Best Thick Mattress Topper 2022


Written by Daniella

Last Updated: 29th January, 2022

A mattress topper is an additional layer (they average about 5cm or 6cm) of bedding placed on your mattress to provide extra comfort, support, to add warmth or coolness, prolong the lifespan, or rejuvenate an old tired mattress.

A thick mattress topper is usually between about 6cm and 10cm and may provide that extra comfort you are looking for, especially if you are currently sleeping on a firm mattress with many springs. It may be especially beneficial for those whose current mattress is too firm and not providing sufficient pressure point relief or correct spinal alignment. Or if the mattress is not well-suited to your sleeping position.

When purchasing a thick topper, there are different things to consider, such as price, materials, quality, and of course, the thickness best suited to your needs.

Thick Mattress Toppers: Considerations

There are a variety of thick mattress toppers on the market, and one could get overwhelmed with the overload of information and appealing advertising. It is, however, always advisable to choose bedding that is best suited to individual needs and preferences. As a basic rule, the thicker the topper, the more potential softness and cushioning it can provide. However, it is important to note that the thickest plushest topper may not be best suited to your needs. The following points are worth considering when choosing the best thick mattress topper for you.

Thick mattress toppers considerations
  • Firmness: Generally, the thicker the topper, the softer the feel.
  • Sleeping position: A thicker, soft mattress topper may be a good option for side or back sleepers. The added cushioning provides pressure point relief for the shoulders and hips and optimal spinal alignment. Stomach sleepers should instead consider a thinner, firm mattress topper as the hips tend to sink too much into a soft surface, causing incorrect spinal alignment.
  • Couples: If you sleep next to a partner with different sleep surface requirements or preferences, it may be a good idea to invest in a single topper specific to either yours or their needs.
  • Materials: Certain features such as temperature regulation and hypoallergenic characteristics are dependent on the materials used. If you are a hot sleeper, have allergies or sensitive skin, you should choose accordingly.
  • Eco-friendly: The materials and chemicals used as well as construction methods will determine how planet-friendly the topper is. Additionally, check for certification labels like CertiPur® on foam toppers if you are concerned about the use of harmful chemicals in the materials or manufacturing process.

Good to know!
Responsible Down Standard (RDS) is a certification that products that contain feathers and down come from certified farms compliant with the principles and criteria of animal welfare.

  • Trial period: This could be important as it gives you peace of mind when buying the topper that it can be returned/swopped if you are not happy with it.
  • Care: Many thick mattress toppers aren’t washable. Some have removable covers. If this matters to you, make sure you purchase a machine-washable topper/topper with a removable, washable cover.
  • Your weight: As the thicker toppers tend to be the softest, be sure to keep your weight in mind. Heavy people often sink further down, which may eventually cause the topper to sag or cause discomfort to the sleeper.
  • Durability: The type and quality of materials used and construction method will often determine how long your mattress topper will last.
  • Price: As with most bedding, the price is often a reflection of the quality of materials used. As a rough guide, the more expensive toppers may have a longer lifespan than the cheaper mattress toppers.

Thick Mattress Topper Materials

Adding a topper to your existing mattress may significantly change the feel, so it’s good to know what to expect. Different materials offer different benefits, and it is useful to know the advantages and disadvantages of each so that you are able to make the most well-informed decision.

Memory Foam

Memory foam is body-contouring, low rebound, flexible, cushioning and comfortable. It can provide a good balance of pressure relief and support, as well as promote motion isolation. However, it’s worth noting that memory foam mattress toppers may not be ideal for hot sleepers as they tend to retain heat (some have special features for cooling such as gel and graphite infusions), and for some, changing position can be a bit difficult.


​​Natural latex mattress toppers could be a good option for those keen to use more natural products as the material is derived from the sap from rubber trees. Latex is high rebound, comfortable, self-ventilating, durable, pressure-relieving, and breathable; however, it tends to be on the pricier side and too firm for some.


Wool is known for having a very soft and cushioning feel, as well as being durable, thermoregulatory, hypoallergenic, antibacterial, supportive and pressure relieving. In addition, wool mattress toppers are often renewable and biodegradable, and are therefore ideal for those who are more environmentally conscious. 

Hollow Fibre

This material is commonly used in thick mattress toppers and is made using fine, hollow strands of polyester. These hollow fibres trap air inside them, and this material is therefore known to be lofty, lightweight, soft and breathable. Additionally, hollow fibre tends to be cheaper than other materials, such as foam or latex. 

Thick Mattress Toppers For Back Pain

As mentioned, the thickness and firmness of mattress toppers go hand in hand, and much literature is dedicated to the study of which sleep surface is optimal for those with back pain. As a result, manufacturers in the bedding industry have designed specific models to cater for this, naming them specifically “orthopaedic mattresses”, “orthopaedic mattress toppers”, or “mattress toppers for back pain”.

Thick mattress toppers for back pain

Whether sleeping on a firmer or softer surface is better for back pain is one of the most common questions patients ask doctors, as well as one of the most-asked questions regarding back pain online. In the past, doctors recommended a firmer surface, and many mattresses and mattress toppers advertised as best-suited for those with bad backs are on the firmer side. However, some research✓ shows that the use of medium-firm mattresses for adults with and without back pain improved sleep quality, pain reduction, and spinal alignment. Literature✓ , however, remains, for the most part, inconsistent on this. 

Ultimately there is no “one size fits all” solution. In general, the best thick mattress topper choice will be firm enough, offering the necessary support where needed, and soft enough so that there is cushioning and pressure relief in critical areas, but not so soft that you sink in and battle to move.

Who Should Use A Thick Mattress Topper

Some people may gain more benefits than others from using a thick mattress topper. If you fit some or all of the categories below, a thick mattress topper may be a great potential option for you. If not, choosing a brand that offers a trial period to try it out might be a good option.

Who should use a thick mattress topper
  • Comfort Seekers: If plush padding is your thing, a thick topper is a good choice because it can provide that extra cushioned feeling.
  • Lighter individuals: Those on the lighter side may find that a thick, soft topper provides the perfect balance between comfort and support - plenty of cushioning compared to a firm surface and no uncomfortable sinkage.
  • Pain sufferers: A thick topper can provide comfort and extra cushioning for those with injuries or musculoskeletal pain.
  • Side and back sleepers: People who sleep in these positions tend to need more pressure point relief in their shoulders and hips. A thick topper may provide sufficient cushioning in these areas as well as keep the spine correctly aligned.

Who Should Avoid A Thick Mattress Topper

Some people are more likely to find thick mattress toppers uncomfortable, or that they cause pain. If you fit some or all of the categories below, it may be wise to consider alternatives to a thick mattress topper.

Who should avoid a thick mattress topper
  • Support seekers: Sleepers who prefer a more supportive sleep surface may not enjoy the sinking cushioning feel of a thick mattress topper - a firm mattress topper may be a better choice.
  • Heavy individuals: Thick toppers may not be ideal for heavy people as they tend to experience too much sinking. The use of soft materials may also result in the topper sagging over time and a shortened lifespan.
  • Infants: Thick, soft toppers should be avoided in infants and young children. Soft bedding has, in fact, been shown✓ to be a risk factor for sudden infant death syndrome✓ (SIDs) due to the possibility of covered airways.
  • Stomach sleepers: Stomach sleepers tend to be better suited to thinner or a firm/medium-firm topper so that the hip area is sufficiently supported and sleepers don't end up with a sore back.
