I think these pillows are a good value, but my husband is highly selective about which pillows are comfortable for him, therefore, I went out on a limb and ordered these, hoping they would work, but they were "too filled" for him. He wants to be able to move the pillow around and have his head "sink in" in order to be comfortable. They would have been fine for me, but he wasn't happy, so I had to return them. I still do think they would work for plenty of people. There was no smell. I don't know how they would hold up over time as we left them in their covering and simply tried them for a bit before he made his judgment.
These are nice big fluffy pillows. I needed new ones for my guest bedroom and one guest said it was perfect, not too soft and not too hard but my other guest said it was too soft and added that they liked a very firm pillow. They seem just right to me. Fabric is good on the pillow and they arrived faster than I had expected. I would buy these again.
