Description

Upholstered in a micro quilted damask cover, the Kayflex Ecoflex Firm is a low cost super king size reflex foam mattress that’s robust, durable and one of our best buy 6ft foam mattresses.

Reflex foam mattresses are a cheaper alternative to memory foam and offer the same high level of antimicrobial and dust mite resistance; an ideal sleeping environment for allergy sufferers.

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

For ease of delivery, it will be delivered to you, vacuum packed in a roll. When fully unpacked they fill out to their full and permanent size providing a supportive sleeping surface for many years to come.

If you are looking for a cheap super king size foam mattress in a hurry, the Ecoflex Firm from Kayflex certainly fits the bill. It is on offer for a very affordable price and is available on a FREE next day delivery service.

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!
