The best memory foam mattress topper is a quick and budget-friendly way to add that body-cradling feel to any mattress. Not only can a memory foam mattress topper soften an uncomfortable bed or refresh an older mattress, but it can also prolong the lifespan of even the best mattresses on the market.

Fortunately, our panel of sleep experts have put together this guide full of the five best memory foam mattress toppers. We've slept on, tested, and reviewed every single memory foam bed topper on this list ourselves, and we would confidently recommend any of them. Plus, you can find all five in this year's official best mattress toppers guide

Our top pick for best memory foam topper is the Tempur-Pedic Tempur-Adapt Mattress topper, a premium bed topper that adds cloud-like pressure relief to any bed. However, it's not the only mattress topper we recommend. Here are our recommendations for the best memory foam mattress toppers at a range of budgets, with some permanently on sale. Plus, you can expect to find some bigger price drops thanks to the upcoming Labor Day mattress sales.

The Tempur-Pedic topper is the kind of premium option you'd expect from the brand known for making some of the best luxury mattresses around. It's not cheap, but it is the most affordable way to inject some Tempur magic into your room. The plush memory foam (called 'Tempur Material') molds to the sleeper's shape, offering outstanding pressure relief and soothing cushioning. The softer feel is perfect for side sleepers and those looking to make their bed a little more plush, but stomach and some back sleepers might find it unsupportive.

Tempur Material is meant to regulate temperature, but our main tester woke up slightly warm some mornings (we had the same issue in our Tempur-Adapt mattress review). If you are a chronically hot sleeper, check out the Saatva (#4) instead, or if you're set on Tempur, consider adding the specialist cooling cover upgrade. Either way, you'll be able to remove the cover and pop it into the washing machine for easy cleaning.

Customer feedback for the Tempur-Pedic Tempur-Adapt mattress topper is overwhelmingly positive, with nearly three-quarters of its 5,400+ verified user reviews earning a perfect 5 stars. Fans of the Tempur-Adapt topper credit it for easing (or eliminating) their aches and pains, and those who upgraded to the cooling version found it effective in keeping them comfortably dry. Those who didn't get on well with this topper said it's too soft, and some claim it slides around on their bed. (Ours did not slide at all, thanks to its corner elastic straps.)

One disappointing thing given the higher price, is that this topper doesn't come with a trial period, and it's also the only model on this list (as far as we can see) that doesn't allow returns unless there's a fault. As a result, it's a bit of a risk if you're not already familiar with how Tempur Material feels. Our top tip is to keep an eye out for a deal – there are semi-regular Tempur-Pedic mattress sales that knock 40% off MSRP on this topper, which makes it a lot more affordable.

The best memory foam mattress for making firm beds soft

Specifications

Depth: 3"
Straps: None
Cover: Not machine washable
Price bracket: Upper-mid
Trial: 30 nights
Warranty: 5 year limited

Reasons to buy

+
Good temperature regulation
+
Cloud-like comfort
+
Great for side sleepers

Reasons to avoid

-
Perhaps too soft for back sleepers
-
Cover isn't machine-washable
-
No straps

The Casper Comfy Mattress Topper is the best memory foam mattress topper overall. This three-inch thick topper is made up of two different mattress foams; at the top is a plush panel of memory foam, and below that is a layer of base foam. Both layers are wrapped in a smart grey knit cover.

We were extremely impressed with this topper when we tested it out. The sleep surface cradles your body and offers excellent pressure relief, but it's still responsive enough that you can still move around easily. This plush cushioning is perfect for side sleepers, who need softness around their hips and shoulders in this position. Both layers of foam are perforated to help disperse heat, and our tester found the temperature regulation very effective here. 

