Don't let my 4-star review dissuade you, as I've had to reassess prior products that initially I thought were great but then failed me in the long term. These are definitely full and plush, you might want to avoid if you prefer slightly thinner support, especially if you are a side sleeper. But so far I find them comfortable and meeting all of my expectations.

These Made My Bed Game Stronger

Color: 01 - White, Size: Queen (2 Pillowcases)

These pillowcases impressed me right away. The material feels good in your hands and the stitching looks like it was done right. Soft enough to sleep on comfortably, but not that overly silky soft that gets hot. I’ve washed them several times already and they came out looking the same each time. No shrinkage and no issues with the fit. I sleep pretty still, and honestly I never even think about the pillowcases once I’m out. That tells me everything I need to know. Great value and something I’d buy again.
