Beautyrest Harmony Lux Mattress Review for 2024

The Beautyrest Harmony Lux is not your run-of-the-mill innerspring mattress. It has the option of a plush pillow top, making this an excellent choice for those who like more softness and pressure relief, and while it may have the traditional component of an innerspring, Beautyrest has designed this mattress with the latest innovations in support, comfort, and cooling.

This mattress comes in a couple of varieties: The Beautyrest Harmony Lux Carbon and the Beautyrest Harmony Lux Diamond. You are also able to choose your desired firmness and whether or not to add a pillow top. In this in-depth review Beautyrest mattress review, we’ll be focusing on the Carbon model with a medium firmness and pillow top.

Who We Recommend The Beautyrest Harmony Lux For:

  • Hot sleepers – The Beautyrest Harmony Lux is made with hot sleepers in mind. It starts with the cover, which is cool to the touch. The pillow top layer also includes something called RightTemp foam, which helps keep the top of the mattress cool.
  • Back and side sleepers – The medium firm mattress with the pillow top that we tested should be a great combination of softness and support for most side sleepers and back sleepers who like some cushion in their mattress.
  • Fans of innerspring mattresses – With the added pillow top, this innerspring mattress feels supportive and bouncy so you don’t get that “in” the bed feeling while still being plush and pressure-relieving.

Who We Don’t Recommend The Beautyrest Harmony Lux For:

  • People who prefer memory foam beds – Mattresses with memory foam are slow to respond and conform well to the shape of the sleeper’s body. As an innerspring mattress, this one doesn’t have that same “sinking in” feeling, but with the added pillow top, it does still provide great pressure relief.
  • Stomach sleepers – Stomach sleepers need a firm mattress so that their hips don’t sink and throw the spine out of alignment. The mattress we tested includes a pillow top, which could make it too soft for stomach sleepers. Therefore, these sleepers might do better with the Extra Firm model or the Medium without the pillow top.

First Impressions: Firmness & Feel

Firmness Scale: 5.5/10

Please remember that firmness is a subjective characteristic and your shape will dictate how you experience a bed. A heavier person whose weight can more easily push through softer comfort and support layers may experience a bed as softer than a lightweight person. The way you are shaped could also play a role here. Consider your weight, shape, and size when evaluating firmness scores.

Mattress Firmness Level 5.5

The Medium model for the Beautyrest Harmony Lux Carbon rates at a 5.5 out of 10 on our mattress firmness scale. To put this into perspective, we consider a medium firmness to be between a 5 and 7, so this bed falls within that range. Medium mattresses are more popular because they are accommodating for more sleepers.

Also, keep in mind that we are reviewing the mattress that also has the pillow top addition. Without the pillow top, the mattress would likely have felt firmer as the pillow top is quite plush.

How Does It Feel?

The Harmony Lux is delivered full-size so there’s no waiting period common to online mattresses delivered in smaller boxes. It can be dressed immediately.

When you lie down on the mattress, the first thing you’ll notice is the plushness of the pillow top. The bed contains some memory foam, so there is some nice contouring and sinkage, but it is still an innerspring mattress. This makes it feel responsive while still delivering cushioning for joints.

What We Like About the Harmony Lux Carbon

  • The cover – The cover is made with Seaqual™ sustainable fabric, which is created from recycled plastic waste and is incredibly soft. This is a great eco-friendly cover.
  • It’s cooling – Both the InfiniCool™ Lux foam used in the pillow top and the pocketed coils in the support layer make this mattress a great option for hot sleepers.
  • It has great motion isolation – Despite having coils, the mattress provides great motion isolation. This makes it an ideal option for sensitive sleepers who share a bed.

Our Harmony Lux Carbon Complaints

  • It may be too soft for some – People who prefer an exceptionally firm mattress could find this one too soft. If you already know you prefer a firmer mattress, then you might be better off with the Extra Firm version.
  • It’s not great for all sleep positions – Stomach sleepers and some heavier back sleepers will need a firmer mattress. These sleepers should also not add the pillow top option.

Testing the Harmony Lux Carbon: How it Performed

When we tested the Harmony Lux Carbon Mattress, we looked at specific features like cooling, motion isolation, bounce, and edge support. We also tested the bed in different sleeping positions, assessing how well it does at providing support and pressure relief in each posture.

