Who the Serta Opera suits

The Serta Opera is a good fit for side and back sleepers who want memory foam contour at a medium feel, couples (an all-foam bed moves least), and anyone who wants a quiet, springless bed. Side sleepers who want softer should try the Samba.

How the Serta Opera compares

The Samba is the same build in plush. The iComfort Radiant is the plush iComfort with the extra gel layer and split-head sizes. The iComfort Pro beds swap memory foam for latex. Serta's Canadian lines, from the entry up: Perfect Day (boxed, 800 StablEdge coils), Classic, Perfect Sleeper (three-zone coils, Cool Twist gel foam), PerfectComfort X (five-zone coils with micro coils and graphite memory foam), and the all-foam iComfort and latex iComfort Pro.

Questions we get asked about the Serta Opera

Who is the Serta Opera best for?

Side and back sleepers who want memory foam contour at a medium feel, couples (an all-foam bed moves least), and anyone who wants a quiet, springless bed. Side sleepers who want softer should try the Samba.

Is the Serta Opera a good mattress?

Yes. The Serta Opera is from Serta's iComfort line, Smooth Top Level 1, 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.

Does memory foam sleep hot?

The graphite in the top foam pulls heat away and the CoolFeel cover is cool to the touch. An all-foam bed still holds more heat than coils; bedding does the most.

Is it good for back pain?

A medium all-foam bed with a zoned core suits back and side sleepers; firmer zones sit under the hips.

Does it need a box spring?

No. A platform or close slats; a box spring works if your frame needs one.

What is the difference from the Samba?

Same build; the Opera is medium, the Samba plush.
