A friend went mattress hunting the other day and found this.
"Airedale Luxury Firm
The Airedale Luxury Firm is a Stearns and Foster mattress known
for its cushy-yet-firm feeling. This comfortable mattress includes
temperature regulation, thanks to its silk-infused, luxurious cover. It
features PrimaSense Gel-Memory foam support with added high density
foams. With a firm feel and plenty of support, this Stearns and Foster
mattress is a great choice for sleepers looking for a nice blend of soft
and firm support."