Sleeping Positions for Different Body Types

According to Beautyrest, their Harmony Lux Carbon mattress is designed to comfortably support up to 300 pounds per side of the mattress or 600 pounds total.

Side Sleepers

  • Lightweight Sleepers – Lightweight side sleepers should feel comfortably supported by the Medium model with the pillow top. If you are very petite or know you need an even softer bed, you can choose the Plush version instead.
  • Average Weight Sleepers – Most average-weight sleepers should experience pressure relief on their hips and shoulders with this mattress, and we recommend they get the added pillow top.
  • Heavyweight Sleepers – Many heavier side sleepers should feel comfortable on this bed, but if the Medium model with the pillow top causes you to sink in too much, you can choose to not add the pillow top or opt for the Extra Firm version with the pillow top.

Back Sleepers

  • Lightweight Sleepers – Lightweight back sleepers should feel a good balance of pressure relief and comfort with this bed. The pillow top should contour the back while still feeling supportive.
  • Average Weight Sleepers – Most average-weight back sleepers should feel supported with this bed. They’ll sink in enough to reap the benefits of the pillow top comfort layer and the innerspring support layer.
  • Heavyweight Sleepers – Many heavyweight back sleepers should appreciate this bed, though it might be too soft for those over 300 pounds. In this case, you can opt for the firmest model or a bed designed for heavier sleepers.

Stomach Sleepers

  • Lightweight Sleepers – Some lightweight stomach sleepers might get the support they need with this bed, but for many, the pillow top will make it too soft.
  • Average Weight Sleepers – Average-weight stomach sleepers won’t get the support they need with this medium-firm mattress plus the pillow top. Strict stomach sleepers should opt out of adding on the pillow top.
  • Heavyweight Sleepers – Heavier-weight stomach sleepers should either not select the pillow top option or choose the Extra Firm version of this mattress, as the medium-firm with the pillow top will be far too soft and not supportive enough.

Pressure Relief & Pain

Pressure relief is important because it can help alleviate tension in the muscles and joints when you lie down to sleep.

The Beautyrest Harmony Lux Carbon, with the added pillow top, provides excellent pressure relief overall, without feeling ‘stuck’ in the mattress, which can happen with some memory foam mattresses. Instead, it has a quicker response to pressure, so you should be able to move around and get off the bed easily.

Back Pain – The Harmony Lux Carbon is an excellent choice for those with back pain. It will allow the weight to be evenly distributed across your back, removing the pressure from the lower back. If you prefer a softer, more contouring feeling mattress, the pillow top is a must. If you prefer something more firm with less cushioning, you can go without the pillow top.
Hip Pain – This mattress is wonderful for relieving hip pain for side sleepers since it provides the cushion and contouring this area will need. If you sleep on your stomach, however, it is soft enough that it might exacerbate hip pain by allowing them to sink too far into the mattress.
Shoulder Pain – The soft comfort foams in the pillow top make the Harmony Lux especially good for relieving shoulder pain for side sleepers who need extra cushioning in this position.

Support

The Harmony Lux Carbon has an advanced support system made up of T2 pocketed coils. T2 is Beautyrest’s exclusive coil design, which involves individually wrapping the coils in fabric and then surrounding them in a high-density foam.This combination makes this mattress incredibly supportive for most bodies and positions.

It’s also easy to customize the Harmony Lux for your individual support needs. You can choose between Plush, Medium, or Extra Firm, and you can choose to add on the pillow top or not. We found the Medium with the pillow top to be supportive while still comfortable, though very heavy people might need something firmer.

Motion Transfer

If you’re a sensitive sleeper and you share a bed, you’ll need a mattress that has very little motion transfer. Luckily the Harmony Lux has excellent motion isolation, meaning you should feel minimal movement when someone else is moving on the other side of the bed.

Oftentimes, innerspring mattresses are bouncy and responsive but don’t isolate motion well. However, this mattress has better-than-expected motion control because of its unique construction – the T2 coils that are surrounded by foam.

