Really comfortable
Model: Soft-2PK, Size: Queen
I had been looking for new pillows and my daughter had recommended the Bedsure pillows as being so comfortable and soft. I bought a 2 pack queen that were on sale on Amazon and absolutely love them they are soft fluffy and have not flattened or lost shape at all. I am really happy with purchase. Great pillows great price.

Fluffed to perfection.
Model: Soft-2PK, Size: Queen
I was a tad disappointed when I first opened the vacuum sealed packaging. They were flat and thin and disappointing. Once I fluffed them (took about 15 minutes per pillow) they were suddenly AMAZING. Fluffy and soft and perfectly supportive.

Ok
Model: Soft-2PK, Size: Queen
These pillows are ok. I would not purchase them again as they go flat, but they will fluff up again once you fluff them.
