Beautyrest Black L-Class: $2,549$2,249 at Beautyrest

Beautyrest Black L-Class: was $2,549 now from $2,249 at Beautyrest
The most affordable in the lineup is the L-Classic. It's still far from basic, with a 13.5-14.5" profile, zoned pocket coils, soothing memory foam, and a layer of plant-based fabric designed specifically to keep you cool for a refreshing night's sleep. Choose from Firm or Medium feels, or amp up the luxury with a pillow-top in Medium or Plush.

Beautyrest Black C-Class: $3,049$2,649 at Beautyrest

Beautyrest Black C-Class: was $3,049 now from $2,649 at Beautyrest
The C-Class is Beautyrest's 'better' option. It has everything you'll find in the L-Class, but also an extra comfort layer made with cashmere, alpaca and silk (all of which are cushioning but naturally breathable) and a layer of latex foam alongside the memory foam. This adds bounce and amps up the pressure relief. Choose from Firm, Medium or Plush feels, or add an extra pillow-top (in Medium or Plush). The profile is a lofty 13.75 - 16".

Beautyrest Black K-Class: was $4,249 now from $3,749 at Beautyrest
The K-Class is the crème de la crème of the Beautyrest Black range. It takes the C-Class model (so soothing memory foam, bouncy latex foam, supportive zoned coils, and a cushioning silk, alpaca and cashmere layer) and upgrades it with another tier of nano-coils for precise body contouring. This one is only available with a pillow-top, and you can choose from Plush or Firm feels. It's up to an ultra-luxurious 16.5" deep.

This was originally a 4th of July sale, but it seems to be sticking around for the moment. There are also big discounts on the Harmony range, which is still supremely luxurious but a bit cheaper, with prices starting at $1,099 on the discounted models. There's still plenty of opportunities to customize your mattress with different sleep feels, pillow-top options and cooling upgrades to choose from. All Beautyrest mattresses include a 100-night in-home trial, white glove delivery, and 10-year limited warranty.
