Sleepwell mattress price

On average, the price of a Sleepwell mattress ranges between ₹8,000 and ₹84,000. 💰

If the mattress lasts seven years, it will only cost you ₹13 a day, which is more than fair.

Sleepwell has a massive selection of mattresses available, with their innovative materials, including impressions foam, resitec foam, pocket spring, high-density PU foam mattress, and many more.
Sleepwell is famous for its comfortable and breathable mattress. 🤗
But how do you navigate this space and find a suitable mattress for your preferences?
Luckily, Sleep Hero is here to help you.
The Sleepwell mattress can be divided by its material or collection.
Each collection category includes a variety of mattresses made from different innovative materials introduced by Sleepwell.
So, let's look at the materials first offered by this leading mattress brand. 👀
Sleepwell mattress materials
Sleepwell offers mattresses in a dozen different materials to improve their customers' experience.
They try to strike the perfect balance between their customer's needs and the latest advancements.
Sleepwell has introduced its innovative foams used in most of its mattresses. 🧽
The most popular innovative materials used by the brand are:
- Sleepwell Quiltec foam
- Sleepwell Impressions foam
- Sleepwell Resitec foam
- Sleepwell Air-O-Fresh foam
Let's look at these materials in a little more detail. 👇
Sleepwell Quiltec foam
The Quiltec foam offered by Sleepwell is an ingenious foam that offers a plush surface feel to the mattress.
The foam enhances the airflow and dissipates heat uniformly across the mattress. 💨
This, in turn, helps eliminate any humidity, making it perfect for hot sleepers.
The Quiltec foam has a superior loft when compared to other quilting foams.
The addition of this foam makes the mattress suitable for the elderly. 👴
Sleepwell Impressions foam
The Impressions foam introduced by Sleepwell naturally adjusts to the contours of your body.
The mattress's soft, snug contour hugging experience ensures that all the pressure is distributed evenly while you’re sleeping. 😴
This shape adjustment offered by the foam also enhances blood circulation.
This innovative breakthrough material is independent of the surrounding temperature. 🌡️
It means that the Impressions foam offers the same comfort level in all seasons.
Since the impression foam is made of quilting material, it offers a plush surface feel to the mattress.
Sleepwell Resitec foam
The Sleepwell Resitec foam is made of high-quality materials that offer a cushioning feel to the mattress.
The plush, bouncy surface feel gives you a comfortable night of sleep. 🛌🏽
This foam offers optimal body support and enhanced pressure point relief.
Sleepwell’s resitec foam is best for orthopaedic mattresses and sleepers suffering from back or pressure point pain. 😩
Sleepwell Air-O-Fresh foam
The Sleepwell Air-O-Fresh foam has a unique cell structure that ensures uniform firmness across the mattress.

It offers optimal body support and distributes pressure evenly while sleeping. 🤗
The open cell structure also promotes air circulation, enhances airflow, and dissipates heat quickly.
This makes the Air-O-Fresh foam material perfect for humid climates. 🥵
Sleepwell mattress by collection
Most Sleepwell mattresses will include one of the materials mentioned above.
These mattresses would then be divided into one of the three collections this leading brand offers.
These collections include:
- Need
- User
- Comfort
- Price
The mattresses are categorised in these collections to enhance their customers' shopping experience.
The brand allows you to sort out their mattresses based on your need, user, and comfort when scrolling through their website. 🔎
The mattresses are then categorised to make finding the one that fits your needs easier.
Features of a good Sleepwell mattress
Sleepwell has a wide range of mattress features to make you feel good when it's time for sleep. 😴
Reversible
The best Sleepwell mattress offers a reversible feature so that you can use it both ways.
One of the sides is usually softer than the other to maximise comfort.
Moreover, it’s perfect for people with specific needs where you want more support on occasion.
In addition, when your partner's sleep habits change, you can consider the reversible mattresses that offer two surfaces of varying degrees of cushiness. 🧑🤝🧑
Double-stitched edges
Not only are the edges of these mattresses stitched twice, but they're also a much more durable fabric than other mattresses.
This is a smart purchase if you tend to tear up your sheets or mattress covers easily. 🛒
Pillowtop
Sleepwell mattresses come with pillow tops that provide an extra layer to provide additional cushion.
Pillowtop mattresses can make your sleep more comfortable and enjoyable because you will experience more minor pressure points in critical areas while sleeping. 🛌

Not all pillow tops offer this same level of comfort or durability - so be sure to do your research before making any purchases.
Hypoallergenic
The surface of the mattress, is made such that it doesn't produce dust-related allergies.
It's an excellent feature for allergy sufferers and asthma patients alike. 🤧
How comfortable is a Sleepwell mattress?
When it comes to comfort, it is pretty challenging to give a standard answer on all the mattresses offered by this brand. 😬
Sleepwell gives you access to more than 30 mattresses made up of a different combination of foams and materials.
With that said, most of the reviews left behind by Sleepwell customers are favourable.
The company has been serving the Indian audience for the past 28 years. 📅
They have innovated their registered materials that work well with their customer's needs and the latest sleeping technology.
However, a few customers feel that the more affordable mattress options are too firm for their liking. 😟

Even though the company has added rebonded foam and meshes to improve the mattress's durability, most offer just five years of warranty.
This means that you shouldn't expect a longer lifespan for a Sleepwell mattress.
If you are looking for a more durable mattress, you can choose a SleepyCat or Durfi mattress.
Who are Sleepwell mattresses suitable for?
The Sleepwell mattress is targeted more toward high-income families. 💵
While they have more affordable mattress options available, they are still pricey compared to other mattress brands.
If you’re looking for a good quality mattress with proper air circulation, a Sleepwell mattress is suitable.
A Sleepwell mattress can be recommended for a couple, the elderly, and someone looking for optimal back support.
A good choice for couples
Sleepwell offers a range of mattress options that absorb movement and are an excellent choice for couples. 👫

