The egg crate upgrade
Our egg crate topper is GOLS certified organic Dunlop latex, cut into a peak-and-valley surface. The peaks spread your weight and cushion pressure points, while the Dunlop latex underneath keeps you supported.
Pro tip: add a mattress topper cover to keep your topper clean and make care easier. We can install it for you before it ships.

The peaks give under your shoulders and hips and spread your weight. The channels and pinholes between them keep air moving, so it sleeps cool.

Made from the sap of organically grown rubber trees. Also tested by OEKO-TEX, eco-INSTITUT and LGA for harmful substances.

Dunlop latex is responsive and resilient, so it springs back instead of sagging. With good care, expect 5 to 10 years of use.

Two thicknesses
Pick 1.4 or 2.4 inches, depending on how much cushioning you want. The drawings are to scale.
Light cushioning on a mattress that is still supportive. Adds comfort without changing the feel too much.
Deeper peaks for more pressure relief. A good choice to soften a mattress that feels too firm.
The peaks are cut from a thicker latex base, so height varies a little across the surface. The 2.4-inch topper usually peaks at about 2 inches, and the 1.4-inch at about 1.2 inches. This is normal for egg crate cutting and doesn't change how it feels or performs.
Two firmness levels
Pick by how you sleep and what you weigh.
Plush and cushioning. A great pick if you want to soften a mattress that feels too firm.
A balance of soft and firm, with more support under the peaks.

