Finally purchased a mattress pad, set of fitted sheets and a fitted blanket for the dinette in my 25.1
$214 custom cut to 46x74x4 for all. Source AB Lifestyles.
In the rear room, I had an upholsterer redo the long cushion on the rear wall into two cushions. The smaller cushion is sized to fill the space next to the twin mattress that is now permanently setup. I also had a cover made to cover the bed during the day.
I also added a Polk soundbar beneath the TV.
There is a powered subwoofer located beneath the bed.
