Our experience with Saatva Classic Mattress
Saatva’s mattresses are made with eco-friendly materials that are not only good for you but for the environment as well. If you are someone who lives an eco-conscious lifestyle, then you must give this mattress a shot.
The Saatva Classic mattress comes in three firmness options, making it suitable for all sleeper types. The mattress offers patented spine zone technology to enhance back support. People who suffer from chronic back pain or even athletes will also benefit from this mattress. The pillow-top helps recreate a luxury hotel experience and make you feel comfortable.
Firmness
Saatva offers 3 firmness levels under Classic model:
- Plush soft
- Luxury firm
- Firm
The Saavta Classic’s plush soft variant offers deep body hugging feel. This variant is more suitable for strict side sleepers as well as some combination sleepers. If you are a combo sleeper and like a cuddly mattress, this mattress is great pick for you.
The Luxury firm variant of Saatva Classic is designed to replicate the comfort luxury hotels offer. This variant is medium firm sitting at 5-6/10 on a mattress firmness scale. Light to average weight stomach and back sleepers will find this variant most comfortable .
Having said that, you should know that mattress firmness is subjective to weight, height, and sleeping position. What is firm for you might be a bit soft for a heavier individual. If you are prefer memory foam, then we wouldn’t recommend that you buy Puffy Royal mattress instead.
Last but not the least – the Firm variant. We can safely say that it is not as firm as you might think it would be. The pillow-top keeps the mattress cushy and comfortable. The support comes from the base and the upper layers compliment it by offering a comfortable sleep environment. You don’t feel like you are sleeping on an extra-firm mattress but a soft mattress with great support. The firm variant is a great option for strict stomach and back sleepers who like cuddly feel as well.
Construction
The Saatva Classic mattress comes in two heights – 11.5″ and 14.5″. The mattress is comprised of five layers:
- Pillow-top layer
- Polyfoam layer
- Pocketed coil layer
- Memory foam layer
- Support base layer
The top most layer of the mattress is a 3″ thick euro pillow-top. The plush layer is covered in breathable and hypoallergenic cotton treated with Saatva’s exclusive Guardian botanical antimicrobial treatment. If you are someone who is prone to allergies, this mattress will keep you away from year-long allergies.
A high density polyfoam layer sits under the pillow-top layer surrounding the perimeter of the mattress reinforcing edge support. This prevents the mattress from undue sagging as well as enhances responsiveness of the mattress. If you are someone who suffers from arthritis or fragile knees, then this mattress is a great option for you.
The first layer of pocketed coils is an 884 proprietary lumber zone® made from 14.5-guage recycled steel. These coils help the sleeper move around easily and adds a more responsive feel to the mattress.
Under the first layer of pocketed coils sits a high density memory foam made of CertiPur-US certified memory foam acting as a transition layer. The foam and coils layers work seamlessly together to provide the ultimate pressure relief.
The Saatva Classic’s base unit is made up of 416 tempered steel, 13 gauge coils giving the mattress maximum support. The coil on coil system works to help regulate temperature throughout the mattress at all times. A hybrid mattress helps prevent mold and mildew as well.
Sizes
The Saatva Classic mattress comes in 8 different mattress sizes including split California king mattress. It measures 11.5″ or 14.5″ and is compatible with most bed bases and bed frames, including an adjustable bed base.

