Over the last few years, I've been lucky enough to experience the spine-supporting luxury of Helix mattresses first-hand. That's why I was happy to see Helix offer shoppers more of its signature back pain relief with the release of the ErgoAlign Mattress Topper, now $399 for a queen at Helix.

My fellow mattress testers and I have tried all five of the literal slices of luxury known as Helix's cooling mattress topper line-up.

At a glance

  • The Helix ErgoAlign Mattress Topper is designed to support those with lower back pain.
  • The ErgoAlign Layer features high-density foam for extra support around the mid-section, encouraging healthy spine alignment.
  • Our lead tester was impressed with how the ErgoAlign Layer provided immediate relief for her back pain.
  • The cover is made from GlacioTex, a specialist cooling fabric that dissipates heat.
  • While the GlacioTex cover provided cooling comfort, the cover is non-removable and can feel slippery.

Everything you need to know about the Helix ErgoAlign Mattress Topper

In our Helix ErgoAlign Mattress Topper review, we declared the ErgoAlign Mattress Topper not only the best Helix mattress topper for back pain, but the best mattress topper for back pain overall.

First of all, it's the only Helix mattress topper to be endorsed by the American Chiropractic Association, a stamp of approval awarded to sleep products that promote optimal spinal alignment.

This chiropractor-approved support stems from the topper's ErgoAlign Layer. This feature was created by Helix to provide extra support to sleepers who experience lower back pain (we were very impressed when we tried it in the the ultra-comfortable Helix Midnight Luxe Mattress.)

The ErgoAlign Mattress Topper has "targeted support" for all sleep positions, which basically means that it's softer in areas that need cushioning (such as the shoulders and knees) while using high-density foam in areas that need extra support (such as the hips and lower back.)

This firmer mid-section should ensure that the hips and spine are held lifted and straight, preventing the lower back pain that comes with misalignment.

As for temperature regulation, the ErgoAlign Mattress Topper has a GlacioTex cooling cover. GlacioTex is a specialized heat-dissipating fabric found in some of the best cooling mattresses of the year.

The cover also has anchor straps to keep the topper in place, but it's non-removable and the GlacioTex can be slippery.

However, shop around major holidays (such as Black Friday or the upcoming Memorial Day mattress sales) and you'll likely get a queen size for around $364.02 with 27% discount code TOMS27.

What we like about the Helix ErgoAlign Mattress Topper

1. Improves lower back pain

Ok, so let's cover your first question: does the Helix ErgoAlign Mattress Topper actually relieve back pain? Answer: yes.

Our lead reviewer, Alison Barretta, experiences lower back ache and had been sleeping on a bed that exacerbated the pain.

However, when she put the 3"-thick ErgoAlign on an old, thin mattress, she felt instant relief.

"The denser foam in the center offered proper support for my hips and lower back, while the softer zones cushioned my shoulders and knees," she said.

"If you struggle with lower back issues like I do, you'll likely notice an improvement after a few nights of sleeping on it," she added.

2. Sleeps cool

As someone who's tested products with GlacioTex (including the Brooklyn Bedding Luxury Cooling Mattress Protector and the Helix Premium Memory Foam Mattress Topper) I can vouch for how cool-to-the-touch this heat-dissipating fabric is. And lead tester Alison agreed.

"When it came to maintaining a comfortable sleep microclimate, the GlacioTex cover delivered as promised," she said in the review.

3. It's comfortable in all sleep positions

Thanks to the zoned support, the Helix ErgoAlign Mattress Topper is excellent for all three major sleep positions. Its ultra-supportive midsection encourages healthy spine alignment in back and stomach sleepers, while its strategic cushioning along the shoulder section comforts side sleepers.

In fact, lead tester Alison said the versatility impressed her the most.

"My hips remained level while sleeping on my stomach, the softer areas relieved pressure on my joints when side sleeping, and the tri-zone design created a balanced feel when I lay on my back," she explained.

The drawbacks of the Helix ErgoAlign Mattress Topper

There's little to criticize about the Helix ErgoAlign Mattress topper. But one small drawback (which is by no means a dealbreaker) is that the cover of the topper is non-removable and spot-clean only.

While one of the best mattress protectors can help keep the topper's cover stain-free, we've tested plenty of other mattress toppers that come with machine-washable, removable covers, such as the Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper.

Secondly, while I love the cooling feel of GlacioTex, I have to admit that its slippery surface isn't to everyone's taste. It's a slick fabric, and both customer reviews and our testers have complained that their sheets often slide off when placed on GlacioTex.

"This is a matter of preference, but if you're like me, you may find it too slippery," admitted Alison. "Miraculously, my sheets didn't slide off, but I still felt like I was sliding a little."
