Foam names can make mattress shopping feel more complicated than it needs to be. In the ADAPTIV lineup, memory foam and response foam are distinct listed layers within a larger hybrid construction. The right way to compare them is to look at the complete mattress—its feel, other comfort materials, coil system, and shopping path—not to judge a model from one foam name alone.
Quick summary: Horizon Firm lists AeroTherm Cooling Gel Memory Foam. The Ascent and Summit models list named response foams as part of more layered constructions. Start with your preferred feel in the ADAPTIV mattress finder, then use the materials below to make a more informed comparison.
Memory foam in Horizon Firm
Horizon Firm lists AeroTherm Cooling Gel Memory Foam below its ELEVAIRE Cover featuring AeroSync Climate Management. Its remaining listed layers are ComfortBridge Support Foam, a MATRIX BASE Precision Coil Array, and SupportCore Base Foam. This is the firm option in the current lineup, so compare its listed memory-foam layer alongside its focused feel and complete foam-and-coil build.
Response foam in the Ascent family
Ascent Medium lists ADAPTIX AirFlow+ 5-Zone Response Foam, while Ascent Luxury Plush lists ADAPTIX AirFlow+ 5-Zone Plush Response Foam. Both models also list AeroSync Recovery Foam with Zoned QuickCool PCM, a cooling gel foam layer, ComfortBridge Transition Foam, and a MATRIX BASE Precision Coil Array with ATLAS Support Edge.
The response-foam name is one construction difference between these two Ascent options. The broader choice is still the surface profile you prefer: Medium or Luxury Plush.
Response foam in the Summit family
Summit Luxury Firm lists ENERGIX AirFlow+ 5-Zone Response Foam as part of a build that also includes AeroTherm Elite Cooling Gel Foam with Zoned QuickCool PCM, ADAPTIC ExtendiCool Climate Bands, NanoFlex Zoned Microcoils, ComfortBridge Support Foam, and a MATRIX BASE Precision Coil Array with 2X ATLAS Support Edge.
Summit Ultra Plush lists ADAPTIX AirFlow+ 5-Zone Plush Response Foam, NanoFlex Zoned Plush Microcoils, ComfortBridge Plush Support Foam, and a plush MATRIX BASE Precision Coil Array with 2X ATLAS Support Edge. It is retail exclusive, so use its product page for the appropriate retailer-oriented shopping path.
Compare the full construction, not one material
- Choose a surface feel. The current lineup ranges from Firm to Medium, Luxury Plush, Luxury Firm, and Ultra Plush.
- Read the listed layers together. Memory foam, response foam, cooling materials, microcoils, transition or support foam, and precision coils each appear in a specific model build.
- Check the exact model details. Visit the mattress comparison to review the current lineup side by side, then open the relevant product page for its full listed construction and availability.
Material names are useful signposts, but they are only one part of the decision. Use the mattress finder to narrow the lineup, compare the models side by side, and follow the product page that matches the feel and construction you want to explore.
