  • Best Value Does the Job Best Value Does the Job
Size: 80" L x 12" W
Fills the gap without losing functionality of a split king adjustable unlike those ones that are incorporated into a fitted sheet. Not bulky or rigid like the ones with plastic forms. Easy no straps. Great value. This does the job. Lays flat, soft foam, stays in place, comfortable to lay on, has removable cover. Can wedge into the gap at times if your mattress slides apart but doesn’t lose shape and you can readjust. Recommend! ... show more

  • What we were looking for.
Size: 80" L x 12" W
I liked how well they fit on my twin xl/split king mattresses. They cover our 14 in thick mattress perfectly. They stay on and don't bunch up like many of the others we've tried. They are not ultra smooth / silky, but soft and cottony, which is what I was hoping for. They wash well. I'm pleased with them, especially for what we paid for them. ... show more

  • They don’t fit; they are awful
Size: 80" L x 12" W
These actually get ZERO stars. Absolutely worthless product. I didn’t have time to try them with our beds until just 2 days after the return window. They are absolutely worthless and actually create MORE of a problem than solving one.

The select a couple twelve inch extra wide split king gap filler delivers. It is soft and luxurious. It comes with a remove a book cover that you can wash. I put it on and it immediately started to bloom and filled in the cracks. No more bed ditch. I'm very pleased. I purchased the eighty inch for our twin XL, and it was the perfect choice!

  • Creates a “hump” Creates a “hump”
Size: 80" L x 12" W
I was apprehensive with the “extra wide” aspect of the gap filler that we would feel the bump and edge of the foam. Once under the mattress pad and sheets it definitely is noticeable - but we are average size n& dont generally slide that close to the center of the bed… but there is a noticeable low “hump”. Probably better than the feeling of the mattress seam and cording ... show more
