Nest Bedding Natural Hybrid Latex

Nest Bedding Natural Hybrid Latex

Best mattress features
  • Breathable organic cotton and Joma wool knit cover wrapped around a conforming pillowtop.

  • Mattress is OEKO-TEX® Standard 100 certified and made in compliance with USA safety standards.

Nest Bedding’s Natural Hybrid Mattress can withstand up to 800 pounds and has a 12-inch profile. The mattress comes with three firmness levels: medium, firm, plush. It’s also OEKO-TEX® Standard 100 certified and USA-made.

The organic cotton and Joma wool knit cover stretches to encourage airflow and wick away heat. The cover is quilted into 1.5 inches of Eco-Flex Quilting Foam to create a pillow top. The foam contours to the sleeper, relieving pressure points and pain.

The second comfort layer is 3 inches of breathable Dunlop Latex, offering a firm, bouncy feel. The layer contours to the sleeper, pushing up to support the hips and shoulder.

The second layer, 1-inch poly-foam, transitions between the soft and firm layers, preventing the sleeper from hitting the base layer.

Below, 6 inches of pocketed coils provide support and bounce. The coils isolate motion to prevent sleep disturbances when a sleep partner turns over in bed.

The 1-inch high-density polyurethane base layer prevents sagging and extends the mattress’s lifespan by maintaining the bed’s shape.

Nest Beddings lifetime warranty states Nest Bedding repairs and replaces mattresses with visible indentations greater than 1 inch, physical flaws in the cover zipper, and defective covers. Keep in mind the warranty only covers defects— not regular wear and tear.

Every Nest Bedding mattress comes with a 100-night trial where you may try the bed and return it if it doesn’t meet your sleep needs.

What Is A Full Mattress?

A full-size mattress measures 54 inches by 75 inches. It’s 14 inches wider than a twin mattress, and 6 inches narrower and 5 inches shorter than a queen size mattress. It’s a great size bed for teenagers or college students who like to spread out but have smaller bedrooms.

Buying Guide: How to Pick the Best Full-Size Mattress

While knowing what mattress size you want is important, there are several other decisions you need to make. Consider these features before choosing your best mattress.

Budget

Full Mattresses are a cheap alternative for young single adults who are ready to graduate from the twin XL but can’t afford a queen bed. We recommend setting a budget between $400 and $2000 for a high-quality full-size mattress. On average, people spend around $1000 for a full-size bed.

Firmness

Mattress firmness is rated on a scale of 1 to 10: soft (1 to 2), medium-soft (3 to 4), medium (5), medium-firm (6 to 8), and firm (9 to 10).

Getting the right firmness can elevate your sleep quality; however, firmness is subjective. The right firmness for you can cause pain for someone else. You can estimate your perfect firmness by learning about your sleep position and body type.

Body Type

A smaller person needs a softer mattress than a larger-statured sleeper. Lighter individuals don’t weigh enough to sink into the materials, so they need plushy beds to relieve pressure.

Heavier individuals can suffer spinal misalignment on a soft mattress as the hips are heavy and can bend into the materials. A firm mattress offers enough support to the hips to prevent sinkage while still relieving pressure.

Sleep Position

The best mattresses for side sleepers are soft to medium in firmness. Softer beds alleviate pressure points built up of the sleeper’s shoulders and hips.

Comfortable mattresses for back sleepers can range from soft to firm, they just need to be supportive enough to promote healthy spinal alignment.

If you’re looking for a mattress for stomach sleeping, you’ll need something firm. Stomach sleepers overextend their back muscles, ligaments, tendons, and spine by laying on their fronts. Overextending the back muscles for long periods can lead to sciatica, herniated discs, and osteoarthritis.

We suggest stomach sleepers switch to side sleeping to avoid chronic pain issues. If changing preferred sleep positions isn’t an option, stomach sleepers can invest in a medium-firm to firm mattress to preserve the spine’s natural curvature. We recommend sleeping without a head pillow and, instead, placing that pillow under the hips to promote spinal alignment.

Mattress Materials

You should also decide what type of mattress you want. Latex, memory foam, hybrid, and innerspring mattresses have different advantages and drawbacks. One mattress type may cater to your sleep needs better than others.

Memory Foam Mattress

Memory foam offers a hug-like conformability to alleviate pressure points and pain. The same contouring qualities absorb motion on impact, preventing motion from transferring across the mattress’s surface. Memory foam’s ability to isolate motion allows you to get out of bed or switch sleep positions without disturbing a sleeping partner.

Some users find memory foam sleeps hot; however, many manufacturers use conductive material infusions, such as copper, graphite, and gel, to pull heat from the sleeper and promote cool nights.

