Product Features

    Soft to Medium

    A gentle and supportive sleeping surface that moulds to your body shape. Ideal for those who prefer to sleep on their side

    Natural Fillings

    Natural fillings such as wool, cotton, cashmere and silk help to regulate body temperature during summer and winter

    Pocket Springs

    Pocket springs are individual independent springs that contour to your bodyshape and minimise partner disturbance

    Hand Side Stitched Border

    A highly skilled process that sews outer rows of springs to the mattress border ensuring consistent support across the mattress

    Hand Tufted

    Especially important for extra deep mattresses, tufting ensures the fillings are held securely in place, thus increasing the life of the mattress

    Viscose Cover

    A premium fabric that is soft to the touch, breathable and renowned for its attractive silk-like lustre

    Double Sided Mattress

    Can be flipped and rotated. Sleeping on both sides will ensure wear and tear is evenly distributed

    In addition to a 5 year guarantee, this mattress has a further 5 years manufacturing warranty for complete peace of mind

    60 Night Comfort Guarantee

    If you don't love your new mattress, contact us to arrange an exchange. A Protect-A-Bed mattress protector must be purchased with your mattress.

    Turning Handles
    Reinforced handles are fitted to the border to assist with rotating single sided mattress, plus rotating and flipping over double sided mattresses

Product Description

Exclusively designed for Archers, the Alexander and Cole range are a cut above the rest with an innovative blend of pocket springs and mini tablet springs.

The Tranquillity 4800 is the starter mattress in the range and boasts as much as 14 times the number of springs found in a standard open coil interior.

It’s fully upholstered in a 100% Viscose fabric with a traditional hand tufted finish that’s designed to ensure the deep fillings are held securely in place.

With 8kg per square metre of natural wool, cotton, cashmere and silk (4 times the normal amount), you can be assured of a luxurious and enhanced feel.

The unique set up of the interior is made up of 1000 inner pocket springs, with 1900 mini tablet springs on the top and bottom for heightened comfort.

As well as offering comfort, the tablet springs provide a smooth surface for the deep fillings, helping to reduce any chance of upholstery settlement.

The springs are supplied by Agro, Europe’s biggest manufacturer of springs, so you can rest assured, you're sleeping on an interior that's tried and tested.

Reserved for top-end mattresses, side-stitching is a labour intensive and intricate technique that takes experienced craftsmen many years to master.

The process of side-stitching involves sewing the outer row of springs to the mattress border using a long upholstery needle and high tension twine.

This provides complete edge to edge support and prevents the border from bowing out over time. It also increases the sleeping surface by 20%.