They offer good pressure distribution across the mattress and have low motion isolation.
The mattress options that are available for couples also offer exceptional edge support.
With the foam wall technology, these mattresses offer the same support at the very edge of the mattress and prevent any side sagging. 🙅♀️
A good choice for the elderly
The exceptional edge support offered by the high-end Sleepwell mattress is also particularly good for the elderly. 👵

Most old-aged individuals need to sit on the edge of the bed for a minute or two before getting up.
The side anti-sag feature would keep their mattress durable for a longer time. 📅
A Sleepwell mattress also has a higher loft than other mattress brands.
This is also a particularly favourable feature for the elderly as it makes it easier for them to get in and out of their bed.
A good choice for people looking for optimal back support
Sleepwell's mattresses are designed while keeping optimal back support in mind.

The impressions and rebonded foam mattresses offered by the brand offer contour hugging features.
These mattresses distribute your weight and pressure evenly, giving you a night of cosy and comfortable sleep. 😴
Who are Sleepwell mattresses not suitable for?
While Sleepwell mattresses offer a wide range of collections that might be suitable for different needs, they are typically aimed at a high-income family group. 💵

If you are looking for a more affordable mattress, Sleepwell might not be the best option.
Instead, you can look for SleepyCat mattresses that offer more affordable options.
No trial period
All the mattresses offered by Sleepwell do not have a trial period. 🙅
So, if you are ordering their mattresses online and are unsure what fits your sleeping needs, you might have a little trouble.
Without a trial period, you cannot break in your new mattress and decide whether it’s the right fit for you.
If you are looking for a mattress brand that will let you try your mattress without any risks, then Sleepwell is not the perfect fit for you.
Short guarantee period
Most of the mattresses offered by Sleepwell come with a 3 or 5-year guarantee.
While this does not mean that your mattress won't last you longer than five years, the company won't guarantee that.
There are a few customer reviews who did not have an enjoyable experience regarding the mattress's durability. 😔
If you are looking for a mattress that will last you more than 10 years, then Sleepwell is not the best option.
Instead, try out other brands like SleepyCat, Durfi, or Kurlon mattresses.

How do you find the best Sleepwell mattress?
The right mattress could be the difference between a restless or peaceful night and your best sleeping experience.
So how do you know which is the best mattress in Sleepwell? 🤔
Here are a few factors to keep in mind while buying the right mattress [1].
Weight distribution
It's vital to check the weight distribution and your body structure.
This will help you determine where pressure points might develop.
Support requirements
It's essential to choose a mattress that will provide the right amount of support for you.
When it comes to soft mattresses, they usually provide adequate back and pelvis alignment initially. 🛌
However, their softer features make them less supportive after some time of usage than other types of beds.
The Sleepwell spring mattress is known for its consistently supportive nature throughout its lifespan.
Sleeping position
Mattress comfort changes based on the sleeping position.

Here are some simple suggestions for choosing a mattress based on your sleeping position. 👇
Side or back sleepers
Side and back sleepers need a softer sleeping surface so that their shoulders and hips can avoid painful pressure points.
Stomach sleepers
Stomach sleepers will often want a firmer sleeping surface so that they can keep their spine in line and prevent back pain.
Mattress thickness
The thickness of the mattress is important for your comfort.
Most Sleepwell mattresses are at least 7 inches thick.
Your body weight determines if a thinner or thicker bed will be more comfortable for you. 🛏️
For a heavy individual, thicker beds are more comfortable. However, in the case of lightweight individuals, thinner ones are preferred.
Firmness
The firmness of the mattress depends on two principal factors - the weight of the person sleeping and their sleep position.
If you weigh less than 60 kg, go for a softer bed.
If your weight is more than 60kgs, look for a mattress that offers more support.
The conforming ability will be based on how soft or hard your new mattress is.
Durability
The average durability of a Sleepwell mattress in India is about seven years.
A Sleepwell memory foam mattress usually has a lifespan between 10-15 years, but Sleepwell latex plus mattresses are even more durable.
Memory foam mattresses typically last anywhere from 10-15 years, where spring types range just under five.📅
Sleepwell mattress sizes
The size of mattresses is a significant factor that you should take into consideration.

If the mattress you are going to buy isn't the right size, you will never be able to feel comfortable. 🥱
The best part about Sleepwell mattresses is that they are available in all sizes including, single, double, queen, king, and custom sizes.
Therefore, choose your mattress wisely by taking dimensions and preference needs into account when making a purchase decision.
Sleepwell mattress delivery conditions
Sleepwell delivers its mattresses free of charge to most of the pin codes within the country.
However, for a few pin-codes, there might be a minimum amount you should have spent to avail of the free delivery option.
The mattress offered by Sleepwell comes with a standard two-person delivery service. 👬

Your chosen Sleepwell mattress is delivered to your home.
You can also choose the installation option, where the delivery men will install the mattress in the room of your choice. 🏠
Some Sleepwell mattresses and accessories are also available at online stores, including Amazon.
Your mattress will be delivered to your door when you order through Amazon.
It will be delivered in safe and secure packaging to ensure long shelf life.
Sleepwell mattress trial periods
One of the most significant disadvantages of buying a Sleepwell mattress is their no risk-free trial periods. 😔
Whether you buy from their store, online partner, or their website, the company does not give you access to a trial period.
You need a few days to break in your new mattress.
Only then you can decide whether the mattress suits your comfort or not. 🛏️
Without a trial period, it becomes difficult for you to analyse whether the mattress is the best fit for your needs.
Other mattress brands, like Wakefit or Tempur mattresses, offer a 100-night risk-free trial.
