This is a great  mattress. Comfortable and it does not as a memory foam make you sweat. Really supportive of the back and as a side sleeper I feel it holds my body in a really comfortable posture all night.
However! And this is the reason I am giving it a low rating- the off gassing!!! The amount of chemicals that must have been used in this product has given me headaches the last few nights.  This even after leaving outside in the sunshine for 2 days the smell still continues to be too strong.
I wonder when Emma designed the mattress to support a healthy nights sleep she even thought about the toxic overload a human body has to sustain while using this product.
Such a shame that more care is not taken for the overall experience of this mattress and I wish to god I had learnt more about off gaming before purchase.
Are we not swamped with enough toxic chemicals as it is. Now we have to bring it into our very homes!
