Overview of Leesa

The original idea behind Leesa was to simplify the whole mattress concept. The founders of Leesa said they wanted to take out all the “stuff” that traditional mattress companies had been adding to justify higher prices and get back to a simple, quality mattress with a lower price point.

The mattress has three simple layers. The base of the mattress is made from 15cm of core support base foam to combat the sinking problem of traditional foam mattresses; the centre layer is made from 5cm of contouring memory foam to give the mattress an adaptive feel, and the upper layer is made from 5cm of cooling Avena foam, to provide bounce and a cool sleep surface.

For every 10 mattresses sold, Leesa says it will donate one to someone in need.

Overview of Simba

Simba started as a thread shop and began its mattress design journey in 2002. Since then more than 1 million mattresses have been sold, and its “bed in a box” mattress has given Simba a secure position among the top UK mattress brands.

The current Simba mattress is a hybrid – combining individual pocket springs and responsive memory foam. Formed from five layers, Simba is designed to give you a great night’s sleep whatever your sleeping style. One of these five layers is Simba’s super-comfort layer “Simbatex” to ensure that the mattress stays cool throughout the night.

Material comparison: Hybrid vs foam

One of the key differences between the Leesa and Simba mattresses is the material they are made of. Leesa is crafted purely from layers of different foams, whereas Simba is a hybrid mattress, made from a combination of pocket springs and foam. Check out the pros and cons of each type below:

Memory foam (Leesa)
  • Leesa uses a combination of foams to create contouring pressure relief without the traditional foam ‘sinking feeling’
  • Memory foam contours to each individual’s body to give a personalised sleep
  • Pure foam can be hotter than hybrid to sleep on
  • Pure foam has less bounce than hybrid
Hybrid (Simba)
  • Pocket springs adjust individually for motion isolation
  • Springs allow extra air flow to keep you cool as you sleep
  • Simba’s springs are more shallow than traditional hybrids so the effects might not be the same
  • Hybrid mattresses can be heavier and harder to move than pure foam

Trial periods and returns

Both Leesa and Simba offer a 100-night trial period so if you don’t absolutely love your mattress after 100 nights you can arrange to return it and receive a full refund. Both companies also offer free returns so you don’t have to worry about being out of pocket, either.

Other items

Leesa

The Leesa mattress is still Leesa’s premier product, but it also sells a Leesa Sheet Set made from sateen weave and boasting a 500-thread count, and a Leesa Pillow with a micro-fibre outer fill and temperature-regulating memory foam middle. The Leesa Sheet Set comes with a 75-night free trial and the Leesa Pillow comes with a 100-night trial, just like the Leesa mattress.

Simba

As well as the hybrid Simba mattress, Simba also sells a Simba duvet, Simba pillows, bed frames and sheets. Shipping and returns on accessory orders are also free and the accessories come with guarantee of either one or three years.

Online reviews

As online retailers without showrooms, both Leesa and Simba rely on online reviews. Both websites showcase user reviews that are left directly on their websites, with Leesa stating that the shown reviews come from customers in both the UK and the USA.

The bottom line

Overall, the mattresses offered by Leesa and Simba are quite similar. The companies offer the same free trial period, free returns, 10-year guarantee, free delivery, UK-manufactured items and the option of finance. The main difference between them is that the Leesa mattress is purely foam, whereas Simba’s mattress is a hybrid. As Leesa mattresses are made to order they also have a longer delivery lead time than the Simba equivalent.
