Encapsulated

An encapsulated mattress has a reinforced foam border that runs around its entire perimeter, creating excellent edge support while maximising your usable sleep surface. Encapsulation prevents the sides from collapsing when you sit or lie near the edge, effectively extending the supportive area right to the border of your mattress. The foam frame works harmoniously with the internal springs to maintain consistent support across the entire surface.

Different Types Of Encapsulation

Encapsulation can be found on any mattress— open coil, pocket spring, hybrid, and pure foam models. However, manufacturers use different encapsulation materials that suit different firmness ratings.  

Some mattresses have a single piece of high-density foam that creates a solid frame, while others layer different foam densities for graduated support.

Premium models might combine reinforced springs with foam encapsulation, creating a dual support system that maximises stability while preventing sagging.

How An Encapsulated Mattress Feels

The most noticeable benefit appears when you sit or lie near the edge - there's no sensation of rolling off or sinking. The sturdy perimeter maintains its shape, giving you confidence to use the full width of your mattress.

Enhanced edge support will prove particularly valuable if you share a bed or need additional stability when getting in and out.

The expanded sleep surface also means you can use the entire mattress without gravitating toward the centre, effectively increasing your usable space by up to 20% compared to non-encapsulated designs.

The Best Encapsulated Mattresses

Our collection showcases outstanding encapsulated designs for every preference.
