ActiveX Review

Introducing the ActiveX from Nest Bedding.  Nest Bedding is a rapidly growing online mattress company with several offerings.  They are also a brand we highly recommend since they continue to release high end well built mattresses with great prices.  The ActiveX uses a Phase Change Cooling Cover and several foams designed to make this perhaps the “coolest” mattress you can buy. 

You will like ActiveX Mattress if you:

  • Like to sleep cool – ActiveX is specifically designed to sleep cool and that is how it performed for us.  We did not experience excessive heat at all. (see the video for thermal testing)

  • You want a good value – ActiveX packs a big punch with premium foams and fabrics for under $1000 in a queen.

  • Sleep in multiple positions – This mattress is a good medium feel with good body conformance.  Sleeping on your side, back or stomach ActiveX will conform to your body very well.  It is a true medium feel.

  • Are a heavier sleeper – When compared to a 10″ mattress the ActiveX is a good option if you are a heavier sleeper as well as light.  It also uses good components that ensure you don’t bottom out like some thinner mattresses can.

  • Like the combo of bounce and body conformance – We didn’t get a sinking or stuck feeling on the ActiveX.  So you can adjust positions pretty easily.

You might not like the ActiveX Mattress if you:

  • Do a lot of activities sitting on the edge of the bed – Sitting on the edge the mattress sinks down about average for a foam bed.  If a very sturdy sitting edge is important to you you may want to consider something with foam encased edges or a border wire (coiled/spring mattress primarily). Laying on the edge was not an issue however, you still have the entire sleep surface usable.

  • Want a innerspring mattress – It can take time to get used to a foam mattress, if you already know you don’t like all foam mattresses you should stick with a coiled mattress. The ActiveX is a comfortable mattress but it won’t probably transform you from a spring fan to a foam fan.

  • Have a tight budget – Although this is a nice mattress for the price if you want to spend less than $999 you’ll need to shop around.

ActiveX Mattress Cover

ActiveX uses Phase change fabric and is known for its ability to absorb & store body heat, helping you maintain a temperature better for deeper sleep. This cover acts as a temperature regulator.  Its designed to keep you temperature neutral, not too hot, not too cold.  It is constructed with a thinner build, allowing for better air circulation as well.

ActiveX Mattress Foundation

The ActiveX Mattress will work fantastic on any solid surface.  A wood foundation/boxspring, slats, the floor and will work great on an adjustable base.  See the video below.

His and Hers – Firmness and Feel:

My thoughts (Ross)

ActiveX is the 3rd Nest product we have reviewed.  Once again they have proved to build quality products.  They set out to design this mattress to sleep cool.  For us it did.  In addition I am a person who likes to sleep in all positions.  The ActiveX performed well for all 3.  It conformed well without being too soft as well.  You feel good body conformance while maintaining a nice floating feeling without sinking in too far and feeling stuck.

Her thoughts (Kayla)

Sleeping cool for me is not a problem but it did seems to stay cooler.  For me I like a soft mattress since I’m a lighter person at 125lbs.  The ActiveX was a good firmness that still felt like it supported me great even though I didn’t sink in very far.  The motion transfer was very minimal as well.  Overall, we liked the mattress and all of the other Nest beds so far.

Softness-Firmness level: 6
1 Very Soft
5 Medium
10 Very Firm


Phase Change Fabrics, ActiveX Luma Cooling Foam, Air Flow Layers and Sports Performance Design Elements makes the ActiveX Mattress sleep cool.  In our sleep trial the mattress slept cool.  See our video review above we have a thermal camera heat test that also show how quickly heat dissipates from the mattress.

Overall Summary

I would recommend this mattress for all body weights and sleeping positions. The core foam they use is denser then most of the brands online so this mattress would be good for heavier people as well when compared to a mattress with a less dense core. For those of you who sleep warm this is a must try.
