In serious winter temperatures, backpackers often use a cheap closed cell foam pad topped with an inflatable thermarest-type pad. The latter are pricey, but bargains can be found on craigslist or ebay.
But a key to sleeping well on an inflatable pad is to put only enough air in it to lift your body off the cell foam underlayer, so it forms a concave or u-shape. Overinlating the pad is a common mistake which results in a concave shape, causing the sleeper to slide off the mat.
