Best 4 Inch Mattress Topper Reviews
1. Best Price Mattress 4-Inch Ventilated Memory Foam Topper
This version of the Best Price Mattress Ventilated Memory Foam Topper is a lavender-infused four-inch-thick topper.
It carries the CertiPUR-US certification, which means it has undergone rigorous tests for manufacturing flexible polyurethane foam.
Review
The Best Price Mattress Ventilated Memory Foam Topper truly offers the best deal among the options we have here.
It fits full-sized beds, which are a few inches narrower than the short queen size.
- Product Design
This topper has an open-cell design that optimizes airflow to keep you cool and your mattress fresh.
Additionally, the infusion of lavender promotes relaxation, and the memory foam provides pressure relief throughout your body.
As you lay down, the memory foam will start to mold itself to the contours of your body to distribute your weight evenly.
- Product Variations
While this version has the infusion of soothing lavender, Best Price Mattress toppers also come in calming green tea and freshening bamboo charcoal.
To suit your needs, you can choose from 1.5-inch, two-inch, or four-inch thicknesses and twin, twin XL, full, short queen, queen, and king bed sizes.
- Cleaning
While having the best price is an advantage, it creates a minor disadvantage for product care and maintenance.
This mattress topper does not come with a protective cover to reduce the amount of dust it absorbs.
Furthermore, it can absorb liquids and bodily fluids.
Since it is entirely made of memory foam, your best approach for maintenance is vacuuming it regularly.
If it ever gets wet, you will need to let it air-dry. However, your best bet is to try not to let stains go dry.
Clean the stains with laundry detergent and water before leaving the topper to air-dry.
If odors remain, home remedies such as sprinkling baking soda and vacuuming afterward should do the trick.
Pros:
- Ventilated memory foam
- Herb-infused for relaxation
- Improves sleep quality
- Responsive active suspension
- Slightly shorter dimensions allow for a snug fit with sheets
- Item color indicates infused herbs
- Offers the best price among the options
- Comes with a three-year manufacturer’s warranty
Cons:
- No washable cover
- Not waterproof
- Not dustproof
2. Sleep Innovations 4-Inch Dual Layer Mattress Topper
The Sleep Innovations 4-Inch Dual Layer Enhanced Support Mattress Topper combines two inches of pillowy fiberfill and two inches of cooling gel memory foam.
Its pillowy fiberfill doubles as a removable quilted snug-fit cover that is washer and dryer safe.
Like the Best Price Mattress Topper, this Sleep Innovations Mattress Topper also carries the CertiPUR-US certification.
This certification implies that the product is proudly made in the US with environmentally conscious materials and processes.
Review
While the Sleep Innovations 4-Inch Dual Layer Mattress Topper is one of the more expensive options, it provides better value with its included mattress cover.
- Product Design
This product is like a three-in-one mattress topper. It is up to you whether to use the entire combo or just one of the layers.
The pillow top cover stretches to fit your mattress like any other fitted sheet.
While the fiberfill that doubles as a mattress cover may have the right amount of softness, the memory foam ensures you have enough support.
The gel memory foam alone is designed to cool and relieve stresses on pressure points.
Nevertheless, combining both creates enhanced plush support for the entire body, making it great for all sleep positions.
On another note, the entire product is hypo-allergenic and made only from high-quality materials to give you the best quality sleep.
- Product Variations
Unlike the Best Price mattress topper, which comes in different thicknesses, this Sleep Innovations mattress topper is only available in different bed sizes.
The size options include twin, full, queen, king, and California king.
Remember that you can choose either of the layers to reduce this mattress topper to a thickness of just two inches.
As such, it is the perfect option if you need a topper that converts from four inches to two inches.
If that doesn’t meet your requirements, there are other mattress toppers from Sleep Innovations.
You can choose from a four-inch dual-layer ultra-soft topper, a three-inch gel memory foam topper, and a three-inch instant pillow topper.
- Cleaning
When it comes to cleaning, you can machine-wash and -dry the pillow top cover.
The memory foam, however, can soak up liquids and get quite tricky to dry.
You can keep it clean through regular vacuuming. For removing stains, do spot-cleaning using water and detergent.
If ever you get the foam wet, we don’t recommend sticking it in the dryer, as the heat and torsion may damage it.
Instead, leave it outside to dry on a warm day or use some good air circulation from a fan.
Pros:
- Dual separable layers
- Pillowy fiberfill layer doubles as a mattress cover
- Three-in-one functionality
- Removable and washable top layer
- Ensures high-quality sleep
- For all sleep positions
Cons:
- One of the more expensive choices
- The top fiberfill cover does not have any other colors
- Second heaviest among the options
3. Zinus 4-Inch Green Tea TorsoTec Mattress Topper
As its name suggests, this Zinus TorsoTec mattress topper is green-tea-infused and is four inches thick.
It also uses memory foam as its primary material, but its manufacturing process involves the use of green tea extracts.
While soft, it provides sufficient support for the entire body to relieve pressure while you sleep.
Review
If you are looking for a lightweight four-inch-thick mattress topper, the Zinus Green Tea TorsoTec is your best bet.
It only weighs 10.4 pounds, which means it is easy to tuck away or transfer between different beds.
