Questions we get asked about the Serta Radiant

Who is the Serta Radiant best for?

Side sleepers who want plush memory foam, hot sleepers who want the extra gel layer, couples on an adjustable base who want each side to move on its own, and anyone who wants the least motion transfer.

Is the Serta Radiant a good mattress?

Yes. The Serta Radiant is from Serta's iComfort line, zippered-cover model, built on 5 ZoneResponse™ Design foam core, all foam with no coils, with a 10-year warranty and made in Canada with domestic and imported parts. We sell it at 25 to 70% below regular retail, nobody here works on commission, and you're welcome to lie on it in the store before you decide.

What is a split-head mattress?

A queen or king split down the middle from the head to partway down, so each side of an adjustable base can raise its head independently while the foot stays one piece.

Does memory foam sleep hot?

This is the iComfort with the extra gel layer for that reason; an all-foam bed still holds more heat than coils.

Is it good for side sleepers?

Yes. Plush memory foam at the surface with a zoned core underneath.

What is the difference from the Samba?

The Radiant adds the Deep Reaction Max gel layer and comes in split-head sizes.
