iSense Select Mattress Review

Motion isolation is pretty strong on the iSense Select, especially when compared to some other types of hybrids. The thicker foam layers go a long way toward absorbing movement so your partner doesn’t feel it on the other side of the bed. – Brad

As is standard among the best mattresses for couples, the iSense Select Mattress excels in motion isolation. Its two polyfoam comfort layers significantly limit surface-level vibrations, and the pocketed coil system effectively isolates more significant movements that reach the core.

When we took readings with a vibration sensor, we found that the plush (4) and medium (5) options absorbed motion particularly well. However, the firm (7) also performed very well compared to models with a similar feel.

The foams on this bed were nice and cushy. It took a bit of time and experimentation to figure out which coil sets were the best matches for me, but once I did, it all clicked. I sunk in just enough to take the pressure off my hips and shoulders, and woke up feeling nice and refreshed. – Mary

Thanks to its two-layer polyfoam comfort system, the iSense Select Mattress offers significant pressure relief. While we expect this from most plush (4) and medium (5) hybrid models, it’s less common in firm (7) sleep surfaces. The iSense Select’s polyfoam redistributes body weight well, and the zoning provides more targeted relief and support.

By mapping the pressure using a special pad, we could see that our testers’ body weights were spread fairly evenly across the surface. Team members of all weight groups also confirmed that they didn’t feel notable pressure points.

I was comfy cozy sleeping on the iSense Select and didn’t notice much in the way of heat buildup. It’s a pretty cool bed, overall. – Mary

Hybrid models are often built for cooling, and the iSense Select Mattress follows suit. It includes a fabric cover designed to feel cool to the touch, open-cell polyfoam engineered for airflow, and a breathable coil core. This construction puts the iSense Select Mattress’ temperature regulation on par with most hybrid models.

Our team members reported maintaining a comfortable temperature throughout our testing process, though they felt a bit warmer on the plush (4) surface because of its hug. Temperature readings also showed minimal lingering heat when we removed a heat source.

I was concerned that a bed that lets you remove the coils would have weaker edges. The iSense team predicted this issue and added plenty of extra reinforcement around the edges. They’re pretty solid, regardless of which coil set you use. – Brad

Like most of the best hybrid mattresses, edge support is one of the iSense Select Mattress’ standout features. A foam encasement wraps around the perimeter of the coil system to limit compression that could otherwise make the edge of the mattress feel less secure.

In our tests, team members used the full mattress surface comfortably, including sitting and sleeping along the perimeter. While testers over 230 pounds felt a bit less stable on the plush (4) and medium (5) surfaces, no one reported restricting their movements due to perceived instability.

The iSense Select didn’t feel as bouncy as other hybrids, so it was a bit harder to move around on. The foams are decently thick, squishy, and comfortable so that’s the tradeoff here. I noticed the firmer coil sets gave the bed a little more pushback, so it was easier to move around on those. – Danny

While the iSense Select Mattress doesn’t impede movement, it doesn’t facilitate it to the same extent as many hybrid models. The foam comfort system regains its shape fairly quickly when the sleeper moves. The coils also make the surface fairly responsive models, but the model isn’t especially springy.

None of our team members struggled to change positions on the mattress, and we expect most sleepers will find the iSense Select Mattress suitably responsive. However, some sleepers with mobility issues may find it challenging to change position on the plush (4) option, particularly if they weigh over 230 pounds.

The off-gassing that came from the iSense Select was pretty standard for a hybrid, nothing wild. There was a bit of “new mattress smell” when we unboxed everything in the morning, but it was gone by the time I slept on it. – Danny

The iSense Select Mattress may emit some off-gassing odors, which is normal for models that contain synthetic foam. Mattresses that ship in a box are usually compressed and wrapped right after manufacturing, before they have time to air out. Lingering volatile organic compounds (VOCs) then release in your home after you unpack the mattress.

VOCs have a distinctive odor, though they’re widely considered harmless. If the smell bothers you, you can leave your new mattress in a well-ventilated room to air out.

iSense uses CertiPUR-US certified foam, so it meets third-party emissions standards. While our testers noticed a slight odor when they unboxed the iSense Select Mattress, it wasn’t overpowering. They reported the smell had mostly dissipated after 24 hours.
