Under this soft layer, there is a firm, supportive transition layer that will keep your body aligned.

Comparing Sinkage and Bounce

Nolah should offer a gentle cradle that helps the sleeper to float closer to the top of the mattress. As for the Helix Midnight, it too provides a gentle cradle with minimal sinkage. Therefore, most sleepers should feel well supported with little worry about feeling stuck in the bed because they have sunk too far down. When it comes to bounce, the innersprings of the Evolution and the Midnight both provide plenty which comes in handy for combination sleepers and sexually active couples as it allows them to reposition easily.

Comparing Motion Transfer

If you sleep with a rowdy partner, you will definitely want to find a bed that keeps motion transfer to a minimum. The Nolah Evolution should provide you with excellent motion isolation. The substantial amount of foam layers in the Evolution do a great job of isolating the motion made from a co-sleeper and that is why couples may want to pick it over the Midnight. The Midnight performs adequately when it comes to motion transfer, but if one partner is on the heavier side, their other half may be affected by their nocturnal movements.

Comparing Cooling

The coils in hybrid mattresses allow air to flow freely through them and this keeps these beds cooler than their all foam counterparts that can trap heat. In addition to the coils, the Helix Midnight’s standard cover promotes cooling, and you can also opt to purchase the GlacioTex cooling cover for an additional cost. However, when it comes to comparing the two on their cooling properties, the slight edge goes to the Nolah Evolution. In addition to the coils, it also includes the HTC cooling topper, the ArcticTEX™ cover, and AirFoamICE™, which all work to dissipate body heat.

Final Thoughts

These hybrid models have a lot of similar attributes to offer sleepers. Considering that they are both hybrid designs, you should experience the highlights of both foam mattresses and traditional innerspring ones. The Nolah Evolution does provide a more universal firmness that will likely make it a big hit with couples who may not agree on how hard or soft they like the bed. Another potential hit for couples with the Evolution is that it does a better job at motion isolation. However, the Midnight Helix does come in considerably cheaper than the Nolah. Therefore, if budget is a consideration, you may want to lean towards it.
