Labor Day has come and gone, though there's still time to cash in on mattress savings. Top brands like Casper, Nectar and Helix have extended their Labor Day sales for the next few days. Right now, Helix is offering a 25% off sitewide sale, but that's not the best deal you can get from Helix.

We have a CNET-exclusive deal from Helix that beats the standard sale. It's 27% off the Helix website with two free pillows with any mattress purchase when you use the code CNET27 at checkout.

I know what you're thinking: that's only 2% more. But let me put that into perspective. A queen Helix Sunset Luxe mattress, our pick for the best mattress for pressure relief, normally costs $2,374. The base 25% off sale drops a queen's price to $1,780. That's $593.50 in savings. 

Already, that's a pretty good deal, especially for a mattress as comfortable as the Helix Sunset Luxe. The extra 2% from the CNET-exclusive deal earns you $640.91 in savings and decreases the price to $1,732. That's an additional $47.41 saved. The two extra pillows with your mattress only sweeten the deal.

This exclusive sale isn't just limited to the Sunset Luxe. It's across the entirety of Helix's website. While I wouldn't say these mattresses are cheap, Helix makes some of the most supportive and comfortable beds you can get. It's nice to see a sale like this across all Helix beds. 

Helix's mattress catalog is so large that everyone has a bed that suits their needs. For example, the Helix Plus is one of the best mattresses for heavy people you can get. Side sleepers should consider the Helix Sunset Luxe and couples will like the Helix Moonlight Luxe. Just don't forget to use CNET27 when you check out.
