Euro-top and pillow-top are 2 terms used interchangeably, but they do have slight differences. The biggest difference is in the way they are stitched.
A euro-top mattress is stitched flat and even with the side of the mattress. A pillow-top mattress is stitched a little bit under the pillow-top giving it that look of a pillow on top of the mattress.
Other than that, the differences are minimal. Once you put your sheets on you may never see a difference. Both euro-top and pillow-top mattress can come in various firmness levels from plush to extra firm. Its mostly esthetic so do not overthink it too much! You should not be set on one over the other.
