Mattress Toppers in Brief and Memory Foam

Essentially, a mattress topper is a removable bedding that can be put on top of your old mattress to provide extra support and cushioning. It’s an extension of your mattress, if you will.

If you have an old mattress that has turned stiff or uncomfortable over the years, a soft mattress topper can rejuvenate it and make it feel like a brand new mattress again. Besides soft toppers, there are also firmer types that can be used to make too-soft mattresses firmer and more supportive.

The best rated mattress topper also doubles as a protective layer for your mattress, extending its lifespan, too.

Toppers can be made from a variety of materials, one of which is memory foam. It's cheaper than other materials like Latex and has great cushioning properties to boot. The foam can conform to the shape of your body, distributing your weight, and easing the pressure on sensitive pressure points.

As a result, in most Sleep Innovations 4-inch dual layer mattress topper reviews, customers reported great comfort while laying on memory foam toppers. Particularly, they are a huge hit among those with achy joints and medical conditions.

Not many people are aware of this useful add-on despite it being sold everywhere. You can probably find the Sleep Innovations mattress topper at Costco. If not, other online retailers like Amazon also sell them.

Overview of Sleep Innovation Memory Foam Topper 4-inch

The 4-inch topper actually measures about 2 inches thick if you only count the memory foam layer, so the Sleep Innovations 2 inch memory foam mattress topper name would be more fitting. The thing about this topper is that it doesn’t just include the memory foam. There’s an additional 2-inch fiberfill comfort layer on top to improve comfort.

It’s a uniquely different design compared to the average toppers, which are usually only made up of the topper itself. Rather than feeling like you’re sleeping on top of a block of foam, with the addition of the comfort layer, the Sleep Innovations topper feels pleasantly pillow-like.

A majority of customers love the elasticity and support of the memory foam, which is the primary selling point of this topper. The foam provides optimal spine alignment and gives support to crucial areas to decrease pain. For this reason, people with bad backs or joints problems have also put in good words for this topper.

Sleep Innovations injects cooling gel into the foam to facilitate cooling. Memory foam has a reputation for being hot to sleep on, so the gel is meant to help with that. The Sleep Innovation memory foam topper doesn’t retain body heat and scatter them all, making the sleeping surface pleasantly cool through the night.

An optional washable cover comes inside the box with the topper. It can be easily removed and machine-washed when needed. If you don’t like the accompanying cover, then cover replacement is simple. Buy a new one that you like better and switch them.

The topper has a CertiPUR-US® certification, which means that it’s non-toxic and isn’t manufactured with harmful materials like lead or mercury. You and your family’s health are safeguarded.

Depending on the size of your mattress, Sleep Innovations gives you five different size options: Twin, Full, Queen, King, and California King. Regardless of whether you’re looking for a queen mattress topper or a king mattress topper, choices are available.

The smallest size (Twin) weighs about 16.9 pounds, which can be easily managed by two people. But the largest sizes (King and California King) weigh over 25 pounds. You’ll have to call in your friends to help you move it in if you buy one of the larger sizes.

Memory foam toppers like this one tend to have a “new” smell after it’s unboxed and normally will take a couple of days for it to go away. According to many Sleep Innovations 4-inch dual layer mattress topper reviews, this topper takes longer than normal (a few days) to get rid of the offensive chemical smell.

Polyurethane Memory Foam

Like other memory foam toppers, this one is made from a special combination of Polyurethane (PU) and chemicals to give it its special “shape-conforming” ability. The sensation of the foam “hugging” the user’s body is an oddly nice sensation that’s caused many to swear by memory foam once they have tested it out.

The foam doesn’t just stay in one shape. When pressure is released, it gradually returns to normal or “bounces” back.

As nice as it is to use as a sleeping surface, there are many drawbacks that you will have to deal with. First, among the many applications it has, PU foam is used as an insulator. That means it doesn’t conduct thermal energy well. Without a cooling feature, memory foam toppers have a tendency to become swelteringly hot to those who aren’t hot sleepers.

This is a problem that many manufacturers— including Sleep Innovations— have managed to mostly fix by adding a layer of cooling gel to the foam. We’ll go through that later.

Another problem with memory foam is that it’s very tricky to maintain. A foam topper cannot be machine-washed. If you do, it will be irreparably damaged. Instead, all you can do to clean your topper is spot cleaning with a damp cloth. All of the “How to Clean Memory Foam Mattress Topper” instructions you find online will boil down to just that.

Last but not least, there’s the “new foam” smell that we mentioned earlier. Fresh memory foam has a very obnoxious chemical scent to it that can be off-putting for a lot of people, especially those with sensitive noses. The smell generally isn’t toxic, but regardless, if you have respiratory conditions, we recommend that you let the topper air out for several days until the smell disappears before using it.

