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.

View full detailsDifferent 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.
The Dura Beds Cloud Lite Tranquillity 1000 combines 1,000 pocket springs with Cloud Lite® Foam technology, creating a medium-comfort surface that's remarkably light yet durable.
At 27cm deep, this mattress offers exceptional edge support while maintaining cooler sleep temperatures than traditional memory foam.
The Kayflex Hibern8 features 1,200 pocket springs and gel-infused latex for superior temperature regulation.
Its foam encapsulation delivers impressive edge-to-edge stability, while the removable zipped cover adds practical convenience to luxury comfort. The medium-to-firm feel suits those seeking substantial support without compromising on comfort.
The Kayflex O-Zone 4000 boasts 4,000 pocket springs and a dual-season pillow top for ultimate luxury. The O-Zone technology creates remarkable edge support, while the flippable topper offers temperature options for year-round comfort.
The Airtex border enhances breathability, making this soft-to-medium mattress perfect for those who value versatility and premium features.
Each mattress includes free UK delivery and perfectly balances innovation and practicality. Our encapsulated range offers superior stability and comfort whether you prioritise temperature regulation, edge support, or versatility.