Care
Pro tip: a washable cover makes care much easier. Protect your topper with a topper cover, a fitted sheet or a waterproof mattress protector. These fit best:
Egg crate tip: lay it bumpy side up, over any mattress pad and under your fitted sheet.
It isn't machine washable. Dab the spot with a sponge, water and a mild detergent, then let it air-dry.
Long exposure to direct sunlight, or heat above 85°F, breaks latex down and shortens its life.
Latex can tear if it's pulled hard. Unpack it gently and lift it onto your mattress rather than dragging it.
Vacuum the surface about once a month, avoid eating and drinking on it, and spot-clean spills right away.
Yes, for most people. The peaks cushion pressure points like your shoulders and hips, and the Dunlop latex underneath keeps your spine supported, so you wake up less stiff.
The peak-and-valley shape gives more contouring and pressure relief than a flat surface. The channels between the peaks and the pinholes through the latex also let air flow, so it sleeps cooler.
Egg crate mattress toppers are good for side sleepers. The sleeping position requires a conforming surface that doesn't put any pressure on your sides or hips. Along with this aspect, side sleepers also require a firm, supportive surface to hold up their spinal alignment. Egg crate mattress toppers can do both of these things very well.
Ours comes in 1.4 and 2.4 inches. Choose 1.4 inches for light cushioning on a mattress that is still supportive, or 2.4 inches for more cushioning and pressure relief, for example to soften a mattress that feels too firm.
The peaks are cut from a thicker base, so the 2.4-inch topper usually peaks at about 2 inches and the 1.4-inch at about 1.2 inches.
The mattress topper size that you choose should be similar to your existing mattress size. For example, choose the twin-size egg crate topper if you have a twin bed, the queen-size if you have a queen bed, and so forth.
When toddlers outgrow their cribs, twin beds, usually in the form of a single or bunk, are suitable for them. The twin-size egg crate topper is for the twin bed. It can also be a great budget option for single adults, preferably those with a height of 5'5" or less. The twin-size bed dimensions are 38′′ x 75′′.
As you would've guessed, a twin XL is the extra large version of the twin size. It is suitable for single sleepers, usually at the height of 6'3" or less, who can't fit into a twin bed. Adults and growing children can both make use of this. The twin XL-size bed dimensions are 38′′ x 80′′.
A full-size is for those who desire something with more space than a twin. Though it isn't as large as the queen, it is a luxurious choice for single sleepers. Couples who are willing to compromise can make use of this as a budget bed. It can also be suitable for the guest room or someone with pets or children. The full-size bed dimensions are 54" x 75".
A queen size is an optimal choice for couples and single people who are taller than 6 feet. For lone occupants, it is more than adequate, but for couples, it might be just perfect. This size will also work well for guest rooms and compact master bedrooms. The queen-size bed dimensions are 60" x 80".
The king size is the one to rule them all. An entire family of four could fit in comfortably, along with any pets. It's more than enough for singles as well as couples. But make sure you have enough space in your room to fit it in (somewhere around 12 x 12 square feet should be enough). The king-size bed dimensions are 76" x 80".
The California king size is wider than the standard king but is slightly narrower in length. It's great for tall individuals and couples who need more legroom. It's also a good option if you have a narrow bedroom that cannot accommodate a king-size. The California king-size bed dimensions are 72" x 84".
An average mattress topper usually has a flat surface, while an egg crate mattress topper has an intricate design in the structure of an egg crate. This peak and valley pattern aims to provide the user with a beyond-the-norm experience.
Pros: They're great at relieving pressure and tension from the body. They can also revamp your whole mattress experience by enhancing its benefits.
Cons: A lower-quality egg crate topper may end up causing spinal misalignment, which causes pain in the morning. Budget quality toppers can also end up being a huge waste of money.
Not all egg crate foam toppers are toxic. It depends on the material used and whether any chemicals or retardants are involved in the manufacturing. For instance, Turmerry's organic latex egg crate toppers are deemed harmless to sleepers, as they are tested for harmful substances by Oeko-Tex Standard 100.
The egg crate should go over the mattress pad, with the bumpy side of the egg crate topper facing up toward the ceiling. This part of the topper is essential for effectively providing pressure-relieving properties. Placing it this way also improves the breathability and cooling of the topper.
Some egg crate foam toppers can be machine washed, while others, such as those made of natural latex, cannot be cleansed similarly. Instead, they require spot cleaning and vacuuming to maintain the foam's integrity.
The standard method of drying egg crate foam toppers is by letting them air out. Leave it naked in a well-ventilated space, away from direct sunlight, and only put it to use once the traces of moisture have entirely vanished.
A well-maintained egg crate latex topper lasts 5 to 10 years. Once the topper shows signs of deterioration, such as body impressions refusing to go away, it is time to say goodbye.
The textured side (or bumpy side) of the egg crate should face up so that it makes contact with your body. This will help you get the most benefit from the topper in terms of comfort and support. Now encase it with a fitted sheet, and make sure the sheet doesn't sit too tightly. The egg crate foam will create a supportive yet comfortable mattress surface that will help you get a good night's sleep.
The latex used to make Turmerry mattress toppers comes from organically grown rubber trees. These trees are sustainable crops that contribute to preserving the global carbon balance in the atmosphere.
The rubber trees don't need to be cut down for the latex, meaning the environment remains intact and undamaged. The organic latex content is >95%, and 5% chemical agents are used to make the foam from the rubber sap. The resulting product is Oeko-Tex, eco-INSTITUT, and LGA certified.
Dunlop processing, an environmentally friendly and resource-conserving process, is used to create the toppers. Dunlop latex makes for a robust and firm foam, giving you the necessary support you desire.
One thing to keep in mind is that this is an expensive mattress topper, but it's worth noting that it's made from natural materials, so there are no harsh chemical smells or synthetic fillers that could be harmful. In addition, it's designed to be suitable for every sleeping position and can benefit anyone who uses it. Despite the high cost, the many benefits it provides make it a worthwhile investment. Some of its unique features include:
Breathable and Cooling through Increased Air Circulation
Durable, Quiet, Springy, and Responsive
Conforms well to the body
Body support, Enhanced weight distribution, and Pressure relief
Sustainable and Eco-friendly
Polyurethane, a polymer, is used to make memory foam mattress toppers. Despite being created synthetically in laboratories, this material can decompose, making it a more environmentally friendly alternative to plastic. We do not sell memory foam toppers, but if you buy one, make sure to buy from reputed brands.
Also, ensure that the memory foam mattress topper is Certipur US certified or has other well-known certificates to show it is harmless for humans.
