The Helix mattress protector is a comfortable and breathable fitted-style mattress protector that could be the perfect complement to a Helix mattress (or another type of mattress no more than 15” thick). Read on for my full review and personal experience with the protector.

Who Is This Ideal For?

Helix says their mattress protector will fit any mattress (that’s no more than 15” deep) but it is specifically designed with the Helix mattress in mind.

The top knit fabric is designed to mimic the fabric on top of the Helix mattress in addition.

Overall, this could be potentially a good fit for anyone looking for a fitted mattress protector that wants waterproof protection on top and a comfortable and soft cover that they can easily throw in the washing machine.

Waterproof Test

Most mattress protectors these days promise to stop fluids from spills or accidents getting onto your mattress. I always like to test them out and make sure they really are waterproof like they may claim.

The Helix protector has an especially soft polyester fabric on top but right beneath that is a backing layer of 100% polyurethane that should stop water from getting through to the mattress.

I initially poured 8 ounces of water on top of the Helix mattress protector. The water pooled immediately but eventually soaked into the protector to provide a true test. I left it for a couple hours, checking occasionally – and found no leaks or dampness.

Additional Considerations

Size and Noise: While the protector is designed with the 10” thick Helix mattress in mind, it actually fits mattresses up to 15” thick from my experience. This means that there may be some extra fabric around the sides of the bed for people using it with a mattress less than 15”, which could potentially be an issue.

Sometimes extra fabric can lead to looseness and “noise” from the rustling of the protector against the mattress, so that is definitely something to note.

I tested the King size protector on a 12-inch mattress, meaning there was potential for excess fabric. I had a little bit of excess fabric but I was able to tuck it in under the bed with the elastic grip of the protector.

There was a little bit of movement but for the most part, the mattress protector stayed snugly on my mattress and could barely be felt under my Bamboo Sheets Shop sheets.

Breathability: The protector did a good job of breathing well from my general experience. I never woke up hot or uncomfortable while I tested the protector.

The Helix mattress protector is soft, waterproof and compatible with any mattress up to 15" thick. It fits well and can hardly be felt underneath. May not be affordable at all budget levels.

Price and Value

On Helix’s website, the protector ranges from $75 – $99. Mattress protectors tend to vary greatly in price since there are so many types and materials that can be used. At this price the Helix protector might not fit every budget but it’s not the most expensive protector I’ve seen on the market.

The Helix mattress protector is a solid option. It’s thick, durable, easy to clean and goes onto most mattresses with ease.

If anyone is looking for a protector to complement the Helix mattress, this would be an excellent option. Other mattresses will work well with the bed and the top knit fabric makes it feel invisible underneath your sheets.
