Whatever the reason you're in the market for a mattress topper — whether your current mattress is old and lumpy or maybe you just want to make it a little softer — I can promise you won't regret this purchase. A good mattress topper can be the difference between a good and bad night's sleep. And if you suffer from back pain like me, then it can be a true game-changer.
I know Allswell for its budget-friendly mattress in a box, I didn't realize, however, that they also sell toppers — the Allswell 4-Inch Memory Foam Mattress Topper is the one I slept on for a month to review. I tested its motion transfer and support and was pleased with its performance. If you’re looking for an affordable yet effective topper, this mattress topper might be the right choice — especially if you don't have the budget to replace your mattress right now. Plus. there's the fact its affordable price point makes it a practical choice for many, and the topper can accommodate side, stomach, and back sleepers. It’s an easy way to customize the way your mattress sleeps so that it’s better suited to your preferences.
The Allswell topper features a dual-layer memory foam design. The top two inches are designed for comfort, while the bottom two inches provide support. The Coolflow foam upper layer wicks moisture and maximizes airflow to keep you cool. The topper is also infused with copper gel for its antimicrobial and cooling properties.
Allswell Mattress Topper review
TLDR: What I thought of the Allswell Memory Foam Mattress Topper
Between its relatively low price point and multi-layer construction, this mattress topper is well worth buying in my opinion. It does an impressive job at preventing motion transfer, and it adds significant softness to a bed. The topper performed consistently during the one-month testing period, and though there were minor inconveniences like its powerful off-gassing smell, it offers great value for the price.
There's no doubt that this mattress topper is well-suited to anyone who prefers a softer surface than what their current mattress can offer. It could be ideal for someone who is working with an older mattress or a mattress that just doesn’t meet their preferences. Thanks to its ability to prevent motion transfer, it’s also ideal for couples and anyone who might share their bed with kids or pets. It would also be a fantastic way to add comfort to a cheap dorm mattress.
Because this topper is so soft and creates a sinking sensation, anyone who prefers a firmer mattress might want to give it a miss. If you have difficulty shifting on a softer mattress, this topper could make it challenging to move around at night. Its soft edges with a lack of support also mean it’s not a great choice if you depend on the edge of your mattress to support you as you get into and out of bed.

Unboxing the Allswell Memory Foam Mattress Topper
The Allswell 4-Inch Memory Foam Mattress Topper Infused with Copper Gel arrived in an Allswell box that was packed inside a standard cardboard shipping box. Both boxes arrived in good condition
The Allswell box is equipped with handles, but I didn’t initially discover them because they’re along the box’s longest sides, rather than on the ends like where you would normally find them. The topper was tightly wrapped in plastic and was easy to remove from the box, though this queen-size topper was surprisingly heavy at 19 pounds.
Within the box, I found a “welcome” card including instructions for unwrapping the topper. The manufacturer recommends that you unroll the topper on a flat surface and give it 48 hours to recover in a well-ventilated room.
Unwrapping the topper was easy. I used a pair of scissors and carefully cut through the plastic. The ends of the topper were not wrapped, so it was easy enough to slip the end of the scissors beneath the plastic.
While I appreciated the fact that the unwrapped ends made it easy to unpack the topper, that design also allowed some sort of debris to work its way down into the plastic. You see, the mattress was folded in half, then folded in half again and rolled up — the spotty flecks were along those edges that were exposed while in the box, so they were scattered along the surface, toward the middle and toward one edge. This black debris was minimal, but it did stain the topper in areas. Soap and water did little to remove it.
Once unwrapped, I could tell immediately why the manufacturer recommended placing the topper in a well-ventilated room. While I have purchased multiple mattresses and toppers that shipped compressed and wrapped in plastic, this topper has the strongest off-gassing odor that I have experienced. Even after 48 hours the odor remained and didn’t fully dissipate until about 72 hours after unwrapping. I could not have slept in the room with the topper, and I would recommend giving the topper an extra day or two to air out before using it.
