Wamsutta Eventemp Mattress Pad, $100 for queen

What It Provides

A substantial amount of high-tech poly-fill (eight ounces per square yard), which offers temperature-regulating properties similar to those of wool at less than half the cost.

Why We Like It

You won't feel too warm or too cold with this poly-fill pad. The NASA technology behind it works by trapping excess body heat and then releasing it into the bed when your body temperature lowers during the night. The top fabric is soft to the touch and made with 250-thread-count cotton. It's not as plush as a wool pad, but it still adds a significant layer of padding. The pad is machine-washable, and the skirt stretches to fit 17-inch-thick mattresses.
