Sizing

Split King vs Split-Top King

A Split King separates the sleep surfaces along the full mattress length. A split-top design keeps the lower portion joined while allowing the upper sections to move more independently.

The important distinction

The split-top approach can preserve more of a shared mattress feel while supporting independent upper-body articulation on compatible bases.

What to check when shopping

Compatibility is the key constraint: mattress and base design must match the intended split format, so confirm the exact product pairing before purchase.

Practical tip: Compare the exact product configuration and current terms rather than assuming a category-level feature works the same way on every mattress.