When I unwrapped the topper, it appeared to have been pinched and compressed into a swell while in the plastic. After about five hours, though, the topper had recovered and any sign of that imperfection was gone. Once recovered, the queen topper was a perfect fit for my queen bed.
Is the Allswell Memory Foam Mattress Topper comfortable?
This mattress topper features a two-layer construction designed to give both comfort and support. The bottom layer is made of memory foam, and the top layer of Coolflow Foam is an open cell memory foam designed to allow for plenty of airflow while also wicking moisture. The topper is also infused with a copper gel, while graphite helps to transfer heat away from the body.
I found that the result is a very soft topper, even though it is marketed as being firm. The upper layer compresses easily, allowing you to sink down into it. However, I was impressed to see that the bottom layer does provide a sense of support. That bottom layer doesn’t compress, even under my full body weight, avoiding the “bottoming out” feeling that I have experienced with other memory foam toppers.
This results in a feeling of being almost stuck in the topper. Once positioned, it’s difficult to shift around, and it feels like I have sunk down into the topper. When laying close to the edge of the bed, my weight causes the edges of the topper to pull up, enhancing that feeling of sinking and being surrounded by the topper, more than lying on top of it. Note: Allswell also offers thinner versions that should sink less.
This isn’t all negative, however. The topper offers excellent comfort. I found that it effectively prevented pressure points, and I naturally relaxed to the surface. I suffer from back pain and, while the topper didn’t reduce the pain I feel at night, it also didn’t aggravate it. I did notice that I didn’t feel pressure in my knees, ankles, or heels like I sometimes experience when sleeping on a firmer surface. It could be a good solution for those investigating the best mattress for back pain.
This topper excels when it comes to preventing motion transfer. I am joined in bed by several rambunctious cats during the night, but I couldn’t even feel them get onto the bed. While I often wake up when a cat moves, bathes, or just walks around the bed, that did not happen while testing the topper. Of all the topper’s features, I’m most impressed by its capability to prevent motion transfer.
I also tested the motion transfer using a glass of water. The first challenge was getting the glass to sit securely on the topper; it repeatedly sank and tipped. Once positioned, I found that I had to be 12 inches or closer to the glass when pushing or rolling on the topper to vibrate the water within the glass. Thanks to this excellent motion transfer prevention, I believe this topper is well-suited for partners or anyone who has pets or kids who join them in bed.
Because the topper is generously sized at four inches high, it adds significant height to my bed. If I had a mattress of a standard height, that wouldn’t be an issue, but I placed this topper on a Dreamcloud mattress that already measures 14 inches high. Even though I have deep-fitted sheets, they no longer fit both the topper and the mattress, and the bed’s height makes it difficult to get into and out of.
That is exacerbated by the lack of edge support. While the bottom layer of the topper does offer some support, the top layer compresses almost completely, so the edge feels soft and rounded. This design could be problematic for sleepers who depend on the firm bed edge to get into and out of bed safely.
Is the Allswell Mattress Topper breathable and cool?
Because I sank so deeply into the topper, I assumed that I would be too hot, but I was pleasantly surprised to see that I was comfortable all night long. During my time testing this topper, temperatures climbed to 85ºF indoors. I never felt that the topper was making me hot, or that it slept any hotter than my usual mattress. I wouldn’t say that it made me significantly cooler, but I did sleep much cooler than expected.

Real Homes' Review Process
There's much more to how we test mattresses (and toppers) ICYWW, but for a brief overview, our mattress topper testers are all required to sleep on their bed with the new product for a minimum of three to four weeks before reaching their verdict, testing the topper according to a strict brief. This allows Real Homes to compare and contrast their mattress topper experiences to find the best product. During the review, we will pay close attention to comfort, support, cost, and how it lives up to claims. We will also choose a reviewer depending on how they sleep, and we will ensure that this matches the type of topper we give them.
