Hi Sarah,

Many thanks for your question on our Origins Pocket 1500 Mattress. It's one of our best sellers.

The Natural Fibre is 300GSM of Wool in the final top comfort layer. We list all the contents of our mattresses on each product listing. Below is a cutaway and the exact components of this mattress.

Why do we list the grams per square meter of mattress upholstery?

We are one of the very few mattress retailers that will happily disclose down to the gram what's inside our hand made mattresses. This is because it's only with this information that you can accurately compare mattresses and see their suitability depending on your needs.

If you can't see what's inside a mattress you really are just guessing. We don't like having to guess and don't think our customers should either.

By fully understanding the layout and composition of your mattress you can work out how suitable it's going to be. You can also assess its value compared to other models by comparing the number of fillings. Below is a handy table explaining how various mattress fillings will feel (obviously if they are layered up then the overall feel and properties does change somewhat).

Knowing the Spring Unit of a Mattress

It's not just mattress comfort layers that you need to fully understand but the pocket spring unit that's inside any mattresses you're considering buying. You need to know the gauge of the wire and the weight limit to know if it is suitable for your body weight.

The Origins Pocket 1500 mattress uses a 1.4 gauge spunbond pocket spring. Suitable for bodyweights up to 17 stone.
Springs are often missold as the 'feel' of the mattress. ie a firm spring equates to a firm feel mattress.

This, on the whole, is incorrect. The spring should only be chosen that to correspond to your bodyweight, as springs are manufactured with weight tolerances in mind, It's the upholstery that's layered on top of this that will give you the true feel of the mattress, ie soft, medium or firm.

Hopefully that helps give you some more detail to assist as you look for new mattresses.
