The Helix World Sleep Day sale is live — the 5 products I'd buy to sleep cooler and comfier, all night long

The Helix Midnight Luxe reigns as the best mattress for side sleepers we've ever tested. With a medium-firm tension and a lush pillow top, it delivers a keen balance of pressure relief and support to prevent common side sleeper issues like dead hips and sore shoulders. However, if you deal with frequent lower back pain, I recommend adding the ErgoAlign Comfort Layer for extra lumbar support. I slept on the Helix Midnight Luxe with ErgoAlign during my travels and didn't experience the typical aches I deal with when I'm away from home. (Surprisingly, I found this mattress just as comfortable on my back, too!) Use code TOMS27 to see this final price. Helix includes a 120-night trial and a lifetime warranty with purchase. White glove delivery is also available for a fee.

Maybe your mattress is in good shape and just needs a little extra support in the right places. That's where the Helix ErgoAlign Mattress Topper comes in — it's the same layer found in the upgraded Helix Midnight Luxe, with a firm middle to support the lumbar and plusher zones to relieve joint pressure. (The soothing GlacioTex cover is a nice touch to wick heat and moisture away.) I placed this topper on an old, flat futon and it was such an improvement that I started preferring it over my regular mattress! It's the best mattress topper for back pain we've tested, and during the Helix Sleep Week sale, you can grab it for 27% off with code TOMS27. It also comes with a 1-year warranty and a 120-night sleep trial.

I'm approaching a time in my life when night sweats are starting to become a common thing. Putting a bag of frozen veggies on my forehead can only work for so long, which is why I'd sooner go for the new Helix ComfortAdjust Cooling Pillow. The cover is made from GlacioTex, which is a heat-conducting material that's cool to the touch. Better yet, I can adjust the loft by adding or removing the shredded memory foam and fiber fill, and even adjust the firmness of the pillow through a couple of side zippers. Although it was just released, it's already 27% off with code TOMS27. It comes with a 1-year warranty and a 30-day returns window.

Sometimes, I need to put a pillow between my knees to relieve pressure from my lower back, but it's not always the most convenient solution, especially when I move around a lot. This Helix Side Sleeper Knee Pillow has an ergonomic design to contour my knees and legs — plus, it has a strap to keep the pillow in place. It's small enough to travel with, as well, so I'll no longer have to suffer from the fallout of being stuck with an uncomfortable hotel bed. Use code TOMS27 to knock 27% off the list price. It's backed by a 30-day money-back guarantee and a 1-year warranty.

Think of your bed sheets as that necessary finishing touch for your mattress and pillow. I've become fond of bamboo-cotton blend sheets because they're soft and breathable, but they're also durable enough to withstand multiple washes. These Helix bed sheets are a 60/40 blend of cotton and rayon from bamboo, with a 300 thread count that makes them suitable for year-round use. They're available in white, silver, or khaki — and with code TOMS27, you can save 27% on all sizes and colors.