#2. Natural Form Refresh Mattress
Check Current Price | Best for All Sleeper Types | Review
Pros:
- All sleeper types
- Great for people suffering from back pain
- Adjustable firmness levels
- Sleeps cool
Cons:
- Might be too soft for some people
- Slight off-gassing
Who should buy Natural Form Refresh Mattress
- People who want a thick mattress
- People suffering from chronic back pain
- All sleeper types
- Couples with the similar sleeping styles
Our experience with Natural Form Refresh Mattress
If you want a thicker mattress, then you should try Natural Form’s Refresh mattress. The Refresh mattress is an award-winning mattress with adjustable firmness levels. It can cater to all sleeper types – stomach, back, side, or combination because of its adjustable firmness. The mattress has great motion isolation and a soft feel. Couples with similar sleeping styles will also find this mattress comfortable and practical.
Firmness
The firmness level of the Refresh mattress can vary between 5-8 depending upon how you adjust it. We found the Refresh mattress more supportive compared to Natural Form’s other mattresses.
Strict stomach sleepers might find the Refresh mattress a bit softer compared to what they are accustomed to. Soft mattresses can cause the midsection to sink into the mattress resulting in back pain. Strict stomach sleepers should ideally look for a more firm mattress like Amerisleep’s AS2.
I felt well-supported on the mattress as I am a combination sleeper. Heavier sleepers in particular will find ample support because of the significant amount of air pods in the mattress. The exclusive air pods technology enhances support and pressure relief for sleepers using the Refresh mattress. If you have been suffering from back pain for a long time, the mattress might be a solid choice for you.
The mattress offers reasonable motion isolation making it suitable for couples with restless partners or fidgety pets. The mattress is neither too firm not soft offering best bits of both the worlds.
Construction
The Refresh mattress is an 11″ tall mattress and consists of 4 layers:
- Mattress cover
- Comfort layer
- Air pod system
- Firmness control base
The Natural Form’s Refresh mattress is encased in Australian natural Merino wool. This wool is not only naturally fire retardant but also proven to be temperature regulating. Below the cover lays a comfort layer that is composed of a hybrid foam blend. This foam is more responsive and firm compared to memory foam.
The Refresh mattress’ air pod system has a capacity to house up to 80 pods on each side depending on the mattress size. The Refresh model of Natural Form carries 10 times more air pods compared to the Garden mattress. The technology of air pods is patented by the Natural Form and is only available in their mattresses.
The sleeper manually controls the air pods through external dual-sided dials. You can set the firmness level that is just right for you. If you prefer a medium-firm mattress like myself, you can twist the dial on the mattress and adjust the firmness. However, Natural Form recommends to keep the bed on its ‘optimum setting’. This setting actually conforms to your body weight and shape. They recommend to keep this setting for at least the initial two weeks to reflect the correct volume and pressure to displace your body weight.
The air pod system is encased in a base that keeps them and upper layers of the mattress intact. This base also helps make the mattress a bit more sturdier and stable.
Sizes
The Refresh mattresses are available in 9 sizes including split king and split California king mattress. The mattress is 11″ thick and compatible with most bed bases, bed frames and bases but Natural Form recommends that it works best with adjustable beds.
- Twin XL
- Full

- Queen
- Olympic Queen

Durability
The Refresh mattress comes with a 100-night sleep trial and is backed by a 10-year warranty. The mattresses are shipped full-sized and Natural Form offers an in-house setup and delivery that is similar to white glove delivery for a nominal fee.

Who should buy the Plushbed’s Botanical Bliss Mattress?
- People suffering from chronic back pain
- Organic mattress lovers
- Back and stomach sleepers
- People suffering from allergies
Our experience with the Plushbeds Botanical Bliss Mattress
People who have adopted an organic lifestyle must consider Plushbeds Botanical Bliss mattress for an all natural bed. The materials used in making this mattress are GOTS-certified organic materials from top to bottom.
The all-latex mattress is highly recommended by orthopedic specialists and chiropractors for to people suffering from chronic back pain for a long time. It comes with three firmness options and is suitable for people who sleep on their backs or stomachs.
Firmness
The Plushbeds Botanical Bliss mattress comes in two firmness options:
- Medium
- Medium-firm
You can choose from three different thickness options – 9″, 10″, 12″. The medium variant is 5-6/10 on a mattress firmness scale. The medium-firm variant easily gets a 7-8/10 on a mattress firmness scale. Both the models are all-latex and devoid of any carcinogenic adhesives, chemicals, toxins, fillers or dyes.
The mattress is supportive and responsive for back and stomach sleepers. We found the mattress helps provide good pressure relief for the shoulders and hips. The support coming from the firmness of the mattress also helps sleepers recover from back pain.
Strict side sleepers must opt for something like Layla mattresses as Botanical Bliss is too firm for them. If you are a lightweight sleeper then you should choose medium-firm variant of the Botanical Bliss. However, if you weigh between 130-230 lbs., then we recommend choosing the firm variant for support and pressure relief.
Construction
The Plushbed’s Botanical Bliss mattress can be 9, 10, or 12 inches tall mattress and consists of 3 layers:
- Mattress cover
- Comfort layer
- Core layer
Botanical Bliss mattress comes with a cotton cover that is GOTS certified and 100% organic. The cotton mattress cover is same in all thickness variants.
The comfort layer of the Botanical Bliss is made up of 2″ thick natural talalay latex in 9″ and 12″ variants and 3″ in 10″ thick mattress.

