Big Fig Vs Helix Plus Overview

Big Fig is one of the best mattresses for heavy sleepers. It’s built with durable coils and high density foam so it should last longer than most mattresses. It also comes with an 18-slat base to keep the bed supported. Due to its sturdy construction, this mattress and frame can hold up to 2,000lbs.

Helix makes it easy for all sleepers to find their perfect mattress. The Helix Plus model means heavier sleepers should get the support they require. With its tall, supportive coils and high-density foam, this mattress can stand up against heavier weights. Plus, it’s made with durable, quality materials so it won’t sag after only a few years of use.

Who Should Get The Big Fig

  • Heavier sleepers in the 300-500lb range

Who Should Get The Helix Plus

Firmness and Feel Differences

To decide which mattress is right for you, we need to look at the firmness and feel of these two mattresses.

How Firm Are The Big Fig and Helix Plus Mattresses?

Here at Mattress Clarity, we rank our mattresses on a firmness scale of 1-10, with 6.5 being the industry average or medium firm. The Big Fig’s firmness level came in at 8/10. This makes the Big Fig firmer than the industry average.

Helix Plus is also firmer than the industry average at a 7/10. However, the Big Fig is the firmer of the two without question.

Sleeping On the Big Fig and Helix Plus Mattresses

Since the Big Fig is such a firm mattress, it will be a great choice for heavier stomach sleepers. Heavier stomach sleepers should feel well supported throughout the night. However, back sleepers might not feel their hips sink into the mattress completely. Side sleepers also might feel pressure on their hips and shoulders.

Big Fig - Side Sleeping

On the other hand, the Helix Plus is a great option for back sleepers. The top foam layers press into the lumbar area so heavier back sleepers shouldn’t feel any lower back pain. It should also provide some good contouring and help promote the correct spinal alignment. Heavier side sleepers might feel some pressure on their side and hips, but not as much as on the Big Fig. Stomach sleepers should feel well supported on this mattress.

Helix PLUS Mattress - Back Sleeping

What Do The Big Fig and Helix Plus Mattresses Feel Like?

Both mattresses have a balanced, hybrid feel, though their top layers do make them feel a bit different. The Big Fig’s quilted polyfoam makes it as fluffy as a pillow top. The Big Fig also is a bouncier mattress.

The Helix Plus has a memory foam feel because it’s top layers are made of soft memory foam. You’ll really sink into this mattress and find it contours around your body.

Average Weight Sleepers – 130lbs – 230lbs

Average weight sleepers probably won’t feel comfortable on either of these mattresses because they will both be too firm. However, average weight stomach sleepers closer to 230lbs might find good support on the Big Fig if they like firmer mattresses. This mattress will be too firm for average weight side or back sleepers.

Average weight side sleepers close to 230lbs might find the Helix Plus to be supportive, but might develop pain in their pressure points over time. For average weight back and stomach sleepers, this mattress won’t give them the support they need.

Heavyweight Sleepers – Over 230lbs

The Big Fig is a great choice for heavier stomach sleepers. Stomach sleepers with bigger figures should feel well supported throughout the night. Heavier side sleepers might not feel as supported. Their hips could sink in and they could feel pressure on their shoulders and hips. Heavier side sleepers over 300lbs should find good pressure relief from the Big Fig. Heavier back sleepers might feel their back arch too much because their hips won’t sink in. Those weighing over 300lbs might sink in enough to make this a good option for back sleeping.

The Helix Plus is a great option for plus size sleepers who sleep on their back. The foam layers provide lumbar support which allow heavier back sleepers to feel supported. This mattress also provides good contouring for added relief. Heavier side sleepers could feel some pressure on this mattress. They could still feel some near their shoulders and hips, though not as much as on the Big Fig. This mattress should provide great support for heavier stomach sleepers.

Lightweight Sleepers – Under 130lbs

Lightweight sleepers will find the Big Fig feels too firm. It’s possible some lightweight stomach sleepers may find the comfort and support they need, but it’s not the best choice for people with smaller frames.

It will be a similar story with the Helix Plus. This mattress is too firm for most lightweight side, stomach, and back sleepers as well.

