Just curious Tracey and Taz Zoee - how are the new mattresses working out? Both my husband and I have the same symptoms Tracey was talking about and we have a new mattress bought five months ago. We're wondering if the new mattress (very firm) is causing the problem. It's outside the guarantee returnable date so we're reluctant to replace it unless we're sure a Tempur-Pedic would be an improvement.
