Good pillow, not the best overall but it's good value for what you pay.
Size: 20 in x 54 in, Style: 1 Pack
Can be slightly uncomfortable at first, but it goes away quickly, very soft and doesn't hold shape very well, but pillowcases fit well on it, it's pretty quality, and it's durable. There's not much more you can ask for in a pillow.

Love being able to change with the seasons!
Size: 20 x 20 inches, Style: 4 Pack
I’ve been using the Amazon Basics Square Hypoallergenic Pillow Inserts with my seasonal pillow covers, and I absolutely love them. I like to switch out my covers each month or holiday, and these inserts make it so easy to keep my living room looking fresh and festive year-round.
They hold their shape really well and give my pillows a full, plush look without feeling too stiff. I also appreciate that they’re hypoallergenic, which is a big plus for my home.
Overall, these inserts are a great staple to have if you enjoy decorating with interchangeable covers. They’re comfortable, reliable, and perfect for keeping up with seasonal décor changes. Highly recommend!
