Who the Serta iComfort Pro Northamptom suits

The Serta iComfort Pro Northamptom is a good fit for back and stomach sleepers who want firm support with a responsive surface, hot sleepers (latex breathes), people with allergies who want a naturally resistant material, and anyone who felt stuck in memory foam. Side sleepers usually want the Oxford or the Surrey.

How the Serta iComfort Pro Northamptom compares

The Oxford is the same latex build in plush. The Portsmouth adds a Euro top in firm. For firm memory foam on coils instead, the PerfectComfort X Pixel.

Questions we get asked about the Serta iComfort Pro Northamptom

Who is the Serta iComfort Pro Northamptom best for?

Back and stomach sleepers who want firm support with a responsive surface, hot sleepers (latex breathes), people with allergies who want a naturally resistant material, and anyone who felt stuck in memory foam. Side sleepers usually want the Oxford or the Surrey.

Is the Serta iComfort Pro Northamptom a good mattress?

Yes. The Serta iComfort Pro Northamptom is a 12.5-inch firm latex bed: True Response latex foam, naturally derived from rubber tree sap, CertiPUR-US certified foams, assembled in Canada, with a 10-year limited warranty. 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.

Why latex instead of memory foam?

Latex pushes back and recovers at once, breathes better, and lasts longer; it is for people who want support and bounce rather than slow contour.

Is it good for back pain?

Firm with five support zones suits back and stomach sleepers. Most backs do best on medium-firm; try the Oxford beside it.

Is latex natural?

True Response Latex is 100% naturally derived from rubber tree sap with no fillers, per Serta.

Does it need a box spring?

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