High thread count, all the way.
I stayed at a Ritz-Carlton hotel once and I loved their pillows so much I bought one - you can buy them at their web site, but they're Pacific Coast and you can pick them up elsewhere. They also had a down bedcover, and a down comforter. I could have just stayed in bed all day. Better still if I'd had Ratbastid there with me
Chenille throw pillows are cheap and add some texture and they feel very sensual.
Other stuff around the bed is important, too, like candles and such.
