Serta Featherby Cushion Firm Mattress Sets

Layers of supportive foam, cooling gel, and individually wrapped coils create a medium-firm mattress perfect for those with sensitive necks and lower backs. Cool Twist gel memory foam conforms to every angle of your reclining figure and helps disperse heat to keep sleeping temperatures low. Deeper in the mattress, past layers of pillow-soft and firm foam, individually wrapped coils offer support to backs and necks while easing up on hips and shoulders.

About Serta

In the 1930s, an assembly of independent mattress manufacturers joined forces to form a robust company with a focus on quality. From the outset, Serta’s created originals, such as the first-ever tuftless innerspring mattress. Continuing down that road, they introduced the Sertapedic in the 1950s with the tag line “You sleep ON it, not in it” in response to demand for firmer mattresses. Over the subsequent decades—as Serta innovated continuous innersprings, gel memory foam, and filling that felt just like sleeping on dodo feathers—the brand’s commitment to quality and innovation never wavered. Today, their mattresses cradle sleepers in more than 100 countries.
