It is heavier than others I've purchased and very "choppable". These are made in the United States and have no odor when you open them up. They are worth the higher price tag. ### ⭐⭐⭐⭐⭐ Nice quality! *by S***I on April 3, 2025* Purchased for European shams for guest bedroom and they are nice and full and comfortable. ### ⭐⭐⭐⭐⭐ Fluffy, dense, nicely weighted *by J***R on March 28, 2025* It’s so nice to find an exceptional product that’s also from the USA. Their sizing guide is spot on and their pillows are amazing. They’re fluffy, dense, and nicely weighted. I replaced down pillows from ikea with feathers constantly poking out and I should’ve done it sooner. ## Frequently Bought Together - Pillowflex Synthetic Down Pillow Insert - 16x18 Down Alternative Pillow, Ultra Soft, Large Rectangle Body Sleeping Pillow, Lumbar, Long, Back - 1 Decorative Pillow Form - puredown® Lumbar Pillow Inserts 12 x 20 (Pack of 2, White), Filled with Feather and Down, Decorative Pillows for Couch, Home Decor - basic home 12x20 Decorative Throw Pillow Inserts-Down Feather Pillow Inserts-Oblong-Cotton Fabric-Set of 2-White. --- ## 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.co.th/products/723515955-synthetic-down-pillow-insert-16x18-down-alternative-pillow-ultra-soft](https://www.desertcart.co.th/products/723515955-synthetic-down-pillow-insert-16x18-down-alternative-pillow-ultra-soft) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
