I did not purchase these to use as normal pillows to sleep on, first and foremost. I bought these to use more like accent pillows, against my headboard. These pillows were so soft and saggy they didn't even stand up on their own, but slumped over. Ugh, if you want anything resembling a normal pillow, I'd buy something different.
These work well for extra bed pillows in my decorative shams. They are a little limp but I think look just fine. If you want really full euro shams then you probably would be disappointed with these. For me, they work fine and are good to sleep on too.
Since Square pillows are generally used as decorator pillows, I was quite surprised that they had NO body! They barely stand up! I haven't put my head on them...but I may actually like them for that purpose (although, they may even be too squishy and flat for that too!). But who uses square pillows under their head? The only reason I didn't return them is the hassle factor, and that I bought them for my guest bed - so I don't have to fiddle with them that often. Note, the quality was fine other than that.
