Mattress buying has been turned upside down since the arrival of “bed in a box” online mattress retailers. Not only have these brands given us greater choice, we also have the invaluable opportunity of a decent trial period to ensure that a perfect night’s sleep has been achieved. If you want to get in on the action, Finder can help!

Overview of Casper

Casper launched its fast-growing, global company in 2014 with a mattress which has won multiple awards for innovation and design. Casper boasts a widely acclaimed sleep surface, sleek design and ease of delivery.

Casper’s newer hybrid mattress is made from three layers of foam with the addition of springs. There’s a breathable open cell foam, a high-density memory foam layer to support pressure points and a deep comfort adaptive transition foam layer to allow for even weight distribution and motion isolation, as well as the springs that give it a touch of luxury and bounce. It all comes wrapped in a zip-off easy-clean knit cover.

Overview of Emma

Emma was founded in Germany in 2015 and has made great strides since then, winning many awards for its signature Emma Original mattress.

The mattress is made up of three foam layers that work together to make one harmonious mattress. There’s a base polyfoam layer and a top Airgocell foam layer sandwiched between a middle memory foam layer. The Emma mattress has been designed to be both supportive and pressure-relieving for the perfect night’s sleep. It has also been created to be breathable, keeping you cool throughout the night.

The Emma Original washable elastic cover also has four handles, making it easy to manoeuvre into place so you won’t have to struggle.

Material comparison: Hybrid vs foam

One of the key differences between the Casper and Emma mattresses is the material they are made of. Although Casper has an original mattress made up of different layers of foam, just like the Emma mattress, Casper now also has a hybrid mattress, created from a combination of springs and foam. Check out the pros and cons of each type below:

Hybrid (Casper)

  • Springs adjust individually for motion isolation and allow extra airflow to keep you cool as you sleep
  • Casper’s has five spring zones with firmer support around the hip area and gentler support around the shoulders
  • Expect to pay more for Casper’s hybrid
  • Hybrid mattresses can be heavier and harder to move than pure foam
Memory foam (Emma)
  • Emma uses a breathable Airgocell foam layer to absorb moisture and keep you cooler
  • Memory foam contours to each individual’s body
  • Pure foam can be hotter than hybrid to sleep on
  • Pure foam has less bounce than hybrid

Trial periods and returns

Both Casper and Emma offer a 100-night trial period so if you don’t absolutely love your mattress after 100 nights you have the option of returning it. You’ll also get a full refund. Both companies also helpfully offer free returns so you don’t have to worry about being out of pocket on that front, either. Peace of mind all round.

Other items


Casper offers a mattress for pets, too! Alongside the original, essential and hybrid mattresses and pet beds, Casper also sells Casper pillows, cotton sheets, mattress protectors, bed frames and night lights.


As well as the Emma Original mattress, Emma also sells pillows. Shipping and returns on these standard size pillows are also free.

Online reviews

As online retailers without showrooms, both Casper and Emma exclusively rely on online reviews. Both companies advertise reviews made directly on their websites and show a star rating relating to the products and the quality of customer service.

The bottom line

Overall, the mattresses offered by Casper and Emma are relatively similar. The companies offer the same free trial period, free returns, 10-year guarantee, free delivery and UK-manufactured items. The main difference between them is that the Emma Original mattress is purely foam, whereas Casper’s new mattress is a hybrid. You’ll pay more for this but Casper does still offer an all-foam mattress if that’s what you’re after. Smaller differences include Emma’s 0% finance payment option as well as its slightly lower price while Casper offers a range of EU size mattresses.
