The Helix Plus is a spring and foam hybrid mattress designed to give heavier sleepers proper support and pressure relief throughout the night. Because it was designed with plus size sleepers in mind, it should also last longer than a traditional mattress. A queen size currently retails for $1,190 but there are discounts available here to make it an even better deal. In keeping with Helix’s philosophy of custom comfort, they also offer the option to buy a cover that is cool to the touch helping you fall asleep just a little bit faster.

Overview and Ordering the Helix Plus

The Helis Plus is available exclusively through the Helix website. It comes with a standard 100-night trial where you can return it for a full refund within 100 nights of using it, that includes free shipping to you and free returns. It also has a 10-year warranty. This mattress comes shipped in a box like the one below. 
When you open the box, you will find a nice little manual about the mattress.

It doesn’t take long for this mattress to come to life. The spring system is engaged immediately and the top layers of foam will take a few hours to fully expand but if needed you could sleep on this mattress within 3 or 4 hours. It will take a full day for it to fully expand though.

Here’s a quick video explaining some of the features of the Plus.

Below are the construction details as listed on the Helix website.

My Helix Pus Findings

I have reviewed other mattresses for plus size sleepers including the Big fig and Winkbed Plus. In comparison to these, I found the Plus to be a bit softer. I weigh about 200 lbs. so I may not qualify for a heavy sleeper but in comparison to the other mattresses, this did feel softer.

The picture below shows how much sink you get with a 14 lb.s bowling ball.

Here’s another shot of sinkage towards the edge of the mattress. The coil system in this mattress uses a heavier gauge coil around the perimeter for better edge support so you can use the entire mattress and sleep right up to the edge.

Here’s a look at the inside of the mattress so you can see how each layer responds.

This mattress has a removable cover that could be washed or switched out for the cooling cover. The, “Ultra-Cool Cover” is an extra $125.nightfall cover

Here’s what it looks like underneath the top cover. There’s another cover underneath this to provide more breathability so that you aren’t directly under the foam.

My Helix Plus Recommendation

If you are a heavier sleeper and are frustrated with the lack of options out there, the Helix Plus is a welcome addition. It provides a softer feel with great pressure relief without sacrificing durability. The construction is well thought out in that the coil system provides great cradling of your body. The ultra-dense foams will hold up well over time and won’t feel too firm because of the cushioning you get from the coils.

Overall if you are a heavy sleeper, over 250 lbs. and looking for a softer cozier mattress that is breathable and still offers great support, the Helix Plus an excellent choice.
