Reminds me of my first apartment's couches, only I had a couple of camp foam mats left over from my 'family' trips that I covered with single sheets from the linen closet that had a different design then the pillow cases. For cushions I used firm bed pillows with the matching colored pillow case. Nothing fancy. It would soften the sharpness in the wood and coolness of the tile. All from items gathered from around.
