The Serta iComfort Iona Plush Mattress is built for sleepers who want a luxurious, deeper profile paired with a soft, cradling surface. To begin with, it brings together a cool-to-the-touch cover with several layers of premium memory foam to deliver restorative, rejuvenating sleep night after night.

Next, the feel is decidedly soft. As a soft Serta iComfort mattress USA customers can shop online, the Iona Plush is purpose-built for shoulder, hip, and lower-back pressure relief, making it a top contender for the best plush mattress for side sleepers with hip pain.

Moreover, the cooling system is engineered into every layer. A graphite-infused memory foam layer combined with gel-infused EverCool® Fuze foam and a Cold Touch breathable cover creates a cooling soft memory foam mattress for hot sleepers who often overheat at night.

Because of this layered approach, the bed delivers cloud-like pressure point relief, advanced cooling for restorative sleep, and a luxury 13-inch high profile feel that anchors the bedroom with hotel-quality presence. The result is consistent comfort and targeted cushioning for shoulders and hips in every sleeping position.

Finally, this 13 inch plush memory foam mattress is backed by a 10-year Serta limited warranty and built to CertiPUR-US certified foam standards.
