OK, because my wife has Restless Leg Syndrome (and no, that’s not a made up problem. It’s VERY real), we have been sleeping in separate beds in separate rooms. The arrangement is fine for getting sleep and such, but we’d really like to find a way to sleep next to each other again. So we’re looking into mattresses. One option would be to use a split mattress of some sort, like a sleep number bed? We’d almost certainly have to use different covers, but if the whole bed isn’t affected by her movement, I could get better sleep and not have to constantly wake her up.
Another option would be to get two twin beds (or doubles) and put them next to each other.
In any case, we’d like to be able to get a decent mattress as long as we are buying something new anyway. A mattress that minimizes movement and shock would be very helpful for her as well, so she wouldn’t wake herself up as much. She’s tired most days because of this, and the medication isn’t always effective.
