I have to tell you, I was excited for fun Betsy Johnson sheets for my split king...until they pulled up literally every time I sat on my bed. After a bunch of research, I found that ghost bed has patented a special elastic to hold the sheets in place. They have not come off even once. Not even after some extra curricular activities!
I recently made a purchase of GhostBed sheets along with 2 other brands, so I could rotate my sheets weekly. The GhostBed sheets were the first of four different sheets that I purchased and arrived, and I slept on them the first week. I was amazed because I do sometimes wake up in the middle of the night hot. I was pleasantly surprised by the cooling effect of the GhostBed sheets. It was absolutely amazing how I felt. The second and third week were with other brand sheets, and one of the two that I slept on felt comfortable during the night, but still didn't meet the quality of the GhostBed sheets. I have to say that I can't wait to get back in the rotation of the GhostBed sheets which were hands down the best sheets I have ever slept on. I will be sending at least one of the other brands back and getting another GhostBed sheets. I'm so glad they make sheets for split king, I only wished they came in more colors, but at least they perform AAA+. Sheets are definitely a personal preference and I didn't want to get hung up on thread count and promises of this or that, but whatever GhostBed does with there sheets....keep doing it!!
These sheets are like satin and are easier to clean. They never pull up because of the oversized elastic band. I live in the north where we have all four seasons. They are cool in the summer and warm in the winter. Best sheets ever.
