Description

The Sunset Memory 400 matttress from Kaymed is perfect for those who prefer to sleep on a firm and supportive sleeping surface.

Kaymed, the world's leading memory foam specialists are at the forefront of sleep technology. 

The memory foam they use is unique to them and manufactured to their own innovative specifications.

The longevity, resilience and feel of memory foam are dependent on the manufacturers "recipe".

How does this miracle material work?....The high-tech 40mm memory foam layer is temperature sensitive, designed to soften when it comes into contact with warm surfaces.

It moulds itself to the sleeper’s body shape and as a result reduces the pressure points on your body. Less pressure allows better blood circulation resulting in less tossing and turning and a much better night's sleep.

The 160mm base layer of high density foam block creates a solid foundation and offers additional support. The Sunset Memory 400 feels substantial and solid. Covered in a luxurious removable soft stretch fabric cover you feel you are being welcomed to lie down.

Kaymed are so confident in their product they include a 10 year warranty for good measure.

The Sunset Memory 400 mattress is currently on offer at an unbeatable price, so take advantage of this exceptional offer and BUY NOW!

Very difficult since Brexit to source a European King Size mattress in the UK. Archers seem to be the only supplier. Lead time of 4 weeks requires good planning. The product itself is excellent. Firm, but not overly so. Extremely comfortable. Once the mattress arrived to their warehouse they shipped it to me in 24 hours. Good communication throughout the lead time period. I'm delighted with my new mattress and would recommend both the product and Archers.

Dionne Collette - 14 November 2019
The mattresses have been purchased to go onto a daybed & trundle bed. I chose the bed due partly to the fact that both the trundle and day bed accept the same size of mattress which was important to me, especially as when used together they will become a kingsize bed.

As the daybed is designed as a sofa too, the mattress needed to be able to support use for sitting as well as for sleeping, though it is not to be in constant use. I chose this for its firmness as well as its warranty feeling that the manufacturer would not offer such a long warranty in a product that was not likely to last the test of this amount of time. Although only in a spare/guest room come craft room where I will sit to spin yarn & for occasional use quality was essential. I will not be sleeping on them myself but my granddaughter has said she had a comfortable night using it for the first time recently.

Delivered vacuum sealed, they opened up within a short time to their full depth and there was no nasty smells from the materials.
