If you like your sleep then you should submit a short video to the Embody By Sealy contest for a chance to win a mattress set. Sealy partnered with Polartec to make a healthier mattress to allow for better rest.
I can attest to this. We have been using one for a little over a month now and I no longer wake up sweating each night. Recently I spent a night on our old mattress with our baby and woke up wet in the morning. There is no way a sweaty mattress is clean.
