Upholstered in a micro quilted damask cover, the Ecoflex from Kayflex is a cheap king size reflex foam mattress that’s robust, durable and one of our best buy 5ft 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.

The king size Ecoflex comes with a choice of mattress depths. Simply choose the depth that suits your needs from the option tab above, before adding the mattress to the basket.

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