I think the seven-degree space is better, because this brand is simple, generous and famous, and it will be more comfortable. Sophie's workmanship is a little rough, but Sophie's is cheap. I have been using the seven-dimensional space. I always think that the seven-dimensional space will make people feel young and well packaged. Sophie is a little boring, of moderate thickness and fine workmanship. Sophie has always had air in it, which is loose and soft, which is not good-looking.