Any downsides to be aware of? While our main tester found this topper comfortable in all sleep positions, their preference is for a softer bed, and in general we'd recommend something slightly firmer for those who like to sleep on their stomach or back, or heavier individuals. It's also slightly annoying that while the cover is removable, Casper doesn't recommend machine washing it – officially, it's spot clean only. The lack of straps mean you're relying on gravity to anchor it to your bed, too (we'd recommend adding a mattress protector or fitted sheet to help keep it in place). 

If you're not sure about investing, be aware this topper comes with a 30-night sleep trial you can use to make sure it's right for you. It's not the longest trial on our list, but some toppers don't come with a trial at all. Price-wise, this sits in the upper mid-range market and offers excellent build quality and value for what you're paying. If you have cash to splash and want something more luxurious, definitely check out the Tempur-Pedic option (#1), or for something a bit cheaper, with a cover that is machine washable, consider the Viscosoft option at #5. Or hold out for a Casper deal or sale to take the price down.

If you're on a tight budget, and just want to add to softness to a too-firm mattress, take a look at this Lucid Gel Memory Foam option. At 2,3, or 4 inches tall, this topper is thick enough to mask all manner of lumps and bumps beneath, and very squishy. It's best suited to side sleepers seeking extra cushioning and pressure relief along their shoulders and knees. Back and front sleepers are likely to find this topper uncomfortable and unsupportive. We'd also advise steering clear if you have any sort of lower back pain (pick something that's more supportive – the Viscosoft #5 would be ideal, although that is a fair bit pricier). 

The Lucid topper is perforated and infused with cooling gel to stop it from too much trapping body heat (an issue with cheap memory foam). Our testers found it did a decent job at temperature regulation, although if you struggle with overheating at night, this might not work for you. Aside from those cooling additions, the design is about as basic as it comes – it's just a big old chunk of foam, with no cover and no straps to keep it in place (there is the option to add a cover, but this version was unavailable last time we checked). 

The Lucid Gel Memory Foam Mattress Topper has a 4.4 average over ~30k reviews on Amazon (June 2023), although note that includes reviews of the version with the optional extra cover. Fans of this topper say it's like sleeping on a cloud, with many sleepers claiming it has helped reduce some of their aches and pains. However, some customers say it's too soft and they felt like they sank too much into it.

There are also question marks around its durability. Lucid includes a 3-year warranty but some Amazon reviews suggest it might not last that long with regular use. Alternatively, for ultra-basic options, head to our best cheap mattress toppers under $50 guide.

Reviewers for our Lucid Gel Memory Foam Mattress Topper review were impressed with this budget topper's gel-infused foam and ventilated design that added some great temperature regulation. It comes in three different height options (2", 3", or 4") and is best for side sleepers in need of cushioning pressure relief. Right now there's a flash summer sale at Lucid which knocks up to 30% off, bringing a queen 3" topper to $54.99 (was $99.99).

Trial: 180 nights
Warranty: 1 year limited

Reasons to buy

+

Reasons to avoid

Priciest option on our list

Cover is spot-treat only

The best memory foam mattress topper for hot sleepers is the Saatva Graphite topper. Memory foam can have a habit of trapping body heat, which means it's not always the best choice for those who naturally run warm. However, this graphite-infused topper is designed with temperature regulation in mind, and delivers on those promises. During our review period, our tester slept quite comfortably on this topper regardless of what the weather was doing, and found it offered an experience on par with some of the best cooling mattresses they'd tested. The organic cotton cover is naturally breathable, although we do wish it was machine-washable rather than spot-clean only. 

The sleep feel is medium (around a 6/10 in terms of firmness) and while we found it comfortable in all sleep positions, we felt most at ease resting on our backs – especially our primary tester, who was dealing with a lower back injury at the time.

This is the priciest topper on our list, and for that higher price you can expect excellent build quality and materials (Saatva also makes our top-rated mattress – the Saatva Classic). If you like the brand but want something more affordable, check out our Saatva Memory Foam topper review – this one is less than half the price, although also much thinner at 1.5". Or keep your fingers crossed for a Saatva mattress sale to take the price down. 

