It’s only natural that your mattress changes  over time. As more weight presses on it throughout the years and it undergoes general wear and tear, you might start experiencing your bed as feeling softer or firmer than when you first got it. One way you can remedy this is by adding a mattress topper.
Today, I’m going to be specifically talking about the Sleep On Pure Green Natural Latex Mattress Topper, an environmentally friendly topper that’s available in three different thicknesses (one inch, two inches, and three inches) and three different firmnesses (Soft, Medium, and Firm). For the purpose of this review, I decided to take a look at the most popular topper, the two-inch Soft model.
Will this topper actually soften up the mattress without decreasing support or sleeping warm? Continue reading my full Sleep On latex mattress topper review below to find out.

Construction and Materials
The Sleep On Latex Pure Green Natural Latex Mattress Topper is constructed from 100 percent natural Dunlop latex. No synthetic latex materials, fire retardants, or fillers are used in this topper whatsoever.
As a material, all latex is naturally responsive and cooling, but Dunlop tends to be a little softer and less bouncy than the other type of latex, Talalay. Sleep On chose Dunlop over Talalay so they could create a mattress topper with a bit more plushness. You can read about the differences between Dunlop and Talalay latex here.
As I said earlier, sleepers have the option of purchasing the Sleep On topper in three different thicknesses: one inch, two inches, and three inches. Each thickness is available in the dimensions for a twin, twin XL, full, queen, king, or California king bed. The level of thickness isn’t intended to change the feel of the topper much, but rather give the sleeper the option of different heights to place on top of their mattress.
Additionally, Sleep On Latex offers an organic cotton cover that can be added to the topper. For this test, I went ahead and ordered the topper with the organic cotton cover (note that this will add to the final cost). Made from a blend of organic cotton (80 percent) and polyester (20 percent) this cover is designed to add an extra layer of protection to the mattress pad. While some may prefer a 100 percent organic cotton cover, Sleep On Latex decided to use a small amount of polyester to avoid shrinkage when washing the cover.
Feel and Comfort
The Sleep On Latex Pure Green Natural Latex Topper adds quite a bit of softness to virtually any mattress. Atypical to the more traditional memory foam toppers and mattress pads, it offers deep sinkage while also giving you a quicker response time.
When I first lay down on the topper, I sank almost entirely through the two inches of material, but never felt like I was trapped or stuck in the foam. Instead, the mattress topper was able to sink with me and respond immediately as I rolled over and changed positions.
I decided to test out the Sleep On topper on several different mattresses, all with varying degrees of firmness. I started with a bed that scored an 8 out of 10 on the mattress firmness scale, where 10 is the most firm. But after spreading out the topper, I felt as if it had dropped to a 5.5 out of 10. That said, I didn’t see much of a difference in terms of support. Instead, the topper seemed to have added the softness and pressure relief without changing the foundation of the mattress below.

Next, I tried the topper on the Sleep On Latex mattress — specifically, the nine-inch medium-firm model. Normally, this mattress feels like a 6 or 6.5 out of 10 on the firmness scale. After adding the topper, though, it felt closer to a 4.5 out of 10. Compared to my experience on the firmer mattress, I definitely enjoyed the topper more on the latex mattress, but once again felt that it didn’t alter the bed’s support too much. You can read more about the bed itself in our full Sleep On Latex mattress review.
I should also note that the topper felt very cooling on both mattresses. As a 100 percent latex topper with an organic cotton cover, there was a high level of breathability. Not once did I feel as the Sleep On Latex mattress topper created a warmer sleeping surface.

Who Should Buy the Sleep On Latex Natural Latex Mattress Topper?
I would recommend the Sleep on latex natural latex mattress topper to sleepers who:
- Want to soften their mattress anywhere from 20–30 percent – By adding the Pure Green natural latex topper, you can expect to see a firm mattress move to more of a medium feel and a medium mattress to more of a soft feel. That’s a difference of 2–2.5 points on the Sleepopolis firmness scale. Bear in mind, this is based on the Soft version of the topper. I would expect the Firm version to increase firmness by that 20–30 percent margin and the Medium version to increase or decrease firmness by 10–15 percent, depending on if it’s placed on a soft or firmer mattress.
- Want a latex topper – By adding a latex topper to your mattress, you should see improvements in response time, bounce, and cooling. You’ll want to be sure you’re a fan of a more responsive feel before moving forward with this topper.
- Want organic / natural products – With with 100 percent natural latex construction, this topper is one of the more organic sleep accessories Sleepopolis has tested to date. If you’re looking for a topper, but want to avoid any chemicals or synthetic materials, the Sleep On Latex topper is certainly a good choice.
