Overview
Zinus makes the Jayanna as a bifold box spring on a steel frame with a poly jacquard cover. It folds for carrying through tight halls and takes shape when unfolded, with no assembly required.
The reason to choose it is easy handling and a low height that stops a thick mattress from towering. The limit is a firm, tight top built for support, not a plush surface.
Who it's for
Movers, renters and anyone fitting a split king mattress up narrow stairs get the most from the folding design. Owners of a single king mattress or a platform bed with slats should confirm size and compatibility first.
Pros and cons
- Folds for carrying
- No assembly required
- Low profile height
- Spot clean only cover
- Firm tight top only
- Heavy for one person
Performance notes
Two steel frames hinge in the middle, so the unit folds for transport and locks flat when opened. The tight top and steel structure spread a mattress's weight across the frame.
