The Serta iComfort PRO Oxford is a 12.5" plush tight top mattress built with a 5 ZoneResponse™ coil design and graphite-infused True Response™ Latex Foam — Serta’s Level One iComfort PRO construction, using naturally-derived latex instead of standard memory foam as the primary comfort material. It’s designed for sleepers who want the pressure relief of a plush mattress with the responsiveness, breathability, and durability that latex offers over traditional foam. Oxford at a Glance Comfort level: Plush (position 4 of 5: Extra Firm, Firm, Medium, Plush, Ultra Plush) Profile height: 12.5" Top type: Tight top Support system: 5 ZoneResponse™ Design — 5 support zones for targeted spinal alignment Comfort layer: Graphite-infused True Response™ Latex Foam (100% naturally-derived, primary ingredient is rubber tree sap) Cooling: CoolFeel™ Pro System — cool-to-the-touch fabric paired with latex breathability Adjustable base compatible: Yes Certification: CertiPUR-US® certified Assembly: 100% Canada assembled Warranty: 10-year warranty A Good Fit If You’re: A side sleeper who wants plush pressure relief but dislikes the slow "sink and stuck" feeling of traditional memory foam A hot sleeper — latex sleeps naturally cooler and more breathable than memory foam, even before the cooling fabric is factored in Someone who prefers natural, sustainably-derived materials over synthetic foam construction Looking for a more durable comfort layer that resists the body impressions and sagging memory foam is prone to over time Someone who wants a plush feel with more responsiveness and bounce — latex reacts to movement faster than foam does What Stands Out on the Oxford True Response™ Latex Foam is genuinely naturally-derived — its primary ingredient is 100% rubber tree sap, not a synthetic foam blend Latex is inherently more breathable than memory foam, so this plush mattress runs cooler by construction, not just because of the cover fabric 5 ZoneResponse™ Design targets spinal alignment the same way memory foam zoning does, but with latex’s faster response to movement Latex holds its shape longer than memory foam typically does, which means less long-term sagging in a mattress you’ll sleep on for years Plush Comfort, Without the Foam Trade-Offs Plush memory foam mattresses have a well-known downside: they contour deeply but can feel like you’re sinking in, and they tend to run hot. The Oxford sidesteps both issues by building its comfort layer out of latex instead. You get the same soft, pressure-relieving feel plush sleepers want, but with a more responsive surface that doesn’t trap heat or hold onto a body-shaped impression over time.
