OPTRABEANS™  Bean Bag Refill

Bean bags are known to be a popular accessory to any home or office. They are extremely comfortable to rest on and are very effective in enhancing the appearance and ambience of any given space. Extremely versatile, they serve as a comfortable decor piece for you to work or rest on. They can also be conveniently carried to any corner of your home or office.

However, bean bag owners will always face two problems, and that is to know what type of bean bag refill to buy, and how much bean bag refill to buy. Find our how much bean bag refill to buy with our comprehensive guide here.

Regarding the types of bean bag refill that you can buy, there has always been an ongoing debate among Expanded Polypropylene (EPP), Expanded Polystyrene (EPS), and OPTRABeans (EEPS). Without further ado, let’s take a closer look at each of these options.

For those who would like a much summarised version, you may refer to these two graphs below:

Density over time

The comparison on how long each type of bean bag refill would last can be seen here. OPTRABEANS Enhanced EPS can last up to 10 years without losing its density or shape, while still providing maximum comfort.

Comparison and Summary

The comparison of all 3 types of bean bag refills can be seen in this graph. 

Expanded Polypropylene (EPP)

EPP is a plastic based material that is shaped into any possible shape through heat. At room temperature, it is extremely strong and durable. Pressure from average human mass of 40 to 80 kg will not be able to flatten it.


  • Strong: EPP beads will never lose its volume, even through the course of 10 decades.


  • Uncomfortable: EPP beads are really hard. Lying on a bean bag filled with EPP beans will not allow you to roll around as easily as you would like.
  • Heavier: EPP is much more dense and heavy. Carrying your bean bag around may now seem like a chore.
  • Fire Hazard: EPP is a plastic that tends to catch fire a lot more easily as compared to others.

Expanded Polystyrene (EPS)

Another type of plastic that is made into tiny beads that can be used to make plenty of products such as Styrofoam boxes and other types of Styrofoam protective materials. This is the most commonly used bean bag filling in the world.


  • Resistant to heat and moisture, a great conductor to heat
  • Very lightweight. 95% air.
  • Comfortable, lasts up to 1 year.


  • Non-biodegradable
  • Poorer quality EPS may have a very ‘plastic-like’ odour. 


OPTRABEANS, an evolved version of EPS is more often referred to as Enhanced EPS. It is manufactured by expanded raw beads into beans that are 3 to 5 mm in diameter. Its composition is 98% air, and most importantly, it is odourless. Its longevity is also enhanced to about 7 to 10 years.


  • Resistant to heat and moisture, a great conductor to heat
  • Very lightweight. 98% air.
  • Comfortable, lasts up to 10 years
  • Odourless
  • Recyclable
