The mattress industry is a huge and often confusing business. There is a wide range of different materials, types and sizes. To help make your job easier we have put together a list of the top bed in a box mattresses for 2020. 

The bed in a box mattress market has rapidly grown in the past few years and due to several reasons, it has become a customer favourite. A bed in a box mattress is often ordered online and delivered in a small box. The mattress is vacuum packed inside to save space. This allows for cheaper delivery costs, reducing the price you are paying. 

They also usually offer a generous trial period, allowing you to send the mattress back for a full refund if you do not like it. The warranty is usually for a longer time than is standard as well.

We have chosen some of our favourite mattresses from the leading contenders in the bed in a box mattress market. They have won a wide range of awards and are from well-known companies with solid reputations. We have selected a mix of hybrid and memory foam mattresses with a range of different prices to suit all budgets. If you are unsure of which will suit you best, read our extensive mattress buyers guide. Any spring amounts are the amount that is found within a double mattress, any other sizes may be slightly different. 

Here is our guide for the top bed in a box mattress for 2020, mattresses are not in a ranked order as they all offer different features and will suit different people depending on their needs.

Casper Hybrid Mattress

This addition to the bed in a box mattress market is a very strong offering. It has similar construction and general feedback to mattresses that are much higher in price.

The Casper Hybrid mattress is highly adaptable, suiting a wide range of sleepers. This is especially useful for couples who sleep in different ways. The 5 different layers that are a combination of pocket springs and foam provide a great amount of support and comfort. The top layers adapt quickly and easily to your sleeping position, keeping you comfortable and the pocket springs provide a great bounce. The extra edge support on the mattress also allows you to make the most of the full area of the mattress.

As with many mattresses on this list, the Casper hybrid is a great choice for couples with a small amount of motion transfer and noise transfer across the mattress. 

The mattress is very adaptable to sleeping positions though heavier sleepers may want a bit more support when sleeping on their stomach. This is one of the tradeoffs of it being a slightly softer mattress. The extra softness does not feel you leaving stuck in the mattress though as it is only the very top layers that are soft and they quickly mould around the body adding to the comfort the mattress provides.

Considering all factors that can affect sleep, we have rated this mattress 9.1/10

Pros and Cons



100-night trial
May sleep too warm
Free delivery and returns
Limited payment options
High level of edge support
Pricier than other similar mattresses

The Simba Hybrid is available directly from Simba, but also available on Amazon and through physical retailers such as John Lewis. The only real problem to be found with it is the lack of handles.

On the support side of the Simba Hybrid, it comes with free delivery and a 100-night sleep trial. It also comes with a 10-year limited warranty. While this is now becoming the standard for bed in a box mattresses it is still good to have and gives extra peace of mind knowing you have it.

The Eve Original mattress is a well-known memory foam mattress and has been proven to provide a great night’s sleep. While it is relatively simple in design, it does it very well which is the main reason it makes it onto our top 6 bed in a box mattresses. The Eve Original mattress is made from 3 different layers of foam, each designed to work with each other to provide different features of the mattress.

 The mattress is medium-firm and designed to suit all sleepers. This is done by providing a great balance between support and comfort. The mattress provides great support to your major joints, preventing your hips and shoulders from sinking too far, allowing you to maintain good spine alignment.

This mattress is great for couples, due to its all-foam construction. This results in it having great levels of motion and noise isolation meaning you will not be disturbed by your partners’ movements during the night.

A common problem with memory foam mattresses is them sleeping too warm. Eve Sleep claims the foam used in the Original has 30 times the cooling effect over traditional memory foam but it is still something to keep in mind.

As is mostly standard with Eve sleep mattresses, this mattress comes with a 100-night trial so you can get a full refund if it does not suit you. In addition to this, it comes with a 10-year limited warranty.

A downside of this mattress is that it is not available in any EU sizes and so it is best to check if you have a UK base before ordering this mattress.

Considering all factors that can affect sleep, we have rated this mattress 9/10.