Temperature Regulation / Cooling

The Beautyrest Harmony Lux mattress was designed with cooling in mind. It starts with the cover, which includes Beautyrest’s proprietary InfiniCool Lux technology. Beneath that, the pillow top layer contains RightTemp Wave foam, a soft foam made with conductive carbon fibers to increase the mattress’s breathability. Underneath that layer are the pocketed coils, which allow air to pass through the mattress.

Based on its multiple cooling features, we think this mattress is an excellent choice for those who sleep hot.

Performance for Couples

This mattress is excellent for couples. As mentioned, it is great at isolating motion, meaning the bed shouldn’t move too much when your partner does; but it also still has a good amount of bounce, which some couples prefer for intimacy. Plus, its cooling qualities and high-quality edge support make the Harmony Lux a great mattress for couples.

Preference-based Features

Multiple Firmness Options

Beautyrest allows sleepers to choose their perfect firmness level by providing three options: Plush, Medium, or Extra Firm.

Optional Pillow Top

For an added 400 dollars, you can choose to include a plush pillow top comfort layer on your Beautyrest Harmony Lux.

Exceptional Edge Support

This mattress includes coils that are firmer along the edges of the bed, giving it excellent edge support. This means you’ll be able to use the entire surface of the bed and won’t have to worry about sagging.

Free White Glove Delivery

All Beautyrest mattresses include free white glove delivery. After you’ve completed your order, you’ll be contacted by the company to select a delivery day that works well for you. When your mattress is delivered, they’ll set it up, remove your old mattress, and take away any packaging materials – all free of charge.

Environmental Initiative

The cover is made with Seaqual™, an eco-friendly fabric created from recycled plastic waste. The Seaqual™ team gets these materials from polluted seabeds and uses them to create sustainable, soft, and durable fabrics.

Construction: What’s Inside the Beautyrest Harmony Lux Carbon?

The Harmony Lux Carbon mattress from Beautyrest is an innerspring mattress with a soft foam top layer. Without the additional pillow top, the mattress measures 13.5 inches tall, but with the pillow top, it measures 15.75 inches tall.

We looked at the Harmony Lux Carbon with the pillow top, and below we’ll go over each layer of this mattress.

  • The cover of the mattress features Seaqual™, an eco-friendly fabric that is made from recycled plastic waste found in the ocean. The cover is also quilted to soft InfiniCool™ Lux foam, making the surface of the Harmong Lux Carbon incredibly soft, cushioning, and cooling.
  • Going deeper, the pillow top comfort layer is made from a combination of foams. The first layer of the pillow top is the super soft RightTemp™ Wave Foam. It is pressure-relieving as well as cooling. Below that is a layer of gel memory foam, which contours nicely to the body, and below that, one more layer of medium comfort foam.
  • Then, there is the support layer. The Harmony Lux’s support layer is made up of a pocketed coil technology exclusive to Beautyrest. Called “T2 pocketed coils,” they are individually wrapped in fabric for better motion isolation and then surrounded by high-density poly foam around the edges of the bed. This allows for great edge support.

Unboxing & Off-Gassing

Unlike many beds you can order online, this one is not delivered in a box, so there is no unboxing or off-gassing period. Instead, the Beautyrest Harmony Lux Carbon comes with free white glove delivery. This means that with the cost of this mattress, you can arrange for it to be delivered and set up, and for your old mattress and any packaging to be removed. You can then dress the bed immediately.

Certifications

  • CertiPUR-US® certified – The foams in this bed are CertiPUR-US® certified. CertiPUR-US® is a third-party program that ensures the foams meet rigorous health and safety standards. This means they don’t contain harmful substances like ozone depleters, PBDEs, heavy metals, formaldehyde, and phthalates. They should also have low volatile organic compound (VOC) emissions.

Coupons, Trials, Warranties, and Shipping

  • Shipping – Shipping is free within the United States.
  • White-Glove Delivery – Professional installation is included with the price and will be arranged at your time of purchase.
  • Trial – You can keep this product for 100 nights to make sure it’s your dream mattress, and if it isn’t, the company will refund your money.
  • Warranty – This Beautyrest mattress comes with a 10-year warranty deal.

Frequently Asked Questions

Who makes Harmony Lux mattresses?

