Sleep Number's winter sale is still going strong, with up to 50% off smart mattresses

Intrigued by dual-zone mattresses, but don't want to overspend? The 9-inch c4 smart bed delivers everything Sleep Number is known for, including adjustable comfort, a ceramic gel cooling layer and a responsive design that adapts to your movements on each side. It also tracks each sleeper, assigning a personalized SleepIQ score and using that data to fine-tune comfort while minimizing disturbances between partners. 

The mattress has earned more than 15,000 five-star reviews. "The ability to adjust the firmness has made a huge difference," one happy fan shared. "My husband is comfortable on his softer side and I'm comfy on my firmer side — without having to put a piece of plywood underneath! Wish we had gotten one sooner."

Yahoo's pick for the best pillow overall, this cushy headrest comes in not one but three shapes (plus two sizes — standard and king) so you can really zero in on the right feel. The classic pillow (shown) is recommended for stomach or back sleepers, while a curved version may be better for side sleepers. Not sure? The Ultimate pillow has three removable inserts that let you customize your support on any given night.

Add two to your cart to take advantage of the 'buy one, get one 50% off' savings.

It's impossible to wake up on the wrong side of the bed with the p5 mattress, part of the Performance Series, which adds a few more layers of thickness with a 10-inch profile and more support and pressure relief. The mattress also doubles down on cooling with two gel layers instead of one. It's great if you want a step up from the brand's classic mattress without going all out.

"After trying many beds, box springs and toppers, I have finally found the one. I have sciatica and spondylosis with fibromyalgia," shared a shopper with chronic pain. "My p5 has been so good for me. My husband surprised me with her and she is the best gift I have ever gotten."

This 11-inch model features even more ceramic gel and 5 inches of comfort layers, designed to enhance pressure relief while helping keep sleepers cool.

Wrote a loyal Sleep Number shopper: "This is my second p6 bed. The bed moves with me, unlike the other one ... I don't have to worry about constant pressure changes. It keeps me comfortable and the fit base is wonderful. I recommend this bed to anybody who really wants a good night's sleep."

The iLE is the most luxurious option in the Innovation Series, with 12 inches of plush layers and advanced cooling features. It also stands out as the "smartest" of the bunch, offering all the brand's core smart features — including built-in sleep tracking and responsive adjustments — along with its highest levels of cooling, plushness and motion isolation. 

"I bought this over a month ago and I feel like a million bucks. The cooling layer, the flex base and the way it responds to my body's needs are amazing. I feel like I won the lottery getting this bed!" one reviewer raved.

This top-of-the-line smart bed earned a spot on the first-ever Yahoo Sleep Awards — it’s the cream of the crop, featuring the brand’s plushest, most supportive layers along with all the other Sleep Number bells and whistles.

"This is by far the most comfortable bed I have ever slept in — bar none. Not only am I more rested and focused, but my back feels better than it has in years. The ability to not only control the firmness and the shape but temperature as well makes going to bed something you look forward to," shared a shopper.
