Best 6 Inch Mattress Options Online in 2021

Where to buy a 6 inch mattress online


In this post we have listed the best 6 inch mattress options available to purchase online. 6 inch mattresses are generally the thinnest mattresses that manufactures will make, due to the need for sufficient layers of support. While 6 inch mattresses do come in all sizes they are most commonly used on twins and fulls or for bunk bed mattresses. Many 6 inch mattresses are poorly made and will not hold up to heavy use. We have done all the research and have listed our favorite options online.

Is a 6 inch mattress enough support?

A 6 inch mattress is going to be built with a bottom layer of support foam and a top layer of memory foam or comfort foam. This built is enough support for the majority of sleepers, however, it may feel very firm for heavier individuals. We generally recommend that adults opt for at least an 8 inch mattress if it is something they will sleep on every night, while kids can happily sleep on a 6 inch mattress. 

What is a 6 inch mattress used for?

Bunk Bed Mattress: 6 inch mattresses are often used as mattresses for bunk beds. This is due to the fact that the thinner profile can allow the sleeper to be lower and not rise above the safety rails. 6″ mattresses are the most common option chosen for bunk beds, especially for the top bunk. 

Daybed Mattress: Daybeds often utilize a thinner mattress in order to allow for more room for sitting and lounging. Daybeds also generally need to be firmer to support sitting and sleeping positions, so a thinner mattress is often a firmer sleeping surface than a thicker mattress. 

Trundle Mattress: Trundle mattresses generally need to be thinner in order to slide underneath the bed set they are attached to. Often a 6″ or 8″ mattress is required. 

Kids Mattress:  Mattresses for kids are generally thinner than adult mattresses because they are more affordable and do not need to support as much weight. A 6″ mattress will cost almost half the price of a 12″ mattress and will still provide the comfort that a young child needs. 

Things to consider before buying a 6 inch mattress.

Frequency of Usage: We have listed mattresses that meet all standards and budgets. Be sure to think about how often you will be using your mattress. If it will be a guest bed or an extra sleeper you may want to go with a budget mattress, while if it is an every night sleeper you may lean towards a more luxury sleeping experience. 

Material: When it comes to material memory foam, latex and innerspring mattresses all have different benefits and feels. It is important to know which you prefer and choose a mattress that meets your needs. 

Price: Generally speaking, the more expensive the mattress the higher quality materials and the longer it will last. Our best all around mattress is a great middle ground between quality materials and an affordable price. 

The different types of three 6 inch mattresses available

6 inch mattresses are very common in the marketplace due to their affordability and thin profile. There are a variety of options and different materials to choose from, each with its own benefits and downsides. 

Memory Foam 3/4 mattress: Memory foam was originally invented and used by NASA and ultimately transitioned into use within the sleep industry. Memory foam has great pressure relief abilities but can have a unique feel that takes some getting used to. If you have never slept on a memory foam mattress we recommend testing one out before deciding to purchase one. 

Latex 3/4 mattress: Latex is one of the most natural and eco-friendly materials in the bedding industry. Latex is not only a popular health-conscious choice but it also has amazing pressure relief and support capabilities. The only downside to latex is that it is quite a bit more expensive than competing foams.
