That difference affects the feel, fit, and care you should expect. Below, we compare five options by their listed construction, cooling features, certifications, and mattress fit so you can choose the style that suits your bed.

Our Picks: Best 4 Queen Memory Foam Mattress Topper reviews
Best Price Mattress 4-Inch Ventilated Gel Topper: A Straightforward Foam Layer
This topper uses a 4-inch layer of responsive memory foam, making it a simple option if you want to change the feel of your mattress without switching to a mixed-fill pillow top. Its ventilated design is intended to help air move through the foam, while the gel infusion is intended to help reduce trapped body heat.
The foam is CertiPUR-US certified, and the product listing states that it includes a three-year manufacturer’s warranty. The topper arrives compressed and may need 24 to 72 hours to regain its full shape. Expansion time can depend on the room temperature, so give it room and time before judging its final thickness.
Compared with the quilted and shredded-fill options below, this is the most direct choice for shoppers who want a memory foam surface rather than a fluffy pillow-top feel. Keep in mind that a gel infusion and ventilation are design features, not a guarantee that every sleeper will feel cool.
Pros:
- Four inches of responsive memory foam
- Ventilated design and gel infusion
- CertiPUR-US certified foam
- Listed with a three-year manufacturer’s warranty
Cons:
- Needs time to fully expand after unpacking
- A solid foam layer may not suit shoppers seeking a fluffy, quilted surface
Verdict: Choose this Best Price Mattress topper if you want a substantial, conventional foam layer with airflow features and a stated foam certification.
WhatsBedding 4-Inch Gel and Shredded Foam Topper: A Fluffier Mixed-Fill Feel
Rather than using only a single slab of foam, this WhatsBedding topper combines gel memory foam with shredded memory foam inside a breathable cover. The listed design aims to pair a softer, cushioned surface with the support of the shredded fill. Its dot quilting is intended to help keep the filling distributed across the topper.
Four elastic anchor straps are included to help hold it in place. That can be useful if your topper tends to shift as you move in bed, though you should still check that the queen size matches your mattress. The topper is vacuum compressed; the instructions recommend patting it and letting it stand for 24 hours to regain its fluffiness.
This design may appeal if you like the look and feel of a pillow top more than a uniform foam slab. The tradeoff is that it has a different construction from traditional solid memory foam, so don’t assume it will respond or feel exactly like one. The listing does not specify a foam certification or warranty.
Pros:
- Combines gel memory foam and shredded memory foam
- Breathable cover and dot quilting
- Four anchor straps help secure the topper
- Designed for a soft, cushioned feel with support from the fill
Cons:
- Needs time to regain its loft after unpacking
- Does not list a foam certification or warranty in the supplied product details
Verdict: Consider WhatsBedding if you prefer a fluffy, quilted topper with anchor straps over a single piece of solid memory foam.
Best Price Mattress Egg Crate Topper: A Contoured Surface with Lavender Infusion
This 4-inch topper uses egg-crate-shaped memory foam instead of a flat foam surface. The raised contours are designed to increase airflow, and the product listing describes the foam as body-conforming and pressure-relieving. It also includes a lavender infusion, a feature to weigh by scent preference rather than treating it as a guaranteed sleep benefit.
The topper’s responsive suspension is intended to isolate motion, which may be useful when sharing a bed. Its foam is CertiPUR-US certified, and the listing states that it comes with a three-year manufacturer’s warranty. As with any topper, the added height may change how your fitted sheets sit, so check your sheet depth before ordering.
Compared with the ventilated gel model from the same brand, this version relies on its egg-crate shape and lavender infusion rather than a listed gel infusion. The surface shape may not be for everyone, especially if you prefer an even, smooth feel across the bed.
Pros:
- Egg-crate shape is designed to increase airflow
- Body-conforming memory foam
- CertiPUR-US certified foam
- Listed with a three-year manufacturer’s warranty
Cons:
- Contoured surface may feel different from flat foam
- Lavender infusion may not suit shoppers who prefer unscented bedding
Verdict: Pick this model if you want an egg-crate memory foam surface and value the listed certification and warranty.
LIANLAM 4-Inch 2000 GSM Topper: Plush Fill with a Deep Pocket
LIANLAM’s topper combines shredded memory foam with down-alternative fill in a quilted pillow-top style. Its 4-inch profile is designed to provide a plush surface, while the shredded fill differs from the uniform feel of a solid memory foam slab. The listing identifies the fabric as a bamboo-viscose blend and states that it is OEKO-TEX certified.
A deep-pocket skirt is designed to fit mattresses from 8 to 18 inches thick, with reinforced corners intended to help limit shifting. This broad fit range is helpful if your mattress is taller than average, but measuring your mattress—including any existing pad—is still the best way to check compatibility.
The product description makes strong claims about pain relief and support, but comfort is personal, and a topper cannot be counted on to treat back, hip, or joint pain. Compared with the first and third picks, this model emphasizes fluffy fill and a fitted skirt rather than a single piece of certified memory foam. The supplied details do not state a warranty.
Pros:
- Shredded memory foam and down-alternative fill for a pillow-top style
- Deep pocket designed for mattresses 8–18 inches thick
- Reinforced corners are intended to help keep it in place
- Listing states that the fabric is OEKO-TEX certified
Cons:
- Mixed fill will feel different from a solid memory foam layer
- Warranty details are not provided in the supplied product information
Verdict: Choose LIANLAM if you want a plush, fitted pillow-top design and your mattress falls within its stated depth range.
