If you’re looking for a new mattress that will save you the dread of hot summer nights, try sleeping cooler on Purple. Our CNET sleep experts have been testing, reviewing and recommending Purple mattresses for quite some time. Senior producer and sleep writer Owen Poole even slept on one for five years.

When you think of a brand that makes beds in a box, Purple probably comes to mind. OG fans may even remember the iconic Purple Boys ad from 2018 for Ideal Sleep Solutions and Zonk Strategies, a quirky YouTube video commercial that we still occasionally reference to this day.

In addition to implementing unique marketing strategies, Purple also has something no other bed manufacturer on the market has: a patented GelFlex Grid made of hyper-elastic polymer. This gel-like material is cushioning yet supportive to support your pressure points while keeping your spine and neck straight.

This GelFlex Grid doesn’t retain body heat like foam and other materials commonly used in mattresses. While we wouldn’t call it overtly actively cooling, its air channels make the bed more breathable and ensure your temperature stays regulated throughout the night.

Rejuvenate Luxe Collection: Mattresses up to $500

You can save $500 on any mattress in the Rejuvenate Luxe Collection, Purple’s highest-end beds. This brings the price of a luxurious queen-sized Purple Rejuvenate down from $5,495 to $4,995. If you want to invest in Purple’s most expensive and premium mattress, the Purple Rejuvenate Premier, you can save up to $800 when combined with a Smart Base. This brings the total price of the package down from $9,390 to $8,590.

Because of the cooling quilted comfort cover and dual layers of foam over the GelFlex Grid in the Rejuvenate Luxe mattresses, the squishy feel of the Purple Grid isn’t as noticeable compared to the mattresses in the other two collections, which can be a good or bad thing depending on your personal preference. If you’re not sure about the Purple Grid, you can order a small sample of the Purple Squishy for $3 to get a feel for it.
