Best Memory Foam Mattresses on Amazon
Zinus Memory Foam 12 Inch Green Tea Mattress
Zinus is a brand that has been making mattresses for over 25 years, and they are easily one of the most popular brands you can purchase from on Amazon. The Zinus Memory Foam 12 Inch Green Tea Mattress is one of the most purchased of its kind on the website, so it’s no surprise that we’re including it on a pick for the best memory foam mattress on Amazon. In terms of comfort and support, this mattress is of medium firmness, making it suitable for most sleepers, especially back sleepers. The memory foam contours well and easily to the body without feeling overly restricting. This product also helps distribute the body’s weight in an even manner, so spinal alignment is healthy and aches or pains are curbed. Motion isolation on this mattress is impeccable. You or a partner can move around on one side without alerting the other at all.
This mattress is made up of four layers, constructed as follows:
The topmost comfort layer of this mattress is made up of a 3” thick slab of memory foam. It feels quite soft when you lie down on it and conforms well and easily to the body in a warm hug. It is also designed to minimize motion transfer.
This layer measures 2 inches thick and is made from comfort foam. It helps with more even weight distribution, preventing aches and pain come morning, and makes the mattress feel more comfortable in general.
It also has a quick response time and responds well to movements for better pressure point relief.
This layer is a 3.5” layer of high-density foam fitted with airflow technology. What this layer does is offer support to the upper layers while also working to remove heat from the body as you sleep.
That heat is regulated and ventilated through the mattress, eventually being removed from it, so the mattress doesn’t overheat.
The base layer of this mattress also measures 3.5 inches, like the layer above it. It is also made from high-density foam designed specifically for foundational support, and it also makes use of a similar airflow technology.
This means it helps regulate temperature in the same way the third layer does. This base layer also has point elasticity, meaning it helps keep the spine well aligned in a healthy way so you don’t experience pain in key areas.
The cover for this mattress is made from knitted jacquard, which is very breathable, so it stays cool and comfortable throughout the night. Its design is fairly simple, with a white color that has small details and patterns on it, and feels soft to the touch for better, cozier sleep.
Edge support, meanwhile, is above average – more than usually expected of a mattress of this make, but not entirely the best of the best, either. The mattress is also very quickly responsive and has some nice bounce, which we don’t often see in memory foam mattresses.
From the standpoint of temperature regulation, this mattress does rather well. Its bottom two foam layers really help to prevent the overheating issue so commonly associated with memory foam products.
But while they don’t sleep hot, they don’t sleep cool, either, so if you tend to sweat at night you may still feel warm when using this mattress.
Safety-wise, this mattress has a CertiPUR-US certification and has undergone rigorous testing to ensure a high-quality performance. This is helped by the green tea infusion, which gives the mattress a delightful, relaxing scent and promotes a hypoallergenic sleeping surface.
Unfortunately, there are some quality control issues with this brand, with some receiving incorrectly stored mattresses that smell of mildew. While Amazon does replace these, it can be quite a hassle to deal with.
The Zinus Memory Foam 12 Inch Green Tea Mattress comes in a lot of different sizes: Twin, Narrow Twin, Twin XL, Full, Short Queen, Queen, King and California King, to be precise.
The mattress does not have any trial period but returns are accepted within 30 days, though you may pay some fees for returning without a solid reason.
The mattress has a limited 10-year warranty and is extremely affordable and budget-friendly, and this on top of all of its features and raving reviews cements the Zinus Memory Foam 12 Inch Green Tea Mattress on this list.

Best Price Mattress 10-Inch Memory Foam Mattress
Best Price isn’t a particularly well-known brand, but as their name suggests, they are dedicated to providing low-cost products of all varieties. The Best Price Mattress 10-Inch Memory Foam Mattress is one of these products, and although Best Price is not an Amazon exclusive brand, this mattress, in particular, has many fans and satisfied purchasers. The Best Price Mattress 10-Inch Memory Foam Mattress is one of these products, and although Best Price is not an Amazon exclusive brand, this mattress, in particular, has many fans and satisfied purchasers. Comfort and support-wise, this mattress is on the softer side of medium and may feel too soft for some sleepers. This is due in large part to the foam used as its middle layer. It’s a great mattress for side sleepers and back sleepers, but stomach sleepers will likely not be able to enjoy this mattress.
This mattress is made up of three layers, constructed as follows:
This layer is 3 inches thick and made from charcoal-infused memory foam. It tenderly hugs sleepers, conforms to the body well and sinks in comfortably.
