Detailed Description

Medium-firm comfort | Copper-Gel Infused Memory Foam | Responsive Reactive Foam | Patented Edge Support | Breathable Air Grid™ Base

Experience Responsive, Recovery-Focused Comfort

The ActiveAlign 10" Reactive Copper Medium-Firm Foam Mattress is designed to deliver the balanced support, responsive comfort, and cooling performance needed for deeper, more restorative sleep. Its combination of copper-gel infused memory foam, latex-like Reactive Foam, and a breathable Air Grid™ base creates a comfortably supportive sleep surface that responds naturally as you move.

Whether you live an active lifestyle or simply prefer a mattress that feels supportive without being excessively firm, the ActiveAlign provides pressure-relieving comfort with dependable stability from edge to edge.

Cooling Copper-Gel Comfort

A 1" layer of copper-gel infused memory foam gently conforms to the body to help relieve pressure while pulling excess heat away from the sleep surface. Its cooling and antimicrobial properties help create a fresher, more comfortable sleeping environment throughout the night.

Responsive Reactive Foam

A 2" layer of Reactive Foam provides latex-like responsiveness and bounce-back without the deeply sinking sensation associated with traditional memory foam. This medium-firm comfort layer supports healthy spinal alignment while making it easier to reposition during the night.

Patented Edge Support

The Patented Edge Support System reinforces the mattress perimeter to create a more stable sitting surface and approximately 20% more usable sleeping space. This added reinforcement helps maintain consistent support across the mattress, including near the edges.

Reinforced Support Layer

A 2" support foam layer strengthens the comfort system and provides additional reinforcement beneath the responsive upper layers. This transition layer helps distribute body weight evenly while maintaining the mattress’s balanced medium-firm feel.

Breathable Air Grid™ Base

The 5" Air Grid™ base is constructed with durable 1.8 lb. foam and articulated cuts that encourage airflow throughout the mattress. Its flexible yet reinforced design also allows the mattress to move naturally when paired with an adjustable base.

Built for Convenient, Restorative Sleep

The ActiveAlign features a zip-off, machine-washable cooling cover that makes it easier to maintain a clean and comfortable sleep surface. Its all-foam construction offers consistent support without the motion or noise associated with a traditional innerspring system.

The mattress is also compatible with adjustable bases, which are sold separately.

Who Should Choose the ActiveAlign?

The ActiveAlign 10" Reactive Copper Medium-Firm Foam Mattress is an excellent choice for:

  • Back sleepers seeking balanced spinal support
  • Side sleepers who prefer a supportive, medium-firm surface
  • Active individuals focused on rest and recovery
  • Hot sleepers looking for cooling copper-gel foam and enhanced airflow
  • Sleepers who prefer responsive comfort without excessive sinking
  • Couples who want stable, edge-to-edge sleeping space
  • Adjustable-base owners who need a flexible all-foam mattress

Balanced Support Without Compromise

The ActiveAlign 10" Reactive Copper Medium-Firm Foam Mattress brings together cooling pressure relief, responsive comfort, reinforced edge stability, and breathable support. The result is a restorative sleep surface built to help you wake up refreshed, supported, and ready for what comes next.

BEFORE

AFTER

I used to sleep on the edge of my bed and felt like I was falling off every night. I was desperate for something that would actually support me there. Finally invested in a quality mattress and the edge support is incredible. It's firm enough for real support but not uncomfortable. A couple months in and I wake up feeling great with no aches. Totally changed my sleep for the better!

BEST SLEEP EVER

I've been sleeping on wrong mattresses forever and this is a game changer. My back doesn't hurt anymore when I wake up. The comfort is absolutely unreal.

- Derek K.

BEST MONEY I SPENT ALL YEAR

Seriously this was the best purchase I made in 2025. The comfort level combined with how long it stays firm is insane. Already telling everyone about it.

- Jennifer A.

NO MORE PAIN

No more waking up with shoulder and hip pain. Used to dread getting out of bed but now I actually feel rested. The support is real, not just marketing talk.

- George W.

LIFE CHANGING

Wasn't ready for how good this would feel. The softness on top with the support underneath is exactly what I needed. My partner loves it just as much as I do honestly.

- Audrey B.

SLEEPS SO MUCH COOLER

No more feeling like I'm cooking at night. This mattress breathes way better than what we had before. I actually stay asleep now instead of waking up sweating.

- Charles P.

THE QUIZ REALLY WORKS

I wasn't sure what firmness I needed but the quiz actually got it right. Saved me from buying the wrong thing. Really impressed with that tool.
