Product Description

This mattress specification has been discontinued.

The Rest Assured Boxgrove 1400 is a hand-made mattress new to the Rest Assured range. This beautiful mattress is designed to offer a slightly firmer than Medium feel, without compromising on the comfort it offers. This deep and luxurious mattress is great value for money and is designed to stand the test of time.

The 1400 Pocket Springs act independently to support the body perfectly and instantly. Each spring moves to act like a piston, moving up and down as pressure is applied. The result of this specification is support that moves in harmony with the body's contours, preventing painful pressure points from developing and ensuring a great night's sleep, night after night.

The Boxgrove 1400 is topped with a deep layer of hand-applied natural fillings, enveloping the body with a sumptuous and luxurious cushion feel. This surface layer is a deep pad of luxury fillings, including pure Wool and Silk. Both totally breathable and comfortable.

The surface layers of this mattress are bound in place by the hand tufting process. This technique sees the mattress' firmness refined to a very precise level and this feature also increases the durability of the mattress.

The Boxgrove 1400 is complete with air vents and handles for easy movement. This is a no-turn mattress, which will only require rotation to maintain. we recommend a seasonal rotation.

Delivery is completely free! We deliver to your room of choice with our two-man team free of charge to mainland UK.

    Perfect for me, great value and very well made.
    Quite firm I think though, which may not be for everyone.

  • Pocket Sprung

    Pocket Sprung units are an adaption of the traditional open coil/continuous spring unit. By placing each spring in its own individual 'pocket' (a fabric sock-like pouch), the spring is not joined to any other part of the mattress. The pocket that supports the spring is then joined to its neighbouring pockets and this effect creates a unique feel.

    By creating a spring unit in this way, it allows the springs to move independently, rather than sharing the pressure with surrounding springs. This effect allows for much more accurate contour following and a more comfortable feel overall.

    If you were to push your hand into a traditionally sprung mattress, the area around your hand would dip/sink too. With Pocket Springs, this sunken area is much more remote and therefore more accurately follows the contours of the pressure source. There are differences in the techniques used to create Pocket Springs, but more or less they remain the same.

  • Tufted

    Tufting is a traditional and highly successful way of finishing a mattress surface. The end result makes the mattress appear to have dimples, or buttons dipping into the surface. This technique is designed to hold the surface materials together and to fix them to the core of the mattress to prevent the layers moving over time. A modern method is Spiral Tufting, which involves fixing the surface to the fillings and spring unit.

    The actual tuft is usually made from a cotton felt material and is fastened by a cotton or wool chord to the spring unit, in most cases. A tufted mattress will normally have a firmer surface than a non-tufted/quilted surface. The reason for this is that the Tufting process actually holds the surface material and underlying fibre layers tightly together. This will create a tighter, firmer feel than a quilted mattress.
