Pillows
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
Pretty decent for the price. Along with its conventional use, those pillows are pretty comfy to sit on. Pillows are for more than just sleeping; they’re excellent seat cushions!

Lumpy!

These are horribly lumpy! The filling clumps. They won’t lay flat.
This is after working with them to try to ref, fluff them
Terrible product

A true medium firm pillow
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
I like a medium pillow that lets my head sink in a little bit so my neck isn't cranked at an angle but not to the point where it sinks in completely. You can also scrunch it a little bit. Also love that it's queen size, as most queen sheet sets for come with queen pillow cases, not standard. I am surprised it worked out, very happy with it.