Meanwhile, the charcoal features give it antibacterial and hypoallergenic properties while aiding in temperature regulation to help keep the mattress’ surface cool for sleeping on.
This layer is designed for both comfort and support and is made up of 2 inches of super soft pressure relieving foam.
This layer is primarily responsible for the soft feeling of the mattress, and it carefully manages pressure points to relieve aches and pains in key areas. This makes it a great pick for side and back sleepers.
This simple, foundational layer is 5 inches of thick, high-density foam. It maintains the shape of the mattress, provides support to the two upper, softer layers, and helps to add to the overall durability of the mattress as a whole.
It also aids in weight distribution, contributing to the soft pressure relieving features of the middle layer above it.
The cover on this mattress is made from a polyester and jacquard blend. It is made to be extra comfortable and soft to the touch and is designed with intricate embossed patterns and details.
This mattress’ main design goal is to completely relieve all pressure points and distribute weight evenly, so you feel almost like you are sleeping on a cloud. As such, it’s a great mattress for those with back, neck, shoulder, or joint pain of any kind. The mattress’ response time is on the slower side, so it gently cradles the body very thoroughly. If you don’t like slow-reaction memory foams and the “stuck” feeling they have, you may not like this one.
It is in other areas that this mattress starts to veer towards average. The mattress has good motion isolation and passable edge support. There are no particular features implemented in order to strengthen either of these features.
Meanwhile, the temperature regulating features that the mattress does have are not sufficient to fully keep the mattress cool.
As such, the mattress sleeps anywhere from warm to comfortably neutral, which means it may not be the best pick for those who tend to sweat at night.
This mattress does not have a strong off-gassing smell, likely due in part to its CertiPUR-US certifications.
It is made in China without volatile organic compounds and in a relatively environmentally friendly way. The ActivFresh charcoal infusion used is also made in an all-natural manner and is free from harmful chemicals.
The Best Price Mattress 10-Inch Memory Foam Mattress comes in Twin, Twin XL, Full, Queen, King and California King sizes, as well as a selection of different thicknesses with varying layer compositions.
It has a limited 10-year warranty period – impressive for a mattress of this price point – and Amazon’s standard 30-day return policy.
Although it is far from the most luxurious or “perfect” mattress out there, it’s a great option for those on a tight budget who still want great quality – and that’s why it’s one of our picks for the best memory foam mattress on Amazon.

Features to look for
Most good memory foam mattresses aren’t just made from memory foam. Instead, they have layers that provide a variety of benefits, helping to create a more comfortable and supportive product overall.
The most common form of construction for a memory foam mattress is a three-layer design.
The topmost layer is usually a comfort layer – which typically consists of the actual memory foam – that is designed to feel soft and cozy for sleepers.
The middle layer is typically a support layer of a stronger foam that helps to provide the body with healthy support, spinal alignment, and uplifting force so the mattress does not sink in too far. The final layer is known as the base layer.
It basically keeps the entire mattress together, promoting better durability, retaining the mattresses shape, and serving as a strong foundation for you to sleep on. Most mattresses also come with a top cover that encases all the aforementioned foam layers.
Do take note that while this is the most common form of mattress construction, it is not rare to see mattresses that have wildly different makes and structures.
Overall, you should take note of a memory foam mattress’ construction because it gives you a good idea of how the mattress will feel, what features it has, and whether it’s suited to you or not.
Memory foam mattresses may also come in hybrid form, meaning they’re a mixture of memory foam and some other variety of mattress. The two memory foam hybrids you will likely encounter are latex and innerspring hybrids.
Innerspring is a more traditional variety of mattress and is made up of coils within the mattress’ foam layers, and typically, innerspring offers a good balance to memory foam, with each material making up for the other’s weakness.
Meanwhile, latex hybrids aid memory foam it areas it lacks strength, such as in temperature regulation and response time.
Comfort, Firmness, and Support
While they don’t sound like they’re all the same thing, these three factors tie in very tightly together.
The perfect memory foam mattress balances all three of these characteristics well, though the amount of comfort and firmness you desire is mainly up to preference and the amount of support you should opt for depends on your weight and sleeping position.
Comfort typically refers to firmness or softness, although it does encompass other factors like heat retention and cover material. Still, you will mainly want to focus on how soft or firm a mattress is as a priority when it comes to comfort.
