Firmness, Comfort & Support

Both mattresses have a medium firmness rating so are easily comparable. Many bed in a box companies go for a medium firmness as it suits the widest number of sleepers. Let’s look at the pros and cons of the Emma vs Simba in this department.

Simba Hybrid Mattress
Dropdown arrow
  • Due to its layer of latex, the Simba Hybrid mattress is both responsive and comfortable, and is highly breathable.
  • The layer of microcoils help to create a good level of sinkage without any pressure points being created.
  • The microcoils also help to add a little more bounce than you would normally get from a foam mattress.
  • The contour and hug of the Simba Hybrid mattress provides a great mix of sinkage, contour and support.
  • Lighter weight sleepers may find that the Simba Hybrid mattress is a little too firm for them, as the mattress will not ‘sink’ as much to contour round them.
  • Simba’s mattresses are ideal for couples of differing weight, as there is no discernable ‘roll’ towards each other whilst sleeping. However, the mattress can dip on one side over time.
Emma Original Mattress
Dropdown arrow
  • Both Emma mattresses have a higher level of bounce than most bed in a box brands.
  • The Emma Original does have some motion transfer but the build of the mattress absorbs energy well and helps to dissipate the motion. Light sleepers may notice movement.
  • A balanced level of sinkage in both mattresses means that you never feel stuck in the mattress.
  • Extremely breathable foams and cover helps to keep sleepers cool.
  • Both mattresses are softer than other bed in a box brands, but are particularly good for front sleepers.

Simba vs Emma other factors

What else should you consider when you're comparing the Emma vs Simba mattresses? Both Simba and Emma offer a trial period of 200 nights, with a full refund if you’re not satisfied and come with a 10-year guarantee. You can also apply for up to 12 months interest free credit to pay for the mattress, and there’s free one-day delivery to most of the UK.

Do bear in mind that as these mattresses come delivered in sealed boxes they will have a rubbery smell when first extracted. They need a good few hours in a room with the windows open before you sleep on them.

The verdict - Emma or Simba mattress?

Both mattresses offer appealing factors, but here are some points to consider when deciding which best meets your requirements.

We'd recommend the Simba Hybrid Mattress if:

  • You want a hybrid mattress. The Simba uses latex, microcoils, memory foam and a 7-zoned support foam. All this makes for a responsive mattress with good support.
  • You sleep on your side or back and want a mattress that responds to pressure in a faster manner than most foam mattresses.
  • You want good edge support. Because of the extra layer of foam around the perimeter of the coils, the Simba maintains its support around the edges.
  • You’re of a light to medium build, as some users of a heavier build report that the mattress can be prone to sinkage on one side over time.

We'd recommend the Emma Original Mattress if:

  • You want a mattress that responds quickly to pressure points, due to its combination of foams and zoned support.
  • You are not a particularly light sleeper, as the motion transfer in Emma mattresses can wake lighter sleepers.
  • You sleep in any position, although the Emma is particularly supportive for side sleepers.
  • You like the slightly softer feel of an all foam mattress
