We Reviewed the 5 Best Mattresses for Side Sleepers

Getting a new mattress is not a straightforward task. With the number of options available in the market, the decision can be a daunting one. But even if the thought of all the different options, price points, and features drains you out, you can’t rest easy until you make this decision, because, well you don’t have a mattress to rest on.

Lucky for you, this mattress buying guide will walk you through the process of choosing the right mattress so that you can narrow down your choices one decision at a time.

Mattress Shopping- In-Store or Online?

So, first things first. Are you going to shop for your new mattress in-store or online? In-store shopping is the more traditional route to go when mattress shopping because you have the luxury of stretching out on the mattress and testing it out before committing to one. However, thanks to flexible return and exchange policies, online mattress shopping has also become quite popular lately.

Most online retailers offer 30 to 60-day return or exchange policies, that allow you to try out your mattress for up to 2 months, instead of a quick lie-down for a few minutes in the store. Moreover, with online shopping, you are less likely to make a rushed decision and can carefully compare prices from different vendors to make sure you get the best deal.

Mattress Buying Guide

Choose the Mattress Type

You can find several types of mattresses in the market- foam, innerspring, hybrid, latex, and adjustable air mattresses. Deciding which type of mattress is suitable for you depends upon a number of factors such as whether the position you sleep in, your bed partner’s sleeping position and habits, your preferred level of firmness, and whether you sleep hot or cold, etc.

Innerspring mattresses provide support through a series of steel coils that are encased within thin layers of comfort foam or fiber.  The coils in an innerspring mattress are the reason behind their characteristic bouncy or springy feeling. The intensity of the bounce depends upon the density of coils as well as whether the coils are interconnected or pocketed. The coils of innerspring mattresses are usually reinforced for better support near the edges of the mattress. This minimizes sags or the risk of the mattress occupant rolling off the edge.

On the other hand, foam mattresses are less springy, and firmer. Foam mattresses have a foam base and additional comfort layers that can be comprised of memory foam layers, open-cell foam, gel-infused foam layer, or viscoelastic memory foam layers, etc. Different types of layers have different benefits and combining multiple layers in a foam mattress helps take advantage of the benefits of all. The base of foam mattresses comprises durable and supportive materials such as polyfoam. The main advantage of foam mattresses is that they cushion and contour the body’s pressure points such as the hips and shoulders. They also help ensure proper spine alignment, which in turn leads to fewer backaches. Newer models in the memory foam lines include mattresses with multiple layers of foams. The bottom layers are heavier and harder, for extra support, while the upper layers and softer and cooler for extra comfort.

Latex mattresses are made using comfort layers and a support base made out of latex. The two types of latex that are commonly used are Dunlop latex or Talalay latex. Synthetic latex, although less common, is also used sometimes. Like foam, latex too contours the body and provides pressure relief. Its advantage though is that latex mattresses usually allow for more airflow, thereby helping with regulating temperature. This is especially useful for people who tend to sleep hot.

Hybrid mattresses offer a great balance between innerspring and foam mattresses. The core comprises an innerspring support system, which is surrounded by layers of foam or latex. The combination helps minimizes the shortcomings of each mattress type and maximizes the advantages of each.

The final type of mattresses is airbed mattresses. Air mattresses are little more than slabs of rubber or PVC that are filled with air. The firmness of the mattress depends upon the amount of air inside or in other words, the air pressure in the mattress. More sophisticated airbeds come with electric in-built pumps that allow you to adjust the firmness with the touch of a button. Moreover, dual-chamber air mattresses are the ultimate solution for bed partners with different mattress firmness preferences. This is because both chambers of the air bed can be controlled separately.

Mattress Types for Different Sleeping Positions

According to our surveys, side sleepers generally prefer a softer mattress, while back and stomach sleepers prefer a firmer mattress.

If you are a side sleeper, you want a mattress that provides support without causing pain in your shoulders or side. Innerspring or soft foam mattresses are a good option to consider for side sleepers as they can support the bodyweight easily while also conforming to the body so that you wake up without a sore shoulder, hips, or side.

On the other hand, stomach sleepers generally prefer a firmer sleeping surface that doesn’t make them feel as if they are sinking into the mattress. This is why, a firm memory foam or even a spring mattress with dense springs, can be good options for stomach sleepers.