Zalmureta 4-Inch Cooling Pillow-Top Topper: Air Mesh and Shredded Fill
This Zalmureta topper pairs shredded memory foam with down-substitute fill in a quilted, 4-inch pillow-top design. The listed cooling features include cold gel memory foam filling and a 3D air-mesh layer intended to promote air circulation. These are design aims, so they should not be taken as a promise of a particular sleeping temperature.
The elastic pocket is listed as fitting mattresses 6 to 18 inches thick, and diamond quilting is intended to help distribute the fill. The product instructions say the topper is vacuum compressed and should be patted or dried, then left for 24 hours to reach its fullest loft. The supplied product data marks this item as unavailable, so check the Amazon listing before making it your first choice.
Compared with the LIANLAM model, this option also uses shredded foam and a fluffy fill, but it highlights gel filling and air mesh. The listing does not provide a foam certification or warranty in the supplied details. Its stated availability is also a practical drawback if you need a topper soon.
Pros:
- Shredded memory foam and down-substitute fill
- Includes cold gel filling and 3D air mesh
- Deep pocket is listed for mattresses 6–18 inches thick
- Diamond quilting is intended to help keep filling distributed
Cons:
- Supplied product data marks it as unavailable; check the listing
- Needs time to regain its full loft after unpacking
Verdict: Zalmureta may suit shoppers after a fluffy design with airflow features, but confirm it is available and check the listing details before choosing it.
How to Choose a 4-Inch Queen Memory Foam Mattress Topper
Decide Between Solid Foam and Mixed Fill
A solid memory foam topper gives you one continuous foam surface. Egg-crate models add a contoured shape, while pillow-top styles combine shredded foam with a softer fill inside a cover. These constructions can feel quite different, so start with the surface you prefer rather than choosing by thickness alone.
Check the Queen Size and Your Mattress Depth
Confirm that the topper is made for a queen mattress and check any stated pocket-depth range if it has a fitted skirt. Mattress thickness matters for toppers with deep pockets, while strap-based designs may attach differently. Include any mattress pad you plan to keep on the bed when checking the total height.
Think Carefully About Cooling Features
Ventilation, egg-crate shaping, gel infusion, and air mesh are all features intended to support airflow or reduce heat buildup. They do not guarantee that a topper will sleep cool for every person. If you tend to overheat, compare the design details, but remember that your mattress, bedding, room, and personal comfort can also affect how warm you feel.
Look for Relevant Certifications and Warranty Details
If foam certification matters to you, check the exact product listing. The two Best Price Mattress options here state that their foam is CertiPUR-US certified. The LIANLAM listing states that its fabric is OEKO-TEX certified. These refer to different materials, so don’t treat one certification as a substitute for the other. Also check the warranty terms and what they cover before buying.
Plan for Expansion and Setup
Compressed foam and pillow-top toppers may need time to regain their shape after opening. Follow the product’s setup instructions and allow the stated expansion time before deciding whether the topper feels or looks right. For these picks, the listed guidance ranges from 24 hours to 24–72 hours, depending on the product.
Match the Topper to the Problem You Want to Solve
A topper can change the feel of your sleep surface, but it cannot repair a sagging or damaged mattress. Consider whether you want a softer layer, a more contoured feel, or a fluffy pillow-top surface. Claims about pain relief are not a substitute for medical advice, and no topper can promise to resolve back, hip, or joint discomfort.
Frequently Asked Questions
Is a 4-inch topper a good choice for every mattress?
Not necessarily. Four inches adds a noticeable layer, which may suit someone looking to change a mattress’s feel substantially. It can also raise the bed surface and affect fitted-sheet fit. Check your mattress condition and sheet depth before ordering.
Are all of these toppers made from solid memory foam?
No. The Best Price Mattress options use memory foam, including one with an egg-crate shape. WhatsBedding, LIANLAM, and Zalmureta describe mixed constructions that include shredded memory foam and additional fill.
Can a gel or ventilated topper guarantee cooler sleep?
No. Gel infusion, ventilation, and air mesh are features intended to help with airflow or heat buildup, but they cannot guarantee a cool feel for every sleeper. Your bedding, room conditions, and personal preferences also matter.
How long should I wait for a compressed topper to expand?
Follow the instructions for the specific product. The Best Price Mattress ventilated topper lists 24 to 72 hours, while the WhatsBedding and Zalmureta listings recommend about 24 hours for the fill to regain loft.
Which options list a foam certification?
The two Best Price Mattress products state that their foam is CertiPUR-US certified. The LIANLAM listing states that its fabric is OEKO-TEX certified, which is a different material claim. Check the current listing for complete details.
Can a mattress topper relieve back pain?
A topper can change the cushioning and feel of your bed, but comfort varies from person to person. Product claims about pain relief should not be treated as a medical guarantee. If pain continues or is severe, speak with a health professional.
Which topper is best if I want one that stays in place?
WhatsBedding lists four anchor straps, while LIANLAM and Zalmureta describe elastic deep-pocket skirts. Check the attachment style and mattress dimensions to decide which is most likely to fit your setup.
Final Recommendation
For a straightforward queen-size foam layer with a ventilated design, gel infusion, CertiPUR-US certification, and a stated warranty, the Best Price Mattress 4-inch ventilated topper is the clearest all-around choice in this group. If you prefer a fluffy pillow-top feel, compare the mixed-fill options and pay close attention to mattress fit. Before ordering, confirm the size, setup instructions, certification details, warranty, and availability on the product listing.
