How to choose the best king size mattress for you

How big is a king?

A standard king size mattress measures 150cm by 200cm, while a double mattress measures 135cm by 190cm. It goes without saying that if you are upgrading from a double mattress, you need to make sure you have enough space to accommodate a king size bed.

It’s also worth mentioning that king size mattresses are 10cm longer than single and double beds, so you might want to invest in a king size bed if you’re particularly tall.

Is there anything else I should consider?

Whether you’re looking for a single, double, or king size mattress, there are a number of important factors to consider when shopping for a new mattress. As such, we encourage you to check out our dedicated mattress buying guide, as well as some of the other pages listed below:

The best king size mattresses to buy

1. Emma Original: The Best Memory Foam Mattress for Couples

Price: £799 (king size) | Shop now at Emma

The Emma Original is our top pick for couples thanks to its versatility: the brand’s all-foam mattress is extremely comfortable for sleeping in a range of positions. So if you sleep on your side while your partner prefers to sleep on their back, you don’t have to worry about finding a compromise.

Admittedly, the Emma Original is quite soft compared to some of its bed-in-a-box rivals, and since it’s an all-foam mattress, it might not be the best choice for those who are very hot in bed. Nevertheless, the Emma Original offers great levels of comfort and support. It is well suited to any type of bed base (spring or solid slats) and does not need to be turned or turned. You’ll also get a 200-night trial with a money-back guarantee if you find the Emma Original isn’t for you.

Key Features – Type: memory foam; Need to spin? Nope; Sizes: Single to super king (including European sizes); Guarantee: 10 year warranty, 200 night trial with money back guarantee

2. Simba Hybrid Pro: The Best Hybrid Mattress

Price: £1,529 (king) | Buy now from Simba

One of our favorite hybrids, the Hybrid Pro sits in the middle of the Simba mattress range (between the regular Hybrid and the Hybrid Luxe). It’s constructed from a combination of foam, two layers of micro pocket coils and a British wool comfort top layer (which also helps keep you cool at night).

The king-size Hybrid Pro costs a little at £1,529. However, it’s worth pointing out that like most bed-in-a-box mattresses, you get an extended trial period (200 nights), at the end of which you can return it for a full refund if you are not satisfied. this. Plus, we’d say such a comfortable and supportive mattress is well worth the price.

Key Features – Type: Hybrid wool, foam and pocket micro-springs; Need to spin? Rotation once a month for the first six months; once every 3/6 months thereafter; Sizes: Bachelor to King; Guarantee: 10 year warranty, 200 night trial with money back guarantee

3. Silentnight Studio Eco: The best budget hybrid

Price: £509 | Shop now at Silentnight

If you’re looking for something more affordable (after all, not everyone has the budget to spend over £1000 on a new mattress) then the Silentnight Studio Eco is a decent choice.

In addition to being cool and comfortable, you can also argue that the Studio Eco hybrid mattress is more environmentally friendly than memory foam models. Instead of using polyurethane plastic which is the key ingredient in memory foam, it’s made from recycled synthetic fibers with a layer of full-size pocket coils.

The main downsides are the lack of on-board support and a disappointing trial period (a 60-night comfort swap), but the Studio Eco is a sensible budget choice nonetheless.

Key Features – Type: Recycled synthetic materials and pocket springs; Need to spin? Rotation once a month for the first few months; Sizes: Bachelor to King; Guarantee: 5-year warranty, with 60-night convenience exchange trial

4. Eve Premium Hybrid: Best for reducing motion transfer

Price: £1,128 (king) | Shop now at Eve

Of Eve’s extensive line of mattresses (the bed-in-a-box brand has no less than six foam and hybrid mattresses), we found the Premium Hybrid to be the best. Like the Emma Original, it’s a great choice for couples, largely due to its ability to reduce motion transfer. This means you can sleep soundly even when your partner is tossing and turning during the night.

Beyond that, the Premium Hybrid offers an excellent balance of comfort and support. Eve also recently extended its mattress trial period from 100 nights to 365 nights, meaning you can try it out for a full year and return it for a full refund if it isn’t right for you.

Key Features – Type: Hybrid foam and pocket springs; Need to spin? Rotation approximately once a month; Sizes: Double to super king; Guarantee: 10 year warranty, 365 night trial period with money back guarantee

5. Brook + Wilde Elite (Medium): Best for Side Sleepers

Price: £1,299 (king) | Shop now at Brook + Wilde

While well-suited to all sleeping positions, we found the Brook + Wilde Elite in size medium to be a great choice for side sleepers, in particular. Among its six layers of foam and mini pocket springs is a layer of “wave technology” foam, the curvature of which is designed to give the right level of support to the right areas.

If you’re not a side sleeper, Brook + Wilde stands out from its bed-in-a-box rivals in that it also offers a choice of firmness options. Indeed, in addition to the average “feel” we tested, it also comes in soft and firm options. At £1,299 for a king size, it’s only slightly cheaper than the Simba Hybrid Pro, but you also get a 100-night comfort trial with a money-back guarantee.
