Comfort	Uniquely pressure relieving, we use Memory Plus Foam - a special Helix blend.	Ventilation is the key to sleeping just right - not too hot, and not too cold. Purple achieves the ultimate sleep comfortability by combining a totally new material with a totally unique design. Purple remains temperature-neutral so you don't sleep hot and sweaty at night Purple's column design allows air to flow freely, preventing moisture trapping, extending the life of the mattress, and providing cleaner, more comfortable sleep. Thanks to the free air flow design and patented polymer materials, Purple naturally sleeps much cooler than memory foam, latex, and other mattress technology.
Support	Specially designed using a Memory Plus Foam pressure relief layer to cushion your pressure points as a side sleeper. Density of the top and middle layers optimized to give you the right amount of support based on your body type. High-Grade Polyfoam. Providing ergonomic support and cushioning, the transition layer has a medium IFD to match your body type. Wrapped Coils. Hundreds of individual coils help to cradle your body while also limiting motion transfer. Edge Support. Each mattress has an individually wrapped spring unit with a reinforced perimeter. This means your mattress will reduce that roll-off feeling and will keep its shape more while sitting on the edge of the bed. Our technology is proven to be substantially better than all foam options.	A revolutionary mattress designed for just about everyone. It's designed to not only help you get better sleep, but to soothe joints, release pressure on the hips and shoulders, and support the neck and back. It's designed to make bedtime the highlight of your day! The Hyper-Elastic Polymer Purple is a pressure-releasing material. This material is organized in a grid formation, which creates walls that can support or fold, depending on how much pressure it receives. It's durable enough to last decades so you won't develop a body impression. And it buckles under specific pressure, which provides excellent motion isolation so you don't feel someone else move in the bed.

FAQs

Helix Midnight

How soft is Helix Midnight?

The Helix Midnight has a firmness rating between 4 and 7 out of 10. The feel of the mattress may vary depending on the body type of the sleeper – it may feel medium-soft to heavier sleepers and medium-firm to lighter-weight sleepers.

Is the Helix Midnight suitable for heavy people?

The Helix Midnight offers good pressure relief and helps maintain a healthy spinal alignment, making it suitable for heavy people. However, it may not be supportive enough for heavy stomach sleepers.

Is the Helix Midnight suitable for hot sleepers?

Yes, the Helix Midnight is a good choice for hot sleepers as its coil layer promotes airflow throughout the bed, helping to keep the sleeper cool.

Purple

Why do people like Purple mattresses?

The Purple mattress is favored for its ease of movement compared to many memory foam mattresses. The Purple Grid is both conforming and responsive, allowing for more movement than highly conforming memory foam.

Do Purple mattresses need special sheets?

Regular sheets can be used with a Purple bed, but they must be of the right type. The best sheet materials for a Purple mattress are bamboo viscose and cotton, provided they promote breathability and have the ability to stretch.

What body type is best for Purple mattress?

The Purple mattress is an excellent choice for back and stomach sleepers. However, for heavier back or stomach sleepers, the Original Purple bed may not be the best option.
