - zero animal products in either insert. The complete product carries OEKO-TEX Standard 100 certification, testing every component against 100+ harmful substances.
• 𝗚𝗢𝗧𝗦 𝗖𝗲𝗿𝘁𝗶𝗳𝗶𝗲𝗱 𝗢𝗿𝗴𝗮𝗻𝗶𝗰 𝗖𝗼𝘁𝘁𝗼𝗻 𝗦𝗵𝗲𝗹𝗹 - Both inserts are encased in a GOTS certified long-staple organic cotton shell in a 300-thread-count sateen weave - the smooth, noiseless surface your skin contacts every night. GOTS certification covers the cotton shell fabric: grown organically, processed without harmful chemicals, verified from farm to finished fabric. The fill is hypoallergenic polyester microfiber, certified under OEKO-TEX Standard 100 for the complete finished product. No synthetic shell, no polyester touching your skin - the organic cotton layer is between you and the fill at every point.
• 𝗕𝗮𝗳𝗳𝗹𝗲 𝗕𝗼𝘅 𝗖𝗼𝗻𝘀𝘁𝗿𝘂𝗰𝘁𝗶𝗼𝗻 + 𝟴 𝗦𝗻𝗮𝗽 𝗕𝘂𝘁𝘁𝗼𝗻𝘀 - Baffle-box sewn chambers keep the microfiber fill evenly distributed across every inch of both inserts - no thick patches, no cold corners, no migration overnight. The same 8 built-in snap buttons that connect the two inserts for winter also function as tie tabs to anchor either insert inside any duvet cover. Eight contact points versus a standard four - the insert stays in place even when you move during the night.
• 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗪𝗮𝘀𝗵𝗮𝗯𝗹𝗲 - Both inserts are machine washable on a gentle cycle with cool water in a large front-loading machine - wash them together or separately. Tumble dry on low heat with 2–3 dryer balls, stopping every 20 minutes to shake and redistribute the microfiber fill. This step is essential - without dryer balls, microfiber fill clumps permanently. Before first use: shake both inserts vigorously and tumble dry on low for 15–20 minutes to restore the fill's loft after packaging compression. A light synthetic scent on first opening is normal; air in a ventilated room for 24–48 hours before first use. The 150 GSM insert stores flat inside the 350 GSM when not in use.
• Machine Washable: The bed comforter set is easy to care which can save you more time and energy. For year round softness and prevent pilling up, it's highly recommend to wash it in the gentle cycle with cold water, sun-dry or tumble dry in low when needed.
