Utopia Bedding Throw Pillow Inserts (line)
A plain, washable, multi-pack polyester insert in standard square sizes is the foundation of a pillow setup, because you can then swap covers by season without rebuying the whole pillow.
Not for: People who want the soft, slouchy 'chopped' look and slow recovery that only feather or down inserts give.

IKEA FJÄDRAR (line)
Feather fill gives decorative covers a plush, shapeable look, and the insert can be fluffed to restore its loft.
Not for: Anyone avoiding animal-derived fillings or wanting a finished pillow with a decorative cover.
Which one fits you
fuller loft, odd sizes
Foamily Premium Hypoallergenic Stuffer Pillow Insert (line)
It is sold individually in many square and lumbar sizes, so it is easy to match an unusual cover.
Not for: Buyers furnishing a whole sofa who would save with a multi-pack.
swappable velvet covers
MIULEE Velvet Throw Pillow Covers (line)
These are inexpensive-looking-rich velvet covers in many colors and sizes, with hidden zippers, sold in pairs.
Not for: Homes with pets that shed heavily, because velvet holds hair.
outdoor or sunroom
Sunbrella (brand)
Solution-dyed acrylic fabric resists fading and mildew far better than printed polyester outdoor pillows.
Not for: Shoppers who want plush velvet or linen textures indoors.
