What experts didn't like

Foam is not very dense, so those wanting a firmer topper may want to opt for another model.
- BestReviews
One thing to be aware of is that because the Zinus is so thin, it sometimes has trouble puffing up to its full size when it comes out of packaging.
- Sleeping Culture
Some back sleepers may find it too soft

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.

The Mattress Topper Buying Guide

  • Comfort starts with keeping you cool, especially if you tend to sweat while you sleep. With the EASELAND Queen Pillow Top Mattress Topper, you get the power of cooling gel to keep overheating at a minimum. With this mattress, the memory foam is infused with a cooling gel that prevents heat from being trapped in the layers. Other toppers use a breathable fabric for improved airflow.
  • Each mattress topper has its own unique way of making you more comfortable while you sleep. Some models have a 2-inch thick down-alternative layer attached to the cover, topped by a 2-inch thick layer of gel-infused memory foam. Others use memory foam to conform to your body. There are even toppers that have an open-cell technology to help 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. This problem is easily remedied by allowing the topper to air out for a short time.
  • Although you can find cheaper mattress toppers, you won’t get nearly the quality that you’ll find with a more expensive mattress topper. Either way, you’re sure to find a mattress topper that fits within your family’s budget.
