These king size pillows put the king in the term king size. They are support dense and provide good back support while sitting up and reading. They fill every inch of a king size sham. The down side (no pun intended) is that due to the thickness, the pillows are too high for use as an actual pillow under your head! So be prepared to add "normal" pillows for that use.
I purchased these pillows because the description said it was medium firmness and good for side sleepers, upper back pblms etc..... And they're not! They are WAY too firm and hurt your neck. I'm hoping they flatten out just a bit with time like all pillows do. To sit propped up and watch tv these pillows work, but not to sleep with. Your neck stays way to propped up.
These pillows are extra fluffy and perfect for pillow shams. Initially looking for pillows to replace the ones we sleep on but later realize I can rotate the ones in the shame with the newer ones. It worked out great! They really keep their shape.
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.
