What experts liked
The Malouf Isolus 2-Inch Ventilated won’t transform your bed, like the Tempur-Pedic topper we love, but it does add a good amount of cushioning. It also avoids the major pitfalls we found with cheaper toppers, which were smelly, hot, and bottomed out onto the bed underneath.
- New York Times Wirecutter
It’s ventilated to allow air flow and prevent heat retention.

What experts didn't like
Although the Malouf is still relatively expensive, it’s the only sub-$200 model we feel comfortable recommending.
- New York Times Wirecutter
And despite being better than other memory foam toppers in terms of heat and initial smell, you may find that there’s still a little of both.

From The Manufacturer

A mattress topper is a great solution if you want to add support and soften up your current mattress. Using this 2-inch topper will bring the comforts of a new mattress without breaking the bank. Our memory foam formula offers superior comfort and pressure relief. The molded foam is better able to conform to your body and cushion the natural pressure points of your shoulders and hips. This will remove sleeping pains and naturally align your spine. The most common complaint against memory foam is heat retention. Combining open-cell construction and ventilation, we strategically created a memory foam that will optimize air flow, helping you sleep cooler. The added circulation will also prevent mold from growing in your mattress. We offer a 3-year warranty that protects the mattress topper against manufacturer's defects. CertiPUR-US is an independent company that confirms our foam meets specific criteria for safety of material used, physical performance, low indoor emissions, and environmental stewardship.

An Overview On Mattress Toppers

A mattress pad protects your mattress, but it doesn’t really make it more comfortable. For that job, you need a mattress topper, a relatively thin layer of material that rests atop your mattress to make it softer. But a mattress topper does more than simply offer a thin layer of cushioning. With the right one, you’ll also get a cooling effect that is far better than the unventilated toppers of previous generations.

If cooling is important to you, make sure you look for a topper that’s designed to keep you cool. Some use ventilation for that, but others use technology like cooling gel to provide even more assurance that you won’t wake up in the middle of the night in a pool of sweat. Often, it’s just simply the design of the topper itself that keeps sleepers cool.

Of course, overall, you’ll be looking for a topper that makes your mattress comfortable for sleeping. You’ll find with most mattress toppers, memory foam is the name of the game, but memory foam isn’t without its issues. Modern products are constructed to resolve the common problems that come with using the material.

Mattress toppers require chemicals during the manufacturing process and, unfortunately, this can lead to unpleasant odors when you bring them home. You won’t get away from that issue completely, but some toppers do cut down on this more than others. For best results, air your topper out for a few hours, preferably outside, before putting it on your bed and covering it with a fitted sheet. You can also set a bowl of vinegar in your bedroom for a few days to absorb the smell.

Lastly, there’s the price. It’s important to note that you can find very affordable mattress toppers on the market, but many of them have all the issues that higher-end toppers work to address. You’ll pay a little more for a comfortable, cooling sleeping experience, as well as avoiding the odor problem that comes with less expensive versions.

DYWM Fun Fact

Astronauts spend hours in a seated position, working hard to carry out various missions. So, it’s no surprise that memory foam technology was actually invented by NASA with the goal of coming up with a way to make space shuttle seats more comfortable. In 1966, NASA called in an inventor named Charles Yost to handle the project.

Yost developed a specialized foam by injecting gas into a polymer matrix, creating cells that were solid but behaved like liquid. When compressed, the cells shifted around, with a result that Yost called “slow spring back foam.” Best of all, body heat seemed to soften the material, causing it to remain firm in the areas that were still cool, which created a body-contouring effect that was more comfortable than traditional foam.

The Mattress Topper Buying Guide

  • Comfort starts with keeping you cool, especially if you tend to sweat while you sleep. Toppers like the Isolus Ventilated Memory Foam Mattress topper rely on their ventilation to keep air moving through them. But with the Sleep Innovations Dual Layer 4″ Gel Memory Foam topper and DreamFoam Bedding 2″ Gel Swirl Memory Foam Topper, you get the power of cooling gel to keep overheating at a minimum. With these mattresses, the memory foam is infused with cooling gel that prevents heat from being trapped in their layers. The LUCID 3″ Ventilated Memory Foam Mattress topper uses evenly-spaced ventilation holes, creating an open-cell design for improved airflow.
  • Each mattress topper has its own unique way of making you more comfortable while you sleep. The Sleep Innovations Dual Layer 4″ Gel Memory Foam topper has a 2-inch thick down-alternative layer attached to the cover, topped by a 2-inch thick layer of gel-infused memory foam. Both the Isolus Ventilated Memory Foam Mattress topper and DreamFoam Bedding 2″ Gel Swirl Memory Foam Topper use memory foam to conform to your body, but the open-cell technology of the LUCID 3″ Ventilated Memory Foam Mattress topper helps prevent those body impressions that can make memory foam less comfortable.
  • You’ll always have at least a trace of odor when you unwrap a new mattress topper, mostly due to the chemicals injected into them. Both the Isolus Ventilated Memory Foam Mattress and Sleep Innovations Dual Layer 4″ Gel Memory Foam toppers have a slight odor, but airing them out for a short time will take care of it.
  • Although you can find cheaper mattress toppers, you won’t get nearly the quality that you’ll find with a more expensive mattress topper. The DreamFoam Bedding 2″ Gel Swirl Memory Foam Topper retails for less than $70, with the LUCID 3″ Ventilated Memory Foam Mattress topper selling for less than $100. You’ll pay a little more for the Isolus Ventilated Memory Foam Mattress and Sleep Innovations Dual Layer 4″ Gel Memory Foam toppers, but you’ll still find them for less than $200.