#4. Brooklyn Bedding Sedona Mattress
Check Current Price | Best for People with Back Pain
Pros:
- Great motion isolation
- Sleeps cool
- Comfortably soft
- Suitable for strict side sleepers
Cons:
- Weak edge support
- Not suitable for heavy set sleepers
Who should buy Brooklyn Bedding Sedona Mattress?
- People who prefer soft mattresses
- Light and average weight sleepers
- People suffering from shoulder and hip pain
- Couples with different sleeping styles
Our experience with Brooklyn Bedding Sedona Mattress
The Brooklyn Bedding Sedona is a hybrid mattress that’s skews towards the softer side. The mattress is more suitable for strict side sleepers as it offers a soft sleeping surface which reduces pressure buildup.
The “pillow top” feature of the mattress and soft response memory foam layers makes it great for low motion transfer. Strict stomach or back sleepers should ideally opt for a firm mattress as it helps in spinal alignment. The minimal motion transfer makes it a great choice for couples with different sleeping styles as well.
Firmness
We found the Sedona mattress to be a 5/10 on a mattress firmness scale confirming it be a medium-soft mattress. Light-to-average-weight side sleepers will find this mattress comfortable as their shoulders and hips will find just about right ‘sink’ into the mattress. However, heavy weight side sleepers will build pressure on their shoulders and hips as they might sink in a bit too much into the mattress.
We were not impressed by the edge support of the mattress while trying out the Brooklyn Bedding Sedona mattress. If you are a sleep close to the edge of the mattress this isn’t the one for you.
The Sedona mattress has a great motion isolation capability making it an excellent pick for couples looking for a soft mattress. If your partner tosses and turns a lot or if you have a pet, you might want to give this mattress a try.
Construction
The construction of the Brooklyn Bedding Sedona mattress is quite extensive. The mattress is 10″ thick and includes 6 layers:
- Top layer
- Memory foam layer
- Memory foam layer (Dense)
- Transition foam layer
- Support layer
- Base layer
The Brooklyn Bedding Sedona mattress has a quilted memory foam cover that is made up of a patented phase-change material. The cooling panel used for quilting helps regulate temperature and you sleep cool.
The first two layers are a 2″ thick higher-density memory foam and a 1″ layer of proprietary hyper-dense slow-response memory foam – both of which are gel-infused. These layers add response and comfort for the sleeper and also help the mattress stay cool.
A transition layer of 1″ high-density foam encases the individually wrapped 8″ coil system base of up to 1,032 Ascension X® coils. The coil system provides excellent motion transfer and support.
The Sedona mattress has one inch thick high-density base that adds durability to the mattress while reinforcing individually encased coils as they compress.
Sizes
The Sedona mattresses are available in 9 sizes including split California king. The mattress is 14″ thick and is compatible with most bed bases, bed frames and foundations, including an adjustable bed base.
- Twin
- Twin XL
- Full

#5. Latex for Less Mattress
Check Current Price | Best Mattress without Coils
Pros:
- 100% natural latex
- Flippable mattress
- Natural wool fire barrier
- Sleeps cool
Cons:
- Not as supportive as innerspring mattress
- Less edge support
Who should buy Latex for Less Mattress
- Hot sleepers
- All sleeper types
- Light to average weight users
- People who can’t decide between 2 firmness options
Our experience with Latex for Less Mattress
Latex for Less is an all-latex mattress without a coil base. The mattress is made out of 100% organic latex and is flippable offering double firmness options – firm and medium. Since it is a dual-sided mattress, it can cater to a range of sleepers – stomach, side, combination, and back. The mattress might not be supportive enough for heavier individuals as they need a bit more firm surface for pressure relief.
Firmness
Latex for Less mattress is a reversible mattress with two firmness options: medium and firm. The firm side can be easily rated as a 7/10, and soft side a 5/10 on a mattress firmness scale.
If you are a combination or stomach sleeper, you will be most comfortable with the soft side of the mattress. However, back sleepers will find firm side more suitable as it gives ample support to hold your body in an aligned position.
Heavier set individuals might find this mattress not firm enough to support their weight. If you are anywhere above 220 lbs., you should have a look at Nolah Evolution 15 Mattress.
Side sleepers should ideally opt for something more softer than a medium-soft. However, it totally depends on personal choice to prefer support along with cushion.
Construction
The mattress can be a 7″ or 9″ thick and consists of 6 layers:
- Mattress cover
- Wool fire barrier
- Medium latex support layer
- Firm latex support layer
- Second wool fire barrier
- Second mattress cover
The mattress cover on both sides is made up of a very fine quality certified organic cotton, stretched (not woven).
Right under both sides of the covers sits a wool fire barrier that helps exceed safety standards free from any toxic chemicals. This layer helps the mattress regulate temperature and you sleep cool. People who tend to sleep hot will find this mattress cooling.
The soft side of the Latex for Less mattress has a 100% natural talalay latex layer that is a bit softer compared to the one under it on the firm side. This layer helps the mattress provide soft or firm sleeping surface to the user.
The material used to manufacture Latex for Less mattresses are all certified by GOTS, Oeko-Tex standard 100 and Eco-Institut for purity. The mattress is organic and most suited to people who support eco-friendly products.
Sizes
