The Helix Sunset Luxe is the softest side sleeper mattress I’ve slept on — why I’d buy it at up to $749 off this Labor Day

(Image credit: Future) I'm a side sleeper who needs an ultra-plush bed to cushion my shoulders and hips, and that's why I loved sleeping on Helix's softest bed. After sleeping on the luxury hybrid for over two months, I can see why the Sunset Luxe, now down to $1,874 (was $2,498.66) at Helix, is recommended to side sleepers.I wasn't at all surprised by the Sunset Luxe's high quality, as Helix is a brand that features in our best mattress guide. As both a side sleeper and lead tester for the Helix Sunset Luxe mattress review, I was impressed by the relief it provided for my pressure points thanks to its plush, cradling foam layers.So, if you sleep on your side and are shopping for a new mattress, here's why I's buy the Helix Sunset Luxe (plus, why I wouldn't wait until the Labor Day mattress sales are in full swing before buying it).Ultra-plush comfort for side sleepers... (Image credit: Future)Want a mid-range alternative? Try this...When I tested the Sunset Luxe at home and at our sleep lab, I quickly discovered that pressure relief is the highlight of this premium bed. Pressure relief scored 4.07 stars out of 5 as the Sunset Luxe soothes shoulders and hips, displaying the most sinkage out of all the tested mattresses in these key side-sleeping areas.As for subjective feedback, I found the bed to have plenty of contouring, as did my fellow mattress testers. One tester even awarded the Sunset Luxe a perfect 10 or pressure relief.However, stomach and back sleepers will find the Sunset Luxe far too soft. If you're a back and side sleeper, I recommend taking a look at the Helix Midnight Luxe mattress. The Helix Midnight Luxe is No 1 in our best mattress for side sleepers guide, but its medium-firm feel also packs plenty of lumbar support for back sleeping. It costs the same as the Sunset Luxe, too.Whether you choose the Sunset Luxe or the Midnight Luxe, now is the time to invest in a Helix mattress. You don't have to wait until Labor Day itself to rake in the savings, as we've never seen a discount bigger that 25% on the Sunset Luxe.
