What is a Foam Encapsulated Mattress?

Foam encapsulated mattresses work by encasing the inner mattress fillings within a supportive foam border. Essentially, foam encapsulation is a "box" of support foam that reinforces the whole mattress. This outer foam border helps to improve mattress durability, reduces the likelihood of sagging and prevents a feeling of "roll-off".

In summary, foam encased mattresses include the following key features:

  1. A supportive foam layer on the base of the mattress
  2. A foam border built around the sides of the mattress to create an open box
  3. Comfort and support fillings

Additionally, foam encapsulated mattresses may also feature a layer of support foam above the springs. This acts like a "lid" and ensures the mattress surface is well supported.

A comfort layer made from memory foam, latex or gel foam - and a cover - completes the mattress. Whilst it's possible to find foam encapsulation within a wide range of mattresses, our foam encapsulated mattresses usually contain memory foam and pocket springs.

What are the benefits of foam encapsulation?

If you're looking for a sturdy, supportive mattress, a foam encapsulated mattress is a good choice. Read on to discover the benefits of extra mattress support.

What foam is used in a foam encapsulated mattress?

A foam encapsulated mattress is typically made from reflex foam. A type of polyurethane foam, this support foam is branded as 'Reflex' by British Vita. This high-density foam surrounds the mattress springs for enhanced support and firmness. Additionally, reflex foam features incredible bounce-back properties, which helps to reduce the risk of sagging and helps maintain the shape over time.

What's inside a foam encapsulated mattress?

As with all mattresses, there is a great variety of foam encapsulated mattresses. "Foam encapsulated" simply refers to the high-density foam support border; many encapsulated mattresses feature pocket springs or open coil springs (also known as standard springs) and an additional comfort layer.

This comfort layer is most commonly found on top of the foam "box". There are many different comfort fillings available, and each will affect the overall feel, comfort and support of your mattress in different ways.

  • Superflex foam

Superflex foam offers a slightly softer, more sumptuous feel for luxury comfort and gentle support.

  • Memory foam

Our most popular type of foam, memory foam offers responsive comfort and adapts to your movements as you sleep.

  • High-density foam

Also known as reflex foam, high-density foam offers a more supportive sleeping surface.

Do I need to turn my foam encapsulated mattress?

No, you don't need to turn your foam encapsulated mattress. Easy to care for and maintain, foam encapsulated mattresses are single-sided due to the reflex foam base and encasement. You only need to rotate your encapsulated mattress from end-to-end - we recommend doing this once every three months. It's a great option if you find it difficult to turn your mattress or would simply prefer the convenience of a single-sided mattress.