Mattress Construction Differences

The Big Fig and Helix Plus have some distinct construction differences you’ll want to consider when purchasing your new bed.


The cover of the Big Fig is quilted with 1” of ThermoGel foam. This cover adds additional cooling and pressure relief to the mattress.

The Helix Plus cover is made of ultra breathable tencel fabric. It allows air to circulate through the top, keeping you cool as you sleep.

Comfort Layers

The Big Fig has a ½ inch comfort layer made of gel-infused latex foam. This layer adds bounciness to the mattress, helps with airflow, and adds breathability. Below that, the Big Fig has three 1” layers of polyfoam. These layers add extra support and protect against sagging.

The Helix Plus has three comfort layers. The top comfort layer is an inch of high density gel memory foam. This layer gives the mattress a slow-moving memory feel and the gel infusions help you sleep cool. Below that is a layer of Helix Dynamic Foam. This bouncy, latex-like foam adds some responsiveness to the top of this mattress. Finally, it has a transition layer of firmer memory foam to add more support for heavyweight sleepers.

Helix PLUS - Construction And Layers

Support Layer

Underneath the comfort layers, Big Fig has 7” of individually wrapped coils. This coil layer is supportive, durable, and breathable. Underneath the coils is a 1.5” base of high-density polyfoam to add to the support system of the mattress.

Helix Plus’ base layer features tall coils that are individually wrapped and made to handle heavier weights. They are also firmer towards the edge to help provide more edge support for heavy people. Beneath the pocketed coils is a layer of Helix DuraDense foam which supports the entire mattress.

Mattress Height

Both the Big Fig and Helix Plus mattresses are 13” tall.

Big Fig and Helix Plus Performance Differences

Still deciding which should be your new mattress? Check out these performance differences to determine which is right for you.

Sleeping Hot or Cold

The Big Fig mattress has gel infusions in both the comfort layer and cover. The ThermoGel foam is designed to prevent hot sleepers from overheating and the coils should promote airflow.

The Helix Plus also has some impressive features to keep you sleeping cool. The tencel cover should promote airflow and the memory foam layers are infused with a cooling gel to keep you from overheating throughout the night.

Motion Transfer

The Big Fig does an excellent job isolating motion. The Big Fig’s multiple foam layers help with motion isolation and make this one of the best mattresses for couples who don’t want to be disturbed by one another during the night.

While the Helix PLUS does a good job of handling most motion transfer, it is not as good at motion isolation as the Big Fig. Couples may feel each other toss and turn on this mattress while they sleep.

Edge Support

The Big Fig has a foam encasement to help with edge support. Whether you’re sitting or lying near the edge of the bed, you should feel supported by this mattress.

Big Fig - Edge Support

The Helix PLUS has great edge support as well. The coils near the edge are firmer, providing added support around the edges.

The Big Fig will be the more durable mattress between the two. It has extremely durable foam and its coils will add some life to the mattress.

However, the Hexlic Plus is also quite durable. Because of its DuraDense foam, this mattress won’t sag for years to come.


As an online mattress, the Big Fig might have some off-gassing but it should dissipate in 24-48 hours.

Since the Helix Plus is also a bed-in-a-box, it might also have some off-gassing. However all off-gassing should dissipate within 48 hours.


While it’s possible the coils could create noise over time, we did not notice any noise when testing the Big Fig mattress.

While Helix Plus features coils, it’s not particularly noisy. However, the coils may begin to squeak over time.


If you’re looking for the best mattress for sex, you’ll want something bouncy and easy to move around on. Since the Big Fig is bouncy and responsive, it should be a good mattress for sex. Big Fig’s balance hybrid feel means it should be easy to move around on as well.

The Helix Plus will be a similar story. It’s a bouncy mattress, but because of its memory foam feel, it might not be as easy to move around on as the Big Fig.

Company Policies

Let’s look at the warranties, sleep trials, and return policies for these two mattresses.

Warranty Info

Big Fig has a 20-year warranty. It is also non-prorated so customers don’t have to pay the cost of repairs and replacements.

With a 100-night sleep trial, you have plenty of time to decide if Helix Plus is right for you.