- Product Design
The Zinus Green Tea TorsoTec is a green and yellow memory foam mattress topper that can make your bed softer and more comfortable.
It employs Zinus’ TorsoTec technology, which provides better support for the lumbar region.
Aside from having infusions of green tea, the memory foam layer also contains active charcoal.
The infused green tea promotes relaxation, and active charcoal ensures that contaminants do not linger.
Zinus takes pride in its products, which carry the CertiPUR-US certification for durability, performance, and material content.
The Zinus TorsoTec comes with a handy storage strap to keep the memory foam rolled when not in use.
It also boasts a patented technology that allows the mattress topper to be efficiently compressed.
You can roll one up and keep it in a vacuum-sealed bag to save some space.
However, if the memory foam stays in storage for a long time, it may take up to 72 hours for the foam to fully expand or decompress.
- Product Variations
This version of the Zinus TorsoTec is a four-inch-thick twin-sized mattress topper, making it one of the smallest mattress toppers here.
Still, you can find it in other sizes, such as twin XL, full, short queen, queen, and king.
If four inches is too thick for you, other Zinus mattress toppers come in thicknesses of 1.5 inches, two inches, and three inches.
You may also stumble upon the two-inch and four-inch variations that include a quilted plush removable zip cover.
- Cleaning
If you ask Zinus, they won’t recommend drenching their memory foam mattress toppers.
For removing stains, it would be best to use mild soap and a clean, damp towel.
You can also prevent liquids from penetrating the memory foam by using a waterproof mattress protector as an extra layer before your sheets.
Since dust and small particles can permeate the foam, you should also vacuum-clean it regularly.
Pros:
- Lightweight
- Contains green tea and activated charcoal
- Comes with a handy storage strap
- Offers better support for the lumbar region
- Can improve quality of sleep
- Five-year limited warranty coverage
Cons:
- May take 72 hours to expand to its full size
- Does not come with a cover
- Neither waterproof nor dustproof
4. SUBRTEX 4-Inch Memory Foam Mattress Topper
The SUBRTEX Memory Foam is a four-inch-thick gel-infused mattress topper with a removable fitted cover.
Like the Best Price mattress topper, it has poked holes through either surface for ventilation.
Because of this cooling feature, the memory foam on this mattress topper can make your bed a more comfortable sleeping environment.
Review
This topper boasts a 10-year product warranty, but it also costs more than any of the alternatives.
We like that the manufacturer guarantees this mattress topper to be free of defects in materials and workmanship for that duration.
- Product Design
This SUBRTEX mattress topper is twin-sized and is four inches thick.
Its gel-infused memory foam doubles as a high-density cooling pad because of the equally spaced ventilator holes.
While these holes optimize airflow and reduce trapped body heat, the high-density material minimizes motion transfer and relieves body stress.
Plus, you’ll also like the removable fitted cover, which is made of a skin-friendly knitted bamboo rayon fabric.
This cover comes with corner straps to hold the topper in place, even for 12-inch mattresses.
Furthermore, its knitted fabric design prevents sliding, and a premium metal zipper keeps the memory foam in position.
Like any other good-quality mattress topper, it has both the CertiPUR and OEKO-TEX certifications for durability, performance, and content.
- Product Variations
Aside from four inches, this mattress topper also comes in two-inch and three-inch thicknesses.
You can buy it in different sizes, including twin XL, full, queen, king, or California king.
- Cleaning
We like that the removable fitted cover is machine-washable. Even so, the best cleaning method for the memory foam is vacuum-cleaning.
If stains permeate the cover, use a damp towel with a gentle detergent to spot-clean the memory foam.
Pros:
- Infused with cooling gel
- Uses ventilated high-density memory foam
- Has a removable and washable cover
- Provides a healthier sleep environment
- Comes with a 10-year product warranty
Cons:
- Priciest among the options
- Not waterproof or dustproof
- May take 48 to 72 hours before it expands to size
5. Lauraland 4-Inch Memory Foam Mattress Topper
Besides being larger than the Best Price mattress topper, the queen-size Lauraland memory foam also carries the CertiPUR certification.
Review
This mattress topper is one of the more affordable options, but it is a bit more expensive than the Best Price mattress topper.
- Product Design
This Lauraland mattress topper is much like the Best Price topper, but it has no herbal or active cleaning ingredient infusions.
It does not come with a cover or straps, which means you will have to rely on your bedsheets to keep it in place.
However, it’s good that it also has small ventilator holes poked through both surfaces.
This feature makes the topper more breathable as it reduces excess body heat.
- Product Variations
If a four-inch topper is too thick for your mattress, you might want to consider their two-inch and three-inch options.
The problem is that they might be too big for twin and full-sized beds, as they only come in short queen, queen, king, and California king sizes.
- Cleaning
Vacuum cleaning is the best approach to maintaining this mattress topper.
Aside from removing dust and small particles, it will also remove dust mites lingering near the surface.
For accidental stains, you can do some spot-cleaning with mild soap and a damp towel.
Pros:
- Breathable memory foam
- Reduces trapped body heat
- Increases softness
- Relieves body pains
- One of the more affordable options
- Comes with a three-night risk-free trial
Cons:
- No herbal relaxants or active cleaning agents
- A bit more expensive than the Best Price mattress topper