Memory foam mattresses last an average of eight to ten years.

Innerspring Mattress

Innerspring mattresses are constructed with coil cores and a thin comfort layer made from polyester, cotton, or wool. Some innerspring beds are built with pillow and Euro tops for a plush feel.

An innerspring bed offers great support. The coil systems promote breathability to keep the sleeper cool, although these beds attract allergens, dust, and debris, which can lead to respiratory irritations.

A coil mattress can last an average of 6 to 7 years.

Latex Mattress

Latex mattresses are the most supportive type of bed on the market. Latex beds are comparable to memory foam mattresses in conformability.

Natural latex mattresses are the longest lasting—20 years—although we suggest retiring a natural latex bed after 10 years of use for hygienic reasons. Natural latex is manufactured from rubber tree sap and has hypoallergenic and antimicrobial properties.

Dunlop-processed latex is durable and dense. Talalay Latex is also made with rubber tree sap, although chemical additives are used to produce a bouncy and light foam, making it more expensive than Dunlop.

Synthetic latex is manufactured with chemical compounds and mimics latex properties. This type of latex is safe for latex allergy sufferers but doesn’t possess the antimicrobial properties of natural latex and lasts only six years.

Blended latex is a combination of synthetic and natural latex. It doesn’t have strong antimicrobial qualities, but the mattress can last up to 10 years.

We recommend against purchasing synthetic latex as the materials may contain harmful additives. If you decide on synthetic latex materials, we suggest making sure the mattress has a CertiPUR-US® certification.

Hybrid Mattress

Hybrid mattresses are built with coil cores and thick memory foam or latex foam comfort layers. These beds feature strong edge support. They possess better conformability than coil mattresses, and the coil core encourages airflow to keep the sleeper cool.

Hybrids have a lifespan of 6 to 7 years.

Sleep Trials, Return Policies, and Warranties

Sleep trials, return policies, and warranties protect the customer against keeping a defective mattress or a bed they do not want.

Sleep trial

Sleep trials offer an extended time period for the sleeper to try the mattress in their home without financial risk. If the bed doesn’t meet their expectations, they can return it.

We recommend looking for a risk-free trial that includes free returns.

Return Policy

The return policy outlines the customer and company’s responsibilities when a return is initiated. We suggest looking for a return policy where the company claims full financial responsibility, including restocking, donation, and recycling fees.

Warranty

The warranty ensures the owner doesn’t get stuck with a defective mattress. As long as the damage isn’t incurred due to mishandling and misuse, the company should return or repair the mattress.

Most mattress companies do not repair or replace a bed until sagging is greater than one inch. Foam cracking and flawed covers are often covered, but regular wear and tear is not.

FAQs

What is the top-rated mattress for 2021?

We recommend the Amerisleep AS3 or the Zoma Mattress as they are constructed with quality materials and provide a balance of comfort and support. These beds can support most sleeping positions and body types, making them extremely versatile. Both of these mattresses are also built to last. With a stable support base, these beds will keep you resting in a safe, comfortable sleep position throughout many years of use.

Do I need a box spring?

All mattresses need a sturdy base to support a sleeper properly. Some beds require their foundations to meet certain criteria. For example, the best foundation for a memory foam mattress is a solid bed frame with slats no more than 3 inches apart, while innerspring and hybrid beds are well supported with a basic box spring. However, box springs do not provide support to the mattress, they simply add height.

How do I fix a sagging mattress?

If your current mattress has sagging and indention, it is likely time to replace it. However, if you are not in a possible to purchase a new bed, you can use a memory foam topper to change the feel of the bed. In most cases, a medium to medium-firm topper can create a more stable, even sleep surface to keep you comfortable and supported.

How can I get rid of my old mattress?

Some mattress companies dispose of your old mattress when they deliver your new bed. These companies often work with local charities and recycling centers. You can also arrange for your mattress to be donated if it is still is good condition. A local recycling company can also pick up your mattress and recycle it for you.

Should I get a pillow top mattress?

Pillow top mattresses are traditional innerspring beds with a thicker foam comfort layer on top. While we don’t recommend innerspring beds, the added foam layer can help cushion and protect the pressure points when side sleeping. However, be sure the foam topper is at least 2 to 3 inches, this will create a thick barrier between you and the spring coil base.

Conclusion

Everyone’s sleep needs are unique, so consider your sleep position and body type before you choose a mattress. For instance, your perfect mattress can cause someone else back pain. If you sleep with a partner, bring them along so you can consider their preferences as you mattress shop.