Whether you prefer to sink in a little into your mattress or you like a mattress that is unyielding, most manufacturers and brands will tell you where each mattress falls on the scale.
So how does support intertwine with comfort? In general, the more supportive a mattress is, the firmer it feels.
If you are a heavier individual, you will likely need a more supportive mattress in order to avoid the layers sinking in too far. Too much sinkage can lead to spinal misalignment and cause aches and pain in the joints and pressure points.
The kind of support you need also depends on the position you sleep in. Side sleepers need softer mattresses because their weight is pooled on smaller points while stomach sleepers need firmer mattresses for better spinal alignment.
Meanwhile, back sleepers should go for medium firm mattresses.
Comfort and support are arguably the two most important factors in choosing a mattress.
When you are purchasing online, you don’t get to test them out yourself before buying them, which is why you should be very aware of what mattress will work best for you before purchasing.
If you share your bed with a partner, and especially if one of you is a light sleeper, you will want to opt for a memory foam mattress with good motion isolation.
This feature is one that dictates the mattresses response to movement and pressure. A mattress with good motion isolation will allow one person to move freely on their side of the bed without waking the other.
Motion isolation has to do with the construction of a mattress, from the density of the foam to the types of layers used. Be sure to thoroughly read the specifications of a mattress’ make before purchasing if motion isolation is an important characteristic for you.
Many memory foam mattresses – being made of, well, foam – have a tendency to be a little less hardy along their sides.
While edge support is far from the most important features of a memory foam mattress, it’s still not a bad idea to look out for one that won’t sink in the corners or give in when weight is placed on its edges.
Plus-sized individuals and pregnant women may require edge support to prevent wear and tear to the sides of the mattress and also to prevent accidental falling when sitting too far on a corner.
If you often end up sleeping on the far sides of a mattress when you move around at night, you should also look for a mattress with good edge support. Ideally, a memory foam mattress will have uniform amounts of support throughout its body.
Memory foam mattresses are famous for their slow-moving, body-contouring features. For some, this is a very comfortable hugging feeling, while for others this feature makes them feel “stuck” in the foam.
This is because when you shift positions, the foam may have a slow response time that causes it to retain its previous shape before very gradually transitioning to your new weight distribution.
How fast you would like the response time to depend on you. A very slow response time will hug you tightly and can feel comfortable and sink-in luxurious.
A fast response time will give the mattress a bit of a bounce and prevent you from feeling suffocated when you adjust yourself. This is a matter of preference, so choose accordingly!
For a long time, memory foam mattresses had a tendency to overheat. This makes sense given its material’s make, which naturally retains more heat, but sweating at night is never a comfortable situation.
Worse still, if your mattress makes you sweat, the moisture can actually cause faster deterioration or even serious damage to a memory foam mattress.
Luckily, most modern mattresses of this variety have characteristics that help temperature regulation, whether it’s from the way the foam itself is made or because of added features in the layers of the mattress.
Memory foam can be infused with heat diminishing gel, have a ventilated system, or allow for better, more even air flow. Whatever the case, make sure that the mattress you purchase has some sort of way to combat the heat.
Health and Safety
Memory foam mattresses typically have an off-gassing odor when they first arrive, which can carry an unpleasant and chemical-like smell.
This is a cause of worry for many buyers, so you should opt for a mattress that you know is made with safe ingredients and doesn’t use volatile organic compounds, flame retardants, or harmful, toxic chemicals during manufacturing.
Memory foam products that have been made in an environmentally conscious or safe and healthy manner typically have certifications, such as the CertiPUR-US certification or the GREENGUARD certification.
Keep an eye out for those when purchasing, as they are usually also hypoallergenic and safe for those with allergies or skin conditions!
Trial and Warranty
One of the best parts about buying memory foam mattresses from Amazon is the automatic trial period you get.
Amazon typically offers a 30-day period during which you can ask for returns or exchanges fuss-free, and this company policy overrides that of the brand’s in most cases if you are purchasing directly from Amazon.
With that being said, some mattress brands may also offer extended trial periods so you can attempt sleeping on your new mattress for a long time before deciding whether or not you want to keep it.
You should also take a look at the warranty period for each mattress you peruse. While warranty length doesn’t necessarily equate to mattress quality, it does have some bearing on it, and it can help you make a purchase with better peace of mind.
For example, a mattress with a one-year warranty will likely suffer wear and tear faster than one with a 10-year warranty.
