Toppers have been heavily marketed recently and many restless sleepers have tried using a topper to solve their mattress problems.

The price of a Mainstays topper varies from about $40 for the Twin-sized one to $80 for the King size, which makes them very affordable, especially when you take into consideration the fact that some toppers are up to $450.

Today we’ll review this product but also teach you when and why to buy a topper – in particular, Mainstays Gel Infused Memory Foam Topper. It seems that there’s a lot of people who just want to ”save” their old mattress and save some money so they get a topper – although this works great on some old mattresses, it could be a disappointment for others. Toppers can be used to soften hard mattresses or to cover somewhat old ones, but they are definitely not designed for very old, sagging, and uneven mattresses.

Mainstays Topper Pros and Cons

– It’s comfortable
– Affordable-
– Conforms to the body and relieves pressure points
– Some toppers arrive with a strong smell
– The memory foam retains a lot of heat
– 2” is too thin for larger individuals

The 2-inch topper is great for individuals who need more comfort, that is, to soften their bed a bit. Heavier people are likely to find it too thin. It gives the conforming, “hugging” feel which is pleasant and soothing for a while because memory foam retains so much heat that a number of users had to return it solely for this reason. But again, if you are not a heavy person, you’ll probably not sink so much into the topper and it will not cause you to overheat.

As for the smell, it seems to depend on the batch – some people get a topper with a faint smell that quickly disappears, and some report it being way too strong. 

Either way, the topper is made to relieve pressure points and it does this job very well as long as you use it on an even surface. This is to say that you should not buy a topper as a quick fix for a sagging mattress – even though it is quick, it certainly isn’t a long-term fix. 

You can use it to add comfort until you buy a new mattress. Some mattresses can be old and uncomfortable but still keep a certain amount of evenness which can be a good base for a topper like this one.

Is the Mainstays Topper for Me?

You should buy a Mainstays topper if:

  • Your mattress is (relatively) new but too firm
  • You are not a hot sleeper
  • You want to prolong the life of your mattress
  • You don’t have a problem with memory foam itself

You shouldn’t buy a Mainstays topper if:

  • You want a luxury topper
  • You have an old and uneven mattress/bed that causes you great pain (that calls for a new mattress)
  • You expect it to have a cooling effect because it’s “gel-infused”

Mainstays 2-inch topper product information

Mainstays 2” topper
Material100% gel-infused memory foam
Thickness2”. The store also offers 1.5” and 3”.
SizeTwin, Full, Queen, King
Color and designIt’s just blue-dyed memory foam, nothing protecting it on the outside.
PriceFrom $40 for a Twin to $80 for a King

Even though the topper is infused with gel, the gel itself is not really visible and it doesn’t make a sleeper feel cool. 

Since this is just a piece of memory foam, it would be smart to protect it with something – perhaps use two fitted sheets, one to remain over the topper at all times and the other to be slept on and washed regularly.

Here we’re reviewing the 2” topper since it would work for the majority of people, but if you need only the slightest change or on contrary, a thicker slab of foam, you should know that there are two more options – 1.5” and 3”.
