If you're looking to upgrade your guest bed in time for Christmas, the 4" Sleep Innovations Ultrasoft Gel Memory Foam Mattress Topper makes it easy. The queen size is $109.98 (was $129.99) and the Cal King is $127.49 (was $149.99).

This is not a 4-inch-thick board of gel memory foam, but a two-part topper consisting of a 1-inch removable pillow top and a 3-inch foam layer. Still, the Sleep Innovations Ultra Soft Gel Memory Foam Topper has more than 23,000 user reviews on Amazon, with an average rating of 4.5 out of 5 stars.

It is a good choice for softening visitor beds, and many users love it for relieving pressure points in the back and hips. However, we would argue that the Tempur-Pedic Tempur Topper Supreme (from $299 on Amazon) is the best mattress topper for those with joint pain. It's pricey, but it has three inches of award-winning, NASA-developed Tempur to cradle your body.
