Hello all, s’me nube personified, with yet another question...So we are moving along with our renovation, and now I am trying to find decent mattresses. As you all know the the sizes of the pullouts are strange. The larger one of ours is 70x75 and the smaller one is 60x75. The old mattresses measured around 4” high. (I read all the info about making sure not to get one that is too thick because the top won’t close, so we intend to do the tissue box test ). But...I have back and neck issues and we want to get good mattresses, that won’t be too hot and that will fit correctly, but don’t want to break the bank. All the ones I have found are either too small or too large. Any thoughts?
