I like these pillows a lot. They are definitely outdoor material and would be kind of weird inside. I docked 1 star because I think they're just a little overpriced, but I liked the pattern so I went for it.
Note: If you're inexperienced at ordering pillows, be careful not to order them too small!
2021 Update: I have been using these pillows outside, and they have faded A LOT in two years. I have some other outdoor pillows that are even older and are still as bright as ever. -1 star because longevity is important to me.
