- Multiple Uses: Perfect for use on patio furniture, garden chairs, sofas, beds, and more. Could also be placed inside your favorite pillowcases to decorate your patio or any indoor and outdoor space
- Notes: Pillow inserts are vacuum-packed for shipping and may not look fluffy right away. Please press and squeeze to restore their full, fluffy shape. Do not machine wash—hand wash only
- Pay Attention: Please keep the pillow core in a dry state. When using a pillowcase outside the pillow core, if the pillowcase encounters water, sweat droplets, oil droplets, or other liquids, please take out the pillow core in a timely manner and wipe it dry or natural air drying to prevent the liquid on the pillowcase from penetrating and coming into contact with the pillow core. The enclosed space between the pillowcase and the pillow core can cause damage to some extent due to the moisture caused by the qualitative change of the liquid

### ⭐⭐⭐⭐⭐ Well made

Very well made . I loved them they keep their shape . Not cheap notty fiber

### ⭐⭐⭐⭐⭐ They are comfortable. They do expand
*by B***S on March 8, 2026*

Shocked they really do expand! Great pillows!

### ⭐⭐⭐⭐⭐ Good Value for the Money
*by T***R on February 15, 2026*

These are great additions for our outdoor couches. They are not firm at all. They actually deflate when you lean against them which is the only downside. They poof right back up when you get up. We got a size above what the cover size was. Covers were 24” and we bought inserts that are 26”. I like that there is a zipper allowing you to access the inside. The material is plasticity so it will keep moisture out. I will say these are a good value for the money. I will fill in with smaller decorative pillows for extra lumbar support.
