Hi SergeSurge,
Thanks for your update!
I’m glad that Novosbed was able to get you another product. The new firm model that you received will certainly break-in over time, especially after the first 30 days, so hopefully after that time the mattress has adjusted a bit to you and you’ve also adjusted a bit to the mattress. Of course, you always have the option of the Comfort+ should you need a little extra plushness.
You are correct that your pillow may very well be the issue now for your cervical/upper thoracic region. A firmer mattress will usually not allow you to sink in quite as much, effectively making your pillow sleep a little thicker than it would in a softer mattress. So, you’ll definitely want to do some experimenting with you pillow to make sure that it isn’t too thick for your preferred sleeping posture. There’s some good information about pillows here.
Let us know about you progress with this new mattress after you’ve had a chance to sleep on it for a while and allow it to break in.
