We used it straight away and it was perfect, light but still a bit of fluff. We have a king size bed but always use a super king size duvet. The benefit of this is if you share a bed, there are plenty of covers for both of you. We ordered a super king for this duvet and as a general rule to help people put the duvet on properly, the lines go horizontal/across to your bed. If you do it the other way, it's just very long and won't fit your duvet cover! I've attached pictures of the duvet without our cover on so you can see how much it overhangs but remember it is a size bigger than the bed. We also haven't washed it but I've had no issues washing this brand of duvet before. ### ⭐⭐⭐⭐⭐ Lovely duvet *by M***R on 6 February 2024* Lovely duvet - just right weight - neither too cool nor too hot. ### ⭐⭐⭐⭐ It's nice , light and soft *by H***H on 15 May 2023* Very light bought for summer but we find it incredibly warm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/128910221-silentnight-cooler-summer-deluxe-with-dupont-4-5-tog-duvet](https://www.desertcart.jp/products/128910221-silentnight-cooler-summer-deluxe-with-dupont-4-5-tog-duvet) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-04*
