Description

The Ecoflex king size mattress is manufactured in the UK by Kayflex and combines a durable reflex foam interior, a micro quilted damask cover and a soft, yet supportive sleeping surface.

Reflex foam mattresses are extremely hard wearing and offer a high level of antimicrobial and dust mite resistance, an ideal sleeping environment for allergy sufferers or asthmatics.

Although the Ecoflex mattress is one-sided and does not need to be flipped over, we do recommend that you rotate it regularly from head to toe to even out the wear and tear.

The mattress will be delivered to you, vacuum packed in a roll and when fully unpacked they fill out to their full and permanent size providing a supportive sleeping surface for many years to come.

The Ecoflex is a cheap king size reflex foam mattress that is supportive, yet soft and extremely comfortable and on offer for a very affordable price.

Excellent customer service and recommendation from Elaine at Archers internet sales. Prompt attention that met our urgent need for pre-xmas delivery was greatly appreciated. We required a soft medium option and this is an excellent fit for our needs. A well made product in reactive foam.

Claire von Simson - 15 August 2017
Bought this mattress to go with our reinforced divan bed. Convenient in its rolled up state and opened out to a nice comfortable firm mattress within a few minutes a bit like a memory foam does. Son took a few nights to get used to a firm mattress after having slept on a different type for years but now loves it and wouldn't have any other type. Came separately to the bed but within minutes so I was impressed by that so well done whoever co-ordinated those deliveries!
