Comparison with other goose down comforters

Q1: What makes goose down comforters different?

What makes goose down comforters different?

Have you ever had a light, deep sleep? Down (feathers) is the warmest natural material to date.

It is lightweight yet retains warm heat due to its good recovery ability.
*Source: The World of Feathers

• Warmth: A lightweight, warm natural material that maintains body temperature even in cold water or weather.
• Freshness: Quick drying with moisture-wicking properties, keeping you comfortable without stickiness while sleeping.
• Comfort: The instant recovery (loft) of goose down softly wraps and cushions the body with movement.

Q2: Could the quality of goose down be low?

Premium level fill power and weight of goose down

Experience the comforter you felt in 5-star hotels.

Fill Power

Fill power is a core factor for goose down comforters. Higher fill power means better insulation and warmth.

Down Cluster

The down cluster content determines fill power and warmth. Higher content means lightweight warmth that gently wraps the body.

Filling Weight

Balanced filling weight is important—not too heavy or too light—for harmonious warmth.

Q3: Isn't the most expensive necessarily the best?

Point 1: Feel-good stitching like in hotels

Point 2: Plush and warmer Polish goose down

Point 3: Proprietary stitching structure to maintain warmth long

Baffle box construction: Modules with ‘walls’ between fabric pieces to prevent down from shifting and maintain fluffiness and warmth.

Point 4: Durable 80s thread count cotton cover

The Signature Line cover is 80s thread count plain weave cotton—durable, breathable, and minimizing fiber loss for long use.

Point 5: Unique Zero O'clock details

Detail 01: Carefully designed point labels

Zero O'clock tips for managing your goose down comforter

During delivery, the comforter may be temporarily compressed. After unwrapping, dry it well in a ventilated place.

Down regains loft naturally, but complete recovery may take 2-3 days.

Care instructions to maintain quality:

• Air or dry in a well-ventilated place 1-2 times monthly.
• Use comforter covers to protect and secure sides.
• Wash gently by hand or machine separately and follow detergent instructions.
• Dry thoroughly to prevent mold and odor.
• Avoid excessive heat or direct sunlight; air occasionally for freshness.
• Store in provided bag with desiccant; avoid heavy compression.

How to select the comforter right for you

Zero O'clock Signature Line offers various weights to suit your rest environment.

Zero O'clock Comforter Selection Tip

1. Size Selection | Select from S/SS, Q, or K sizes. For single users wanting roomy comfort, Q size is recommended. For couples or cold sleepers, consider size and weight accordingly.
2. Weight Selection | Choose basic or heavy weight based on climate and heating. Heavy recommended for colder environments; basic works well with electric heating.

Q&A

Q: Why are there black spots inside the comforter?

A: White goose down may contain some brown or black feathers, which is natural and part of quality down. It doesn’t affect quality.

Q: Does mixing goose down in different chambers reduce quality?

A: Goose down is divided into 36 chambers with double stitching to secure fill; seams prevent down shifting, maintaining quality.

Q: Will the comforter have any odor?

A: Tested with 8 rounds of washing; no odor was detected. Washing without chemicals preserves freshness; some smell may occur but dissipates within 1-2 hours of airing.
