The Helix Midnight Luxe is our favorite mattress overall. Everything we love about the bed earned it the top spot in our king mattress shopping guide as well. The hybrid design is great for a variety of sleepers—including back, side and combination—as well as sleepers with back pain. It has a thick pillow top (which was recently increased in size by the brand) that helps give the bed a comfy, balanced feel and excellent motion isolation.
More Deal Information: Helix offered 30% off earlier this year, but this exclusive reader code matches the best discount we've seen since then.
Supportive and affordable (even when it's not on sale), this hybrid design is our favorite king bed for back and stomach sleepers, as well as our pick for the best value mattress in our main mattress shopping guide. The classic design conforms to your body and helps regulate temperature while you sleep. Its medium-firm build leans to the firmer end of the spectrum, making it easy to move on and great for sleepers who want a little extra support. It also delivers excellent motion isolation—something couples will appreciate.
More Deal Information: This bed dropped to $799 during the brand's Spring Flash Sale this year. However, the original price of the mattress has increased since then from $1,898, so it may not reach that low again any time soon.
If you struggle with back pain, consider the Saatva Classic. The innerspring design is our favorite mattress for back pain overall. It has a dual-coil construction and multiple layers of targeted lumbar support that make it an ultra-supportive mattress, especially for back sleepers. While the design gives you a buoyant feel, it did not score as highly during our tests for motion isolation, but it does excel at edge support. The bed comes in three firmness levels, so you can customize it to your preference. (I own the luxury-firm and love it.)
More Deal Information: Although the brand increased the original price of this mattress in 2025, it rarely exceeds $400 off, even during major sale events. This discount is one of the better prices we've seen this year, just shy of the $2,210 low at the end of March.
Classic memory foam offers coveted features—like excellent motion isolation and contouring pressure relief—but it's known for retaining heat. This Tempur-Pedic model is designed with cooling properties that help with temperature regulation while you sleep, like a cool-t0-the-touch cover, so you're not as likely to overheat. Heavier sleepers or anyone searching for a bed that delivers extra support may find a better fit with a more supportive hybrid design.
More Deal Information: This discount is small, but it matches one of the better prices we've seen for this model in the king size.
This Leesa mattress blends springs and memory foam to create a cushy, hybrid design that's as supportive as it is comfortable. It has a bouncy feel that one tester described as 'plush and airy but on the sturdier side of the scale." Not only is it our favorite king-sized hybrid bed, but it's also our favorite hybrid mattress overall. It accommodates all sleeping positions, offers great edge support and includes cooling properties to help regulate temperature all night long.
More Deal Information: This model was available for $1,919 earlier this year. Leesa also offered 30% off select models over the July 4th holiday, but the brand increased the original price of this mattress as well. If you're willing to wait, we may see an additional drop on this design.
While many brands offer cooling additions to their mattresses for an added fee, this Brooklyn Bedding design comes with a GlacioTex cooling cover built in. Besides hot sleepers, this cool-to-the-touch bed is also great for side, back and stomach sleepers. The model comes in three firmness levels for added versatility: We recommend the soft model for side sleepers looking for superior pressure relief and the medium or firm for back and stomach sleepers, depending on their overall preference.
More Deal Information: This model was available for 30% off over the July 4th holiday, so it may be worth waiting for Labor Day weekend to get the best price.
Couples and side sleepers—especially those with hip or shoulder pain—will get the most out of this Nolah mattress. The bed delivers several layers of support and comes in three firmness levels to accommodate different sleeping preferences and body types. For instance, we recommend the plush model for dedicated side sleepers who don't change positions much throughout the night.
More Deal Information: Nolah often offers 35% off over holiday weekends, so you may be able to score a little extra savings if you're willing to wait.
