Hi manateesheriff.

I am sorry that you feel uncomfortable and wake up sore on your new matters.

You do not mention anything about your previous mattress nor the specifics of the zoning in your new mattress but before rushing to return the mattress or trying to fix the wrong issue I’d suggest that you experiment a bit with what you have and try to pinpoint the root cause of your discomfort and sensation of your back being arched.
There may be more than one factor contributing to this and I would first consider a few things.

The one-week-old mattress might not be completely broken in (sometimes it may take a few weeks depending on how taught the cover/encasing is)
Your body has not finished adjusting to the new mattress; (it may be that with your old mattress your body gradually got used to a slightly inappropriate sleeping surface and learned to compensate, which means that a longer adjustment period might be necessary, and that might get worse before it gets better.
A zoned system is may not be appropriate for you. (especially as you are a lightweight back sleeper)
In some cases a mattress that is too firm can also cause anterior pelvic tilt and the lumbar being hyperextended which can cause lower back issues, also the body doesn’t sink in far enough to fill in the gaps in the small of the back in your case (and/or the waist for side sleepers) and the recessed curves of the back can sag which may result in the sensation of “arched back” and the feeling of general soreness that you mentioned that would lead to frequent repositioning and waking up often.
You may also wish to investigate the pillow in combination with your new mattress

The best advice I can offer you is to – give the mattress more time if you can. There will always be a period of retrogression where you lose some of your “learned alignment” to your old mattress, and your new mattress will also lose some of its “false firmness”. You’ve only had the new mattress for a week and it takes time for your body to adjust to the mattress, and for the mattress to adjust to you to (see post #3 here ).

Here are a few things that you could try so that you can pinpoint the cause of your discomfort which might be helpful to determine the best direction to take

I would start with a few nights on your wife’s side and see how your body reacts to it
You could place a pillow underneath your knees and see that makes a difference if it does then the zone underneath your pelvis may be too firm’
You could experiment with a dual-zone (soft & medium Talalay on not-zoned areas of the Pocket coil) l sleeping on the mattress’s width. At your 5’ 9" (69") … a King size mattress 76" x 80" would allow you to sleep across the mattress on its width and experiment with quite a few configurations.
I’d also look into the pillow that you are using as this is essential for part of a good alignment of the head and neck and a pillow that worked well with your previous mattress might be completely unsuitable for your new mattress. The thickness of the pillow should vary with the amount that your upper back or shoulders sink into the mattress.

Once you’ve had the chance to narrow things down a little further, feel free to post back with any specific questions and I or any of our Expert Members we’ll be happy to assist you.
