3 king mattresses to buy this Black Friday, starting from $899

We described this medium hybrid bed as "the most impressive, budget-friendly mattress we’ve tested," in our DreamCloud Classic review. We found it cushioning and supportive in most sleep positions ( though stomach sleepers may need something firmer), it regulates temperature well and has solid edge support, so you won't feel like you're falling off the bed if you sleep close to the perimeter. For Black Friday, you can get a king for $899, which is the typical sale price, but the free sleep bundle worth $599 is a great extra. It includes two pillows, a sheet set, and a mattress protector. Plus, you'll get 365-night trial, free delivery and a forever warranty.

The Nectar Premier is our best memory foam mattress, and in our Nectar Premier Memory Foam mattress review we found its medium-firm feel provided just the right pressure relief and support for side and back sleepers. Our testers found it plush and cushioning, with the 'hug' you'd expect from memory foam (there's an extra inch of it compared to the Nectar Classic), yet it doesn't trap heat for an all-foam bed. Right now, a king is $1,099 in Nectar's Black Friday sale. While this matches regular Nectar mattress sale prices, it's still excellent value for the bed that is our favorite of the many all-foam models we've tested, and one that comes with great benefits: a 365-night trial, free shipping and a forever warranty.

The options so far haven't been great for those who sleep on their front. So here's the dual-sided Plank Firm mattress — one side is Extra Firm and the other is Firm — which provides unbelievable support for stomach and back sleepers. Despite being an all-foam bed you'll sleep on top of it, rather than sinking in, and it's supportive right up to the edges. The lack of cushioning does mean it's not ideal for side sleepers, and hot sleepers may want to upgrade to the GlacioTex cover. There's currently 30% off the Plank Firm for Black Friday, bringing a king down to $1,072.40 (was $1,532). You'll also get free shipping, a 120-night trial and a limited lifetime warranty.
