Worth the investment!

I had to leave a review for this! My husband and I love our helix midnight lux mattress. Its been great to sleep on. The medium firm was a bit firmer than we anticipated but as we kept testing it out for a few weeks, & it definitely formed to the shape of our body. My husband gets up early for work and it would wake me up but with the helix, we can barely feel each other's movements. Also no more back pain or restless nights!

I'm a person that's 5'

I'm a person that's 5' 8" and weigh in around 400 lbs. This mattrass was a game changer for me, as it has help improve my sleep and improve the pain from my problem with sciatica that was not a nice thing to go through. I'm very happy with the mattress I purchased. The only thing I didn't like that much was the price, but then everything is so high.

The Perfect Balance of Softness and Support

I purchased my Helix Midnight Luxe in May 2026, and I absolutely love it! After using a mattress pad for the past six to seven years, I finally have a mattress that's comfortable enough on its own. It strikes the perfect balance between softness and firmness, and I haven't felt the need to add a mattress pad since purchasing it. I'm very happy with my purchase!