Memory foam isn't just polyurethane, though. It is a mixture of polyurethane and other chemicals, such as polyols, diisocyanates, and blowing agents. When buying a memory foam mattress topper, be wary of cheap ones. Most companies have stopped using harmful chemicals that were predominant earlier, such as toluene, formaldehyde, and CFC, yet some may still use them to cost-cut.
Synthetic additives in the memory foam recipe are one of the many causes of reported off-gassings (an unpleasant smell emitted by VOCs). Not all is doom and gloom with memory foam, though. Their pros include:
Soft and Sinking
Pain relief and Body Support
Molds to the body shape
Polyester, a synthetic fiber made from petroleum, is the core material of polyester mattress toppers. It is the cheapest material available to be used in mattress topper manufacturing. Unfortunately, it is also the least supportive.
On the front of eco-friendliness, polyester isn't sustainable or effective. It isn't biodegradable, can shed toxic microfibers, and is energy-intensive to produce. Furthermore, it requires non-renewable resources such as oil for production and contributes to the emission of CO2.
Polyester mattress toppers are an excellent substitute for those who love the feel of a down or down alternative mattress topper but are allergic to them. Yet, though they're cheap, they aren't very durable. On arrival, they will be fluffy and soft. But after a short time, they tend to compress and break down, providing little to no cushioning. The benefits of polyester toppers include:
Soft and Fluffy
Cheap and Inexpensive
Odorless
Light Weight
Feather mattress toppers, also known as down mattress toppers, are produced with feathers or down. Naturally sourced from the soft undercoats of ducks and geese, they are undoubtedly eco-friendly and biodegradable.
Featherbeds are usually very soft and fluffy. The lack of firmness means lessened support for the body, neck, and spine. When buying a featherbed, buy it for its comfort. Do not expect much in the area of body alignment or pain relief.
An allergy to feathers is a common deterrent when choosing a feather mattress topper. They are also noisy, which could be a problem for people with a heightened sense of hearing. Furthermore, vegans or animal rights activists may not take kindly to the procurement of the feathers, prompting them to look for an alternative mattress topper. Benefits of featherbeds include:
Soft and Fluffy
No heat retention
No inhibition of movement while sleeping
Cheaper alternative
Produced with natural wool, the fiber obtained from the fleece of sheep, lambs, and goats, wool mattress toppers are eco-friendly but can be hard to get your hands on.
Additionally, they are more expensive than their counterparts and emit an odor similar to that of sheep. You will find that they provide extra cushioning. Benefits include:
Soft and Extra Cushion
Doesn't hinder movement
Durable
Cooling during summer
Warming during winter
A latex mattress topper is usually better than memory foam toppers for back pain. A memory foam mattress topper is synthetically manufactured to specifically provide a higher level of contouring. On the other side of memory foam is latex, which is naturally obtained and organically manufactured to provide a balance between contouring and support.
For back pain relief, support to the spine is as necessary as contouring to the body. A memory foam mattress topper may not be as supportive as you need it to be, as memory foam has a tendency to sink. Under the influence of a sinking memory foam mattress topper, your spine may become misaligned, worsening your back pain.
Traditional memory foam mattress topper types are also susceptible to heat retention, less bounce and response, VOC off-gassing, and other issues associated with synthetic products. The heat retention, bounce, and response issues could be mitigated with a cooling gel-infused memory foam mattress topper, but VOCs will still remain an issue.
A natural latex mattress topper excels over a memory foam mattress topper in terms of cooling, bounce, response, firm support, and no VOCs. It also finds a proper balance between support, pressure relief, and contouring, helping foster a perfect healing environment for back pain. For further assurance, you can check out this study that compares latex against foam material.
A mattress pad is a thin layer of material, usually 1-2 inches thick, used to increase the comfort offered by a mattress while also protecting it from liquid spills, impurities, etc. A mattress topper is a thicker layer of material than a mattress pad, often 2-4 inches thick, used to completely revamp the comfort and support offered by a mattress.
A mattress pad doesn't significantly change the pressure relief, support, or contouring offered by your mattress. Cotton, polyester, and wool are popular materials used for mattress pad manufacturing.
A mattress topper has the ability to revive old mattresses back to life, soften up a firm mattress, or firm up a soft mattress. Unlike a mattress pad, a mattress topper can better evenly distribute body weight and offer greater pressure point relief. With these benefits can also come an increase in price. Memory foam and latex are the most common materials used for mattress topper manufacturing.
A latex mattress topper can certainly be put on top of a memory foam mattress. Memory foam mattresses may have a tendency to sink, pulling you down with them. Placing a firmer material, such as latex, on top of memory foam can help mitigate this issue while making the bed more supportive.
Placing other mattress topper types, such as a memory foam mattress topper, may only contribute further to the sinkage. Opt for a memory foam mattress topper only if you seek more of what your memory foam mattress offers.
The adjustment period to an egg crate foam mattress topper varies from person to person. Usually, it may take a few nights to a couple of weeks for your body to fully adapt to the new surface. Some people might find it comfortable right away, while others may need more time to get used to the different feel and support it offers.
Comparing a latex egg crate mattress topper to an egg crate memory foam topper depends on individual preferences and needs. Latex toppers are known for their resilience, natural materials, and hypoallergenic properties, making them a good choice for those with allergies or sensitivity to chemicals. An egg crate memory foam mattress topper, on the other hand, conforms closely to the body's contours, providing excellent pressure relief and comfort.
These are approximate weights of the topper itself, without the box, and can vary by a pound or two.
1.4" Soft: Twin 7 lbs, Twin XL 7 lbs, Full 10 lbs, Queen 11 lbs, King and Cal King 14 lbs
1.4" Medium: Twin 7 lbs, Twin XL 8 lbs, Full 11 lbs, Queen 13 lbs, King and Cal King 17 lbs
2.4" Soft: Twin 10 lbs, Twin XL 11 lbs, Full 15 lbs, Queen 17 lbs, King and Cal King 21 lbs
2.4" Medium: Twin 12 lbs, Twin XL 12 lbs, Full 16 lbs, Queen 19 lbs, King and Cal King 25 lbs
No. Unlike light foam or fiber toppers, natural latex is heavy and its surface grips the mattress, so it stays in place under a fitted sheet without straps.
For the best fit, choose the same size as your mattress and use a fitted sheet with pockets deep enough for the mattress and the topper together.
Most customers unpack it and sleep on it the same day. Natural latex can have a faint, sweet scent right out of the box from being sealed for shipping. It isn't the chemical smell of memory foam.
If you're sensitive to smells, stand it up in an airy room for a day or two.
No. The egg crate topper is one solid piece across its full width, even King and Cal King, so there is no seam down the middle. Our topper covers have no middle seam either.
Yes. The topper bends with an adjustable base. You can also use it on a platform bed or futon frame; for the most comfort with no mattress underneath, choose the 2.4-inch topper.