And lastly, those who sleep on their backs, want the ideal balance of support and comfort. A firm mattress that keeps the spine aligned, while also providing pressure relief to your body. Adjustable mattresses such as air mattresses, or innerspring mattresses are a more suitable option for back sleepers.

What to Look for in a Mattress for Side Sleepers

If you are a side sleeper and are in the hunt for a new mattress, there are two key things to look out for in order to get the most comfortable sleep:

·   Back support and spine alignment

·   Pressure relief for less shoulder pain

Sleeping on the side is often touted as the ideal position to sleep in for avoiding backaches and for maintaining spinal health. This is because when you are sleeping on the side, your spine is in a neutral position, and there is no pressure on the spine. However, this is only true if your mattress is of the right firmness level and provides sufficient support. For this, memory foam mattresses are the answer. This is because they contour to the body better and provide support to all the key joints and body parts. Look for a mattress that provides a smooth surface and is free of any sags or dents.

The level of firmness of your mattress is also important to ensure pain-free nights and days for side sleepers. Soft mattresses don’t provide enough support and firm mattresses can often put too much pressure on the shoulders leading to painful shoulders in the morning. This is why side sleepers should ideally look for a mattress that is medium to firm with a pressure relief design.

Mattress Shopping Tips

1. Lie Down on the Mattress

If you are shopping in-store for a new mattress, the most important thing to do is to try out the mattress by lying down on it. Instead of just a quick lie-down, take your time making yourself comfortable on the bed, and see if the mattress works for you. Plan to spend at least 10 to 15 minutes on the mattress before committing to any.

If you are buying a mattress online and don’t have the luxury of lying down on the mattress before making the purchase, make sure that you purchase one with a decent trial period or tone that has a flexible return or exchange policy. This way, you will be able to try out the mattress for a few days to see if it is the right fit for you.

2. Look for Return or Trial Policies

Whether you are buying in-store or online, it is important to make sure that your mattress comes with a flexible return and/or exchange policy. Deciding whether a mattress is a suitable fit or not based on a 10 to 15 min lie down is next to impossible. This is why it is better to opt for a mattress from a vendor that offers favorable return and exchange policies. Most mattress manufacturers offer anywhere between a couple of weeks to several months of trial periods. Free pickup, extensive return periods, or customer support are some extra benefits to look out for.

3. Get the Best Price

When buying a mattress from a store, there is a good chance that with some negotiation, you might be able to bring down the price a bit, or at least ask for complimentary add-on services such as old mattress removal or delivery service if these aren’t already included in the price. When buying online, the prices are usually fixed, but even then, a quick Google search might give you a promo code that can help knock a few dollars off the asking price.

4. Box Spring or Not?

Most mattress retailers would try to upsell their products by insisting that you need a box spring too. However, it might not be needed. Check to see if your current box spring is structurally in good condition and is the same size as the new mattress you are thinking of buying. Depending upon the brand and size of the mattress you are thinking of purchasing, you will be able to save a few hundred dollars by sticking with your old box spring. It is important to remember though that, some mattress brands will only provide complete warranty coverage to your mattress if you purchase the accompanying box spring too.

5. Know the Warranty Policy

Typically warranty periods for mattresses range from 10 to 25 years. However, most warranties only cover manufacturing defects and even this coverage can decrease over the years.  It is important to note, however, that a longer warranty period doesn’t automatically mean a more durable or higher quality mattress. It is important to take other factors such as the material used, the number of layers, base, and firmness into consideration.

6. Inspect Your Mattress Upon Delivery

When your mattress is delivered, inspect it thoroughly to ensure it doesn’t have any defects, stains, or signs of damage. If it looks damaged or doesn’t look new, don’t accept the delivery. In case, the mattress is in a box, unroll and inspect it as soon as you receive it. Contact customer support if there is an issue with the mattress. Taking pictures of any defects or stains can also be helpful in case you are asked to provide those for warranty claim purposes.

7. Account for Stretching or Adjusting Periods

Most mattresses, especially if they are mattresses-in-a-box, will take some time to gain their proper shape, form, and level of firmness when they are unrolled for the first time. Allow up to 72 hours for the mattress to stretch before sleeping on it. Moreover, if you changed a mattress, there might be a bit of an adjustment phase during which your body gets used to the new mattress. This is why most mattress manufacturers give trial periods of at least a few days so that you can judge the mattress objectively once your body has adjusted to it.
