r/sleepnumber on Reddit: Flannel split-top sheets?
August 28, 2025 -

I searched this sub but got no results, so I figured I’d ask. Has anyone found flannel sheets for the split-top bed? We’re looking for some warm sheets for this winter and found a set of fleece ones, but we’d prefer flannel. TIA!

Very few manufacturers make this kind of mattress. So it makes sense. There are fewer options for the split sheets.

Jersey sheets If you like the feel ... jersey sheets. These are made from knit cotton rather than woven, which gives them a flexible, slightly stretchy texture. Jersey is naturally breathable and soft, and while it’s lighter than flannel, it still provides comfortable warmth that works well year-round—especially for those who like bedding that moves with them.

We got a split top/flex head adjustable king bed last year and LOVE it, but I’m very limited in sheet selections. I miss flannel sheets! Does anyone know of a good place to get sheets that fit this type of bed? Bonus for flannel sheets.

I really don't wanna buy the sheets from sleep number since I believe the prices are over inflated. Are there alternatives that I could get that aren't just basic quality? Someone recommended Sheex but they don't do a flextop. Thank you

In the past four years, we've experienced issues with two fitted sheets that ripped, despite proper care. Additionally, two grey sets developed white spots that resemble bleach stains. Our housekeeper changed the sheets either weekly or every other week. On one side, we have used three air mattresses, but the third one doesn’t hold air. The other side has its second mattress, which has developed a leak. The foam has been split since before COVID, around a year ago. Right before the lockdown, the board in the pump box failed; fortunately, the replacement part and repair were covered at no charge. Overall, the quality has been poor. However, customer service and the local technicians have been helpful in ensuring the system works by replacing items with more affordable options.

I am a Store Manager working with Sleep Number. If you need a cheap set of sheets you can find some head-split sheets on Amazon. You can also use regular king sheets from anywhere but just be mindful of using the head elevation as this does stretch any set of sheets. Our sheet sets are a bigger price because they are made with long-staple fibers (this reduces piling), have wider elastic bands (prevents the sheets from needing tucked back under the mattress when using the adjustable base), our sheets are made of a higher quality material (compare cotton, polyester, supima cotton, rayon, lyocell, wool, spandex, nylon, and other fibers), and finally we have a strap that fits every corner of the mattress to prevent the sheets from popping off. Yes, these sheets cost more. You can also get $190 from doing your activities on the Sleep Number App and combine those rewards with sales to get a set of free or very discounted sheets.
