Leesa vs Sleeping Duck

Leesa and Sleeping Duck mattresses are part of the new revolution in advanced foam mattresses. In this guide, we'll be comparing the two brands, and seeing which is more suitable for your needs.

Sleeping Duck Mattress Leesa Mattress

Prices and sizes

Both mattresses come in a range of UK and EU sizes, with the largest size being a super king. The Leesa mattress is slightly more expensive than the Sleeping Duck mattress.


The Leesa mattress has four layers to Sleeping Duck's five. However, the Sleeping Duck mattress is unique in that it offers an interchangeable top layer. This can be set to either a medium or hard firmness rating, or even half and half. Let's take a look at the layers in more detail:


  • Cover – A blend of polyester and lycra, woven with a special machine that makes it seamless.
  • Top Layer – A 5cm cooling Avena (latex) foam, which is both hypoallergenic and fire retardant.
  • Middle Layer – A 5cm memory foam layer for comfort and moulding to the body.
  • Bottom Layer – A 15cm dense core support foam. This is the foundational layer for the mattress, helping it keep its shape.

Sleeping Duck

  • Cover – A two-tone white and grey cover, made from a blend of rayon from bamboo on the top and polyester side panels. The cover is also completely removable.
  • Top Layer – A 1.9cm latex foam layer, designed to provide most of the cooling, bounce and comfort.
  • Second Layer – A 1.9cm memory foam layer, which works with the top layer to create pressure relief and contouring.
  • Third Layer – A 6.4cm of polyfoam, to aid pressure relief and provide support. The polyfoam also acts as a transitional layer.
  • Bottom Layer – A 21.6cm of pocketed coils, providing deep compression support and the foundation for the mattress as a whole.

The Leesa mattress is 25cm in depth, whilst the Sleeping Duck is a whopping 30.5cm in depth. As you can see, they are constructed in a very different fashion.

Firmness, Comfort and Support

The Leesa mattress has a medium firmness rating. As discussed previously, the Sleeping Duck mattress can have either a medium or hard firmness, or half and half. Let's look at the pros and cons of each mattress in this department.


  • Moulds extremely well to each sleeper's unique body form, due to the Avena foam combined with pressure relieving memory foam.
  • Minimal sinkage from the Leesa, meaning that whilst you are always supported, you don't feel stuck in the mattress.
  • One of the most breathable and cool foam mattresses on the market.
  • Struggles a little with edge support, but this is fairly standard with any foam mattress.

Sleeping Duck

  • The Sleeping Duck is notable for its ability to keep sleepers cool and does not retain any heat.
  • The layer of microcoils help to create a good level of sinkage without any pressure points being created, and the 5-zone system means that the mattress adapts quickly to any sleeping position.
  • The hybrid design of the mattress means that the mattress has a good level of bounce, as well as good motion transfer.
  • The contour and hug of the Sleeping Duck provides a great mix of sinkage, contour and support.

Other factors

Both companies come with a 10-year guarantee and a 100 night trial period. If you're not satisfied, both will offer a full refund. The mattresses both have free delivery and arrive compressed in a box. Leesa also run a programme to help improve communities around the United States, and donate 1 mattress for every 10 they sell.

Which mattress is best for me?

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


We'd recommend this mattress if:

  • You want a high quality mattress for a budget price. The Leesa performs well against far more expensive mattresses, such as Tempur.
  • You want a mattress that keeps you cool. The airflow of the top layer, combined with the breathable cover makes for exceptional cooling.
  • You want a mattress that is equally comfortable in any sleeping position.
  • You like a light bounce across the mattress, helping to keep it comfortable and responsive.

Sleeping Duck

We'd recommend this mattress if:

  • You want a cheaper alternative to the Sleeping Duck mattress.
  • You want to be able to choose between medium and firm mattresses, as well as having the chance to trial both options.
  • You want a hybrid mattress. The hybrid design provides great support, cooling, edge support, response and bounce and is still very reasonably priced.
  • You want a cooler mattress that stays cool and comfortable throughout the night.
  • You want a supportive mattress that adapts quickly and doesn't allow any pressure spots to form.
