The Temperature Control and Comfort Secrets of ELIYA Duvet Inserts

The "temperature code" for hotel sleep lies in the duvet insert. Guests' needs for duvet inserts seem simple — warmth — but are actually complex: they need warmth without heaviness in winter, lightness and breathability in summer, and moderate warmth in spring and autumn. At the same time, issues like clumping and feather leakage must be avoided. ELIYA duvet inserts are more than just warmth tools; they are sleep companions that accurately meet needs, allowing guests of different seasons and physiques to find a comfortable sleep state.​

Overly thick duvet inserts press down on the body, making it difficult for guests to turn over and affecting deep sleep. Overly thin ones lack sufficient warmth, causing guests to catch cold at night. Poor-quality duvet inserts have clumpy filling, resulting in "uneven local warmth." ELIYA's high-end down duvet inserts use 90% white duck down, which undergoes strict selection and cleaning. The down clusters are large with high loft, distributing evenly after filling to provide warmth without heaviness. Guests barely feel any weight even when covered, especially suitable for high-end guests pursuing ultimate comfort. The mid-range fiber duvet inserts use antibacterial filling with silver ion antibacterial ingredients, achieving a 99% antibacterial rate to effectively prevent mold growth. They adapt to different seasons: thin models (100g/㎡ filling) for summer, medium-thick models (200g/㎡) for spring and autumn, and thickened models (300g/㎡) for winter. They don't clump after washing and maintain long-term loft.​

In craftsmanship, ELIYA duvet inserts adopt square quilting with a quilting spacing controlled at 15cm×15cm. This prevents filling from shifting without reducing loft due to overly dense quilting. The edges are reinforced with overlocking, using 3cm wide cotton tape to withstand repeated arrangement — even when housekeepers pull the duvet insert while making the bed, the edges won't tear. In winter, thickened down models are selected; their high loft traps more air, providing 40% better warmth than ordinary fiber duvets. In summer, thin fiber models are chosen, with breathable non-woven inner covers to keep guests from feeling stuffy in air-conditioned rooms. Moderate thickness options are available for spring and autumn, balancing warmth and breathability.​
