Best Soft Mattress Topper For Side Sleepers

Read our review of the best soft mattress topper for side sleepers.

If you are in a hurry and just want to know what the best soft mattress topper for side sleepers is, I recommend the Plushbeds Vegan Down Alternative Mattress Topper.

Side sleepers deal with pressure at the shoulders and the hips which can lead to sleep-related pains and aches. To prevent this, you can tailor your sleeping surface to cushion and support your body, especially at the pressure points. 

While the best solution would be to invest in a suitable mattress, you can also transform your current mattress by using a new mattress topper on it. High-quality mattress toppers are made of materials such as gel memory foam, traditional memory foam, natural latex, down, and down alternative.

Mattress toppers for side sleepers can have varied densities ranging from soft to firm. Soft toppers are suitable for use with a new or firm mattress.

We have reviewed several soft mattress toppers to come up with the best topper for side sleepers.

Today I am reviewing the following soft mattress toppers for side sleepers:

Things to consider when buying a soft mattress topper for side sleepers

Why should a side sleeper use a mattress topper?

A side sleeper may suffer pressure at the shoulders and hips if they use a firm mattress which can lead to aches and discomforts. On the other hand, the hip and shoulder can sink and misalign the spine if the mattress is too soft. Most mattress toppers for side sleepers can help offer either the support or cradling needed to avoid such issues.

Is a soft mattress good for side sleepers?

A soft mattress may relieve pressure at the hip and shoulders but it may also cause sinking that can misalign the spine and cause pain or discomfort. With a medium-soft to a medium-firm mattress, people who sleep on the side can get both the cradling and the support they need.

Is a pillow-top mattress good for side sleepers?

Most pillowtop mattresses come with firm support cores and a soft contouring pillowy top. This combination offers a good balance of cushioning and support that a side sleeper needs.

Are latex mattress toppers safe?

All-natural latex mattress toppers are safe. However, synthetic latex is known to release VOCs (Volatile organic compounds) that can be toxic with prolonged exposure. Notably, the same VOCs are released by so many other household products  and materials such as detergents, aerosol sprays, and furnishings so, in addition to synthetic latex, you might want to check those as well.

How can latex be organic?

Latex is organic if it is made from the sap of rubber trees farmed without the use of herbicides, pesticides, and other man-made chemicals and processed without fillers and synthetic compounds.

Is a latex mattress topper good for side sleepers?

Latex toppers are body contouring yet supportive, making them great for side sleepers. A latex topper will help keep the spine aligned and provide pressure relief at the shoulders and hips.

What is the best mattress topper for side sleepers with hip pain?

Hip pain can occur or be made worse by pressure at the hip from a hard mattress. A relatively soft or plush mattress topper made from latex foam, memory foam, wool, or cotton can help with the pain.
