Care & Usage

Every effort was taken whilst building your new mattress to ensure that it will provide you with excellent comfort and support for years to come. However, there are a number of steps you can take, during use, to make certain you get the most from your new purchase

We highly recommend using an under blanket or good quality cotton or wool-faced mattress protector.

Avoid using plastic sheets as beds need to breathe and using plastic will lead to damage through condensation.

It’s a good idea to air the mattress regularly too, by leaving the bed linen folded back for a few hours each day.

Remove dust and fluff from your mattress every few months using a soft brush. Never use a vacuum cleaner as this can displace the natural fillings.

Any spillages should be absorbed using a dry cloth or paper towels. If you need to sponge the mattress, use a damp cloth and a very mild solution of soap and water.

As most people sleep in the same position every night, body impressions are a normal feature of handmade mattresses.

You may find fillings settle or dip in the area where you sleep which can leave a ridge in the centre of the mattress.