Beautyrest makes Harmony Lux mattresses, and they are part of Serta Simmons Bedding. This is one of the oldest bedding manufacturers in the United States, though Beautyrest only recently started making their mattresses available online in 2019.

Does the Beautyrest Harmony mattress need a box spring?

Beautyrest mattresses will work with most frames, foundations, or adjustable bases. The company recommends a box spring, another solid surface, or a bed frame with slats that are no more than two inches apart to avoid sagging and damaging the mattress.

How many coils does the Beautyrest Harmony Lux have?

The Beautyrest Harmony Lux has 465 coils.

Can you flip the Beautyrest Harmony Lux mattress?

You can’t flip the Beautyrest Harmony Lux, as it is built with a comfort layer on top and a harder base layer on the bottom. You can, however, rotate the mattress 180 degrees every six months to avoid uneven wearing.

Overall Summary

The Harmony Lux Carbon is an innerspring mattress with quality materials and advanced cooling and support technology. The medium-firm mattress with the added pillow top should be especially suitable for side sleepers, couples, and back sleepers who prefer a softer, more contouring feel.

Side Sleepers

5/5

Side sleepers need a softer mattress to relieve pressure from the shoulder and hips. The medium-firm Harmony Lux Carbon with the pillow top is a great combination for most side sleepers. If you are particularly petite or love an extra soft mattress, you could select the Plush mattress, with or without the pillow top, but we wouldn’t recommend going firmer.

Back Sleepers

4/5

Lightweight and average-weight back sleepers who prefer a bed with more cushioning will appreciate the Medium model with the pillow top. For those who need something firmer, though, we recommend selecting the Extra Firm option with the pillow top or the MMedium without the added pillow top.

Stomach Sleepers

2/5

Stomach sleepers must watch out for spine alignment because the hips, which typically carry the most weight, tend to dip in this position. Unless you are very lightweight and won’t sink into this mattress, we don’t recommend the added pillow top with the medium-firm mattress. Instead, order your mattress without the pillow top or get the Extra Firm.

Combination Sleepers

4/5

The balance of pressure relief and support in this mattress makes it a good choice for combination sleepers. The springs provide enough support for most back sleepers, plus they are bouncy enough to make changing positions easier, and the pillow top makes it soft enough to sleep on your side. The only position it doesn’t do well with, though, is stomach sleeping.

Couples

5/5

This mattress delivers a rare combination of motion isolation, bounce, and edge support, making it a fantastic choice for couples. It also has advanced cooling technology throughout the mattress and the pillow top comfort layer, so you and your partner shouldn’t get too warm at night.

Heavy Sleepers

3/5

This is a great mattress for heavier side sleepers and some back sleepers who prefer a soft-feeling mattress. For those who need more firmness and support, though, we recommend opting out of the pillow top or choosing the Extra Firm model to keep your spine supported and in proper alignment.

Lightweight Sleepers

4/5

Lightweight sleepers should be comfortable on this bed while on their side or back. If you’re under 130 pounds and choose the Carbon, we recommend adding on the pillow top, with the exception of stomach sleepers, who should opt out of the pillow top on the Medium.

Average Weight Sleepers

4/5

Unless you prefer a firm mattress, the Medium Harmony Lux Carbon with the added pillow top should be a good fit for most average-weight sleepers. This will be especially true for average-weight side and back sleepers. If you sleep on your stomach or prefer something firm, don’t add on the plush pillow top.


Overall Value

5/5

The Harmony Lux Carbon is comparable in price to its competitors and comes with a good reputation and a trusted brand name. It is less expensive than other Beautyrest models but still includes advanced cooling, support, and pressure relief technology. This, plus their free white glove delivery and commitment to sustainable materials gives it a great overall value.

Our Verdict

Beautyrest may be newer to online sales, but this established brand has been around since the 1920s. These years of experience are clear in the Beautyrest Harmony Lux Carbon. It is made from quality materials, it is durable, and it is comfortable as well as supportive.

We love that there are multiple firmness options, making it suitable for most sleepers. The Medium-firm mattress with the pillow top will be especially good for side sleepers, lightweight and average-weight back sleepers, hot sleepers, and couples.

Stomach sleepers or those who want a firmer mattress should avoid adding on the pillow top or select the Extra Firm version when ordering.
