We just set up my husband's Bob-O-Pedic foam mattress in the guest bedroom upstairs. I hate it, but he complains that it's the only kind of mattress that doesn't give him back problems. Problem is, it gives ME back problems and since I'm pregnant, I win. We have my regular Sealy in our room right now and I LOVE IT.
Here's the thing, I think he's secretly planning on waiting until I fall asleep and sneaking into the guest bedroom for a better nights' sleep!
Re: Bed Issues...rant.
Give him permission to sleep on his mattress, just ask that he snuggle with you for a bit every night before turning into bed himself. I wouldn't want my husband to suffer (plus he is a bear when he is sick or in pain) when there is a simple solution.
Have you tried maybe putting a board under your side of the bed to firm your side up a bit? I dont know if that works with memory foam but its worth a shot.
And I agree with the PP that said to let him sleep in the bed he likes as long as he spends a little time with you before you fall asleep. Why would you not want him to get a good nights rest if its possible?
This.
