Mattress for New Room

Is time to check out custom mattress deals now. I asked elder daughter yesterday whether she wants a single mattress or queen size mattress for her new room. I personally prefer queen size bed for them, so that they could sleep more comfortable. But she told me she wants a double-decker bed! She wants to sleep upper deck and sister sleep at lower deck. Hmm… I haven’t made up decision which to buy yet..Let’s see what kind of best deal I could find for them.
