## Overview

The Hypnia 12 inch Memory Foam Mattress (Double Size 135x190 cm) features a 3-inch layer of high-density (75 kg/m³) memory foam originally developed by NASA, providing medium-firm support that adapts to your body shape. It includes a removable, washable CoolSoft cover that is hypoallergenic and dust mite resistant, ensuring a clean and healthy sleep environment. With no assembly required and a 10-year warranty, this mattress combines cutting-edge comfort with lasting durability.

## Description

Originally developed by the world's leading scientists at NASA, memory foam has now been adapted to provide the ultimate mattress solution. Memory foam reacts to the warmth of your body and contours to your shape in any position, supporting the areas that need it most allowing you to drift off into deep, high quality sleep. By doing this the pressure of your weight on the mattress is spread over a larger surface area which reduces pressure points and improves blood flow. Memory Foam will always remember its original shape and return to its normal size after each excellent night�s sleep.

*by K***F on Reviewed in the United Kingdom on 30 December 2015*

It arrived this morning and once unpacked let it grow .....and boy did it. It's as deep as advertised and though I have yet to spend the night on it I have high hopes. I am just googling how to successfully pull off a double forward roll to enable my successful arrival on top of the bed tonight as it is a tad higher than.my old mattress. We had a practice nap on it this afternoon and can say it's comfortable and we are looking forward to a decent nights sleep at last.

    They are a terrible company
  

*by C***H on Reviewed in the United Kingdom on 19 October 2016*

BEWARE - I just bought a foam topper directly from Hypnia but the mattress quality and density of the foam is significantly lower than what it should be. They refuse to refund me and now that I've read other reviews online I realise this is not the first time they have conned people. They are a terrible company