Cooling Gel

The best rated mattress topper has a layer of cooling gel sandwiched between the memory foam and the fiberfill comfort layer. Like we mentioned before, memory foam doesn’t vent heat well and can become very hot. The gel soaks up your body heat and dissipates it through the night, ensuring that you’re cool and comfortable at all times.

Fiberfill Comfort Layer

The fiberfill comfort layer sets the Sleep Innovation memory foam topper apart from other toppers. The plush material lends a squishy, pillow-like sensation to the topper. If you’re looking to soften your bed, having this extra layer can be the decisive factor.

Customers who have tried out the topper for themselves said that it feels like they’re sleeping on a “down-filled pillow.”

It is secured to the memory foam layer via elastic edges and is removable. You can take it off of the foam layer and put it into the washing machine to clean when it starts to get dirty.

A potential problem that you may have to watch out for about the fiberfill top is that it seems to have a single stitch. If one of the stitches was to give out, the whole top could potentially unravel

CertiPUR-US® Qualification

Notably, the topper has a CertiPUR-US® qualification. This basically means that the topper contains no noxious materials that can harm your health or worsen the air quality in your home with off-gasses.

Speaking briefly of CertiPUR-US®, this is a safety standard designed especially for foam products like mattresses, toppers, and other foam furniture. Polyurethane foam can be very harmful if they’re not manufactured correctly. Looking out for a CertiPUR-US® mark is a good way of distinguishing high-quality foam products from low-end versions, and reputable makers from the dubious names.

The criteria for a product to become qualified is quite extensive.

  • • Manufactured with no ozone depleters
  • • No heavy metals (like mercury and lead)
  • • Does not contain prohibited phthalates
  • • Low VOCs (Volatile Organic Compounds)
  • • No BPDE (Polybrominated Diphenyl Ethers), commonly found in fire retardants
  • • Does not contain formaldehyde


If this topper isn’t exactly what you have in mind or you want to see a few more options before making your decision, we’ve got you covered. The following are some of the alternative best rated mattress toppers, other than the 4-inch Sleep Innovation memory foam topper.

#1- LUCID 2-inch Zoned Gel MemoryFoam Mattress Topper

If you seek a topper that’s even more affordable than the Sleep Innovation 4-inch topper, the Lucid 2-inch isn’t a shabby choice.

This topper is also made from memory foam and is infused with cooling gel to help with body heat regulation. Just as the Sleep Innovation has a fiberfill top to distinguish itself from the rest of the competition, this LUCID topper has something of its own, too.

The LUCID topper’s sleeping surface has five specially designed “body zones.” These zones are molded to improve comfort, provide extra support, and ease pressure on the joints and common pressure points of your body.

The available sizes are more extensive than the Sleep Innovation. There are 7 options: Twin, Twin XL, Full, Full XL, Queen, King, and California King. Besides sizing options, you can also choose between a 2-inch version and a thicker 3-inch version.

#2- LUCID 3-inch Bamboo Charcoal Memory Foam Mattress Topper

The key difference between this one and the previous two products is that instead of cooling gel, this LUCID 3 inch topper is infused with bamboo charcoal.

Bamboo charcoal is hypoallergenic (doesn’t cause allergic reactions). It also does a very effective job at regulating temperature, keeping moisture (such as sweat) in check, eliminating bad odors, and resisting bacteria growth.

If you tend to get rashes while sleeping on your old bed, this topper will significantly improve the quality of your sleep. And if you have a heart for nature, the good news is that bamboo charcoal is environmentally friendly.

#3- Pure Green 100% Natural Latex Mattress Topper

Move away from memory foam, if you don’t mind spending extra money for extra comfort and environmental friendliness.

The natural latex used in this topper is sourced from Sri Lanka and manufactured via Dunlop’s method. This method is more energy efficient, requires fewer chemicals, and gives relatively dense and springy latex rubber. The topper provides great support and comfort, being able to wrap around the user’s body in a similar fashion as memory foam.

Latex, just like memory foam, doesn’t support ventilation well. In place of cooling gel, pinholes are drilled through the topper to provide airflow. The improved airflow through the topper makes it a considerably cooler sleeping surface than memory foam toppers.

Natural latex is antimicrobial. It can resist bacteria, mold, mildew, dust mites, and fungi growth without needing extra chemical additives.

Six sizes are available: Twin, Twin XL, Full, Queen, King, and California King.

You can also opt for three different thicknesses: 1-inch, 2-inch, or 3-inch. If you’re a side sleeper, the thicker 3-inch version will be able to take the pressure off of your spine while ensuring that you don’t bottom out the topper.
