Fabric swatch and mattress suitability

Is it possible to get fabric swatches sent out as it's difficult to see the exact colour and texture in the pictures?
We are interested Taupe Hopsack, Hazel Bracken and Silver Hopsack.
Also we are interested in the Ottoman king size bed base, however we are in the process of ordering a Tempur Original Deluxe 22 Memory Foam Mattress, King Size mattress elsewhere and wondered if this bed base is suitable for the mattress?