Unlike the similarly priced Tempur-Pedic (#1), it comes with a generous sleep trial you can use to make sure it's the right choice for you. It's not all great news, though, because the warranty is bafflingly short. Nevertheless, if having a cool place to sleep is a priority (and you're willing to spend a little extra to get there), the Saatva Graphite could well be worth the investment.

Not much memory foam 'hug'

If you have a too-soft mattress, the best memory foam mattress topper for you comes from Viscosoft. This medium-firm topper contains two different layers of foam, and offers some subtle cradling on the joints rather than a full memory foam 'hug' sensation. This stable cushioning may be just what you're looking for if you're a back sleeper (or even a front sleeper) who needs support along the lumbar to keep everything properly aligned. During our testing period we were impressed with how this topper distributed our reviewer's body weight evenly. 

As the name suggests, the Viscosoft Active Cooling Mattress Topper is also designed to relieve hot sleepers. Our testers were pretty impressed with this topper's temperature regulation properties. While we had no issues with overheating, for maximum cooling consider shelling out for the Saatva at #4.  

Other customer reviews are equally enthusiastic about this topper's supportive sleep feel, although some found it look a little while to adjust to it. Some customers claim that it's resolved their lower back or hip pain. Reactions are mixed when it comes to this topper's cooling properties, however.

At full MSRP this Viscosoft topper is pricey, but there seems to be a permanent discount that makes it more affordable than the MSRP would suggest. A 5-year warranty applies. And if you're keen on coordinating your topper to match the aesthetic of your room, this is the only topper that's also available in a black colorway.

How to choose the best memory foam mattress topper

Why you can trust Tom's Guide Our writers and editors spend hours analyzing and reviewing products, services, and apps to help find what's best for you. Find out more about how we test, analyze, and rate.

When it comes to choosing the best memory foam mattress topper you’ll want to pay mind to the following...

Firmness level

Depending on what you’re looking to address with a mattress topper, you’ll want to pick either a plush or firm one. The taller the bed topper, the softer it'll be.

A soft, plush topper is great for those who want to sink into bed at night and be cradled in support from all sides. Especially ideal for side sleepers, these types of mattress toppers aid in more pressure relief compared to firmer toppers. 

However, for those who need more support during the night – particularly back and stomach sleepers – a firm topper will provide a more sturdy surface to promote spinal alignment. 

Temperature regulation

If you’re a hot sleeper, you’ll want to choose a memory foam mattress topper that's ventilated to increase airflow. You can also opt for a foam topper that's infused with cooling elements to draw away heat – for instance, graphite, gel, or copper. Some memory foam mattress toppers include covers made from breathable materials to aid in cooling.

Cost

Purchasing a mattress topper is always going to be a more economical alternative to buying a new mattress outright. However, prices vary among bed toppers. For a short-term solution that'll tide you over until you're ready to buy a new mattress in a year or two, a budget-priced topper should suit just fine.

On the other hand, if you're hoping for a longer-term fix – for instance, you're a student who doesn't want to spend four years on an uncomfortable dorm cot – spending a little extra will go a long way in enjoying continuous nights of restful, quality sleep. (If you're wondering whether it's worth a proper upgrade, our ranking of the best mattresses for college students has plenty of budget-friendly picks.)

What's the difference between foam and memory foam mattress toppers?

At first glance, you may think that all foam toppers are memory foam but that’s not the case — even though they may look similar. 

Unlike traditional foam, memory foam has more density and viscosity. It creates a ‘hug-like’ feel that cradles the body at every point for ideal pressure relief and comfort that traditional foam doesn’t do in the same way. Additionally, memory foam springs back into shape a lot quicker than regular foam. 

Memory foam is typically more expensive than its standard foam counterparts because of these properties, but there are affordable options available at many online retailers to browse and shop. You'll find them discounted during year-long mattress sales
