Sleep Innovations has been designing and selling memory foam mattresses since Amazon was still just a bookstore (and that was way back in 1996).
Over the past 20 years, they have made tremendous improvements on their product offerings and expanded their product lines to include more than just mattresses.
Today, they sell a range of bedding products, including pillows and mattress toppers. The Sleep Innovations 4″ Dual Layer Mattress Topper is their top product in this category at the moment.
It has also received an excellent rating of 4.3/5 stars based on more than 2,200 Amazon customer reviews at the time of writing, due to the unique combination of body-cradling comfort and spinal support that it provides.
However, is this the best mattress topper for you?
As we have observed time and time again, sleeping preference can be very different from one person to the next. What’s best for us may not be the best fit for you.
Therefore, this Sleep Innovations 4″ Dual Layer Mattress Topper review will not revolve around individual experiences. We focus on giving detailed and objective facts about the mattress topper, as well as a summary from hundreds of customer feedback to help you form an informed buying decision.
Sleep Innovations 4″ Dual Layer Mattress Topper Review
Since its establishment in 1996, Sleep Innovations has never operated their own brick-and-mortar stores.
They sell their products via online channels such as Amazon or retail distributors such as Walmart to keep the operating costs low and translate the savings into lower prices for consumers.
As a result, even though the Sleep Innovations 4″ Dual Layer Mattress Topper consists of 2 foam layers instead of single foam layer like many of its competitors, it is still pretty affordable for the quality you are getting.
Granted, it is a bit more expensive from the rest of our recommendations in this category, but it is geared towards consumers of specific needs.
While single layer memory foam mattress toppers are great for adding comfort to a relatively firm mattress, the Sleep Innovations 4″ Dual Layer Mattress Topper comes with its own comfort and support layers to help with spinal alignment.
- First Layer: 2″ quilted fiber-filled mattress pad. This layer works in conjunction with gel memory foam layer to provide comfort and spinal support to back, stomach and side sleepers.
- Second Layer: 2″ cooling gel memory foam layer. Whether you sleep on your side, back, or stomach, you need a soft layer that contours to your shape to prevent painful pressure points. This layer distributes your body weight evenly to prevent pressure build-up on neck, shoulders and back. The open-cell structure helps with heat dissipation and keeps the sleeper cool throughout the night.
- Mattress Topper Cover: Both layers are held together by a machine-washable cover.
It’s your choice to use either layer as the side that’s facing up. The contoured side gives you lighter cradling comfort, but it’s recommended that you try both sides and choose the one that feels best to you.
Available Sizes: Twin, Full, Queen, King, California King
Material: Fiber-Filled Pad, Cool Gel Memory Foam
Full Expansion Time: 24-48 hours
Warranty Period: 10 years
What sets the Sleep Innovations Dual Layer Mattress Topper apart from the rest of its competitions are the inclusion of an extra long warranty (10 years vs 3 years of main competitors) and a fiber-filled support layer for spinal alignment.
Normally, memory foam mattress topper comes in just a single layer of body-contouring memory foam gel to provide the “sinking feeling” and extra comfort on top of a firm mattress surface.
In these cases, the mattress toppers don’t provide support for spinal alignment. They do relief stress and pain of pressure points thanks its body-cradling properties, but spinal support still comes from the firm mattress underneath it.
For Sleep Innovations Dual Layer Mattress Topper, the gel memory foam layer serves the same purpose of providing comfort via its cooling gel memory foam layer (blue layer).
On the other hand, the quilted fiber-filled mattress pad of the mattress topper (white layer) works to provide some support to spinal alignment that isn’t present in other single layer memory foam toppers.
This makes it an ideal choice for customers who want a memory foam mattress topper that not only adds body-cradling comfort to their existing mattress, but also some support to common pressure points such as neck, back, stomach and shoulders.
It is not unusual for new memory foam mattress and mattress toppers to release odors right after unpacking (known as off-gassing), and the Sleep Innovations 4″ Dual Layer Mattress Topper is no exception.
Even though it does not happen to every new mattress toppers, it does happen on a pretty regular basis. Fortunately, potential odors usually dissipate within 24 hours of airing in open room.
At the same time, it is also a good practice to leave the topper alone for at least 24 hours before sleeping on it to allow for full expansion.
This memory foam mattress topper is rolled, vacuum-packed and ships in compact boxes. The heaviest variant (California King) weighs around 31 pounds, so be prepared to do some heavy lifting when you move it around your house.

What Do People Say About Sleep Innovations 4″ Dual Layer Mattress Topper?
There are quite a bit of variations between individuals in terms of preference for mattress toppers – whether it’s firm, hard or soft, so we choose to look at hundreds of reviews for each product to capture the overall sentiment from the customers.
Overall, the Sleep Innovations 4″ Dual Layer Mattress Topper has managed a decent rating from its customers, with 72% of them giving a 5-stars rating and 11% giving a 4-stars rating (out of more than 2,200 customer reviews at the time of writing).
Most customers are satisfied with the affordability and choice of material for the mattress topper, even after considering its slight premium over its competitors.
For those who care about the manufacturing process and location, it is made entirely in the USA and is compliant to safety standards of the industry, such as the CentiPur-US and California TB117-2013 guidelines.
Majority of sleepers reported that the mattress topper stays cool throughout the night thanks to its open-cell structure cool gel memory form. This is a huge plus, as trapping heat is a common weakness of memory foam due to its body-cradling nature.
The open-cell structure of Sleep Innovations 4″ Dual Layer Mattress Topper dissipates heat effectively and doesn’t trap body within the layer.
Customers also like the fact that it is more supportive for spinal alignment compared to other competing memory foam mattress topper, as it is one of the only toppers that feature an additional fiber-filled mattress pad layer.
Of all the customers who rated 3-stars and below (consists of 17% of all ratings at the time of writing), a sizable portion of it comes from error in the shipping process.
It is noted that some customers only received the memory foam layer for their purchase, instead of both layers (cool gel memory foam and fiber-filled layers) along with the mattress cover.
Apparently, the same problem has persisted for a few years, so if you encounter the same issue you’ll have to contact Amazon for re-shipping. After that, you’ll have to ship the original memory foam layer that you received back to Amazon.
Admittedly, that’s an unnecessary hassle on the part of the customers, but it’s good to see that the rating of the mattress topper could have been higher if it’s not for the shipping issue.
Some other complaints include the usual suspect for memory foam mattress products, including potential odors that come with brand new purchases. If you encounter this problem, just air the topper out for at least 24 hours and you should be good to go.
