Explore our King Size Bed Styles

At Simba, we sell king size beds in a variety of designs and styles to suit different interiors and personal preferences. When you browse through our king size bed collection, you’ll come across:

Upholstered King Size Beds

Our upholstered king size beds are a great choice for people who want to create a more inviting and relaxed sleeping environment. Every king bed that you’ll see in our upholstered collection has been wrapped in luxury fabric that looks great and is very soft to the touch.

Our upholstered king beds are also available in many different styles, designs, and colours, giving you plenty of flexibility to choose a model that suits your room and aesthetic preferences

Wooden King Beds

Every Simba wooden king bed is made using the highest quality UK Timber Regulated (UKTR) Ash wood or American Oak. The use of natural materials not only gives our wooden king beds the sturdiness and durability they are known for, but also brings a sense of warmth and character into your bedroom.

King Beds With Storage

Our king beds with storage are ideal for people who want their large comfortable bed to double as a source of extra storage space. Each of our king beds with storage has compartments that sit beneath the base of the mattress.

Some of the storage configurations that our king beds are available in include Ottoman, 2 Drawer, and 4 Drawer.

Metal King Beds

Our metal king beds feature a slim, yet hard-wearing structure that maintains its strength over time. This makes any Simba metal king bed a durable and long-lasting option that is particularly well-suited to bedrooms where preserving a sense of openness is important.

How to Choose the Right King-Size Bed

To choose the right king size bed, there are three main factors that you need to take into consideration. They include:

Room Size

Due to the wider frame of a king size bed (compared to a standard double bed), you need to make sure that the bed can comfortably fit in the room that you plan to place it in. Once the bed is installed and ready to use, it shouldn’t make your space feel cramped or obstruct access to other furniture.

The good news is that king size bed frames can vary in length, width, and height. So, if you’re working with a limited amount of space, you can opt for a more compact frame design or a king size bed with a lower profile.

Storage Needs

Some king size beds feature built-in drawers or an ottoman lifting mechanism, which will help you maximise the space beneath the mattress that would have otherwise gone unused. So, if you’d like extra storage space in your bedroom, consider choosing a king size bed with storage.

At Simba, we have plenty of king size beds that will allow you to keep your bedding, clothing, and everyday items neatly organised and out of sight. Some of our most popular king size beds with storage include the Didsbury, the Hoxton, and the Camden.

Material & Style

Before you settle on a particular king size bed, take into account its overall style and the material it’s made from. This is important as the material and style of the king size bed you choose will affect both how it fits within your space and how it performs over time.

At Simba, our line of king size beds features models in many different styles and designs to suit different aesthetic preferences. As far as materials are concerned, you’ll come across king beds that are made of the highest quality wood, metal, and upholstered fabrics.

Why Buy a Simba King Size Bed?

At Simba, we design each king size bed frame with three goals in mind - to look great in your space, last a very long time, and provide support that you can depend on night after night. In addition to the above, other reasons why you should buy a king size bed from Simba include:

  • You can trial your Simba king size bed for 200 nights
  • Every bed from our king size range is made in the UK
  • We offer an industry-leading 10-year guarantee on all our beds
  • Our king size beds are available in many different designs and colours
  • We will deliver your new Simba king size bed completely for free
  • You can configure your king size bed frame to a great extent
  • We offer flexible finance options

  • What room size do I need for a king size bed?

    There is no minimum room size requirement for a king size bed. What you need to consider is whether your bedroom can comfortably accommodate the frame of the bed that you like without restricting movement or access to other furniture.

  • What size is a king size bed?

    King size beds don’t come in a standard size. The actual size of a king size bed will vary depending on a number of factors. They include the design of the frame, the height of the base, the structure of the headboard, and a handful of other factors.

    With that being said, all king size beds are intended to fit a UK standard king size mattress, which measures 150cm (W) x 200cm (L). So, when it comes to the actual size of the bed frame, it doesn’t make a difference - just make sure the room you plan to place the king size bed in can comfortably accommodate it.

  • What is the difference between a king and a super king?

    The main difference between a king size bed and a super king size bed is the width. A standard UK king size bed is designed to fit a mattress that measures 150cm (W) x 200cm (L), while a super king size bed is built to fit a mattress that measures 180cm (W) x 200cm (L).

    This additional 30cm of width provides more personal space, which can be particularly useful for couples who’d like to have more room to move around throughout the night.

  • Do Simba king size beds come with a mattress?

    No, Simba king size beds are sold without a mattress. If you’d like to buy a Simba king size bed with a mattress, when you choose the bed that you want to go with, you will be presented with an option to add one of our award-winning mattresses to your order.

    You can also create a bundle and choose the exact Simba bed and mattress that you’d like to go with.

  • What duvet size do I need for a king size bed?

    A king size bed is most commonly paired with a king size duvet, which measures 225cm x 220cm. A duvet of this size is wide and long enough to provide enough coverage on both sides of the bed throughout the night.

    It’s also not uncommon for people with a king-size bed to opt for a super king duvet, as it naturally provides even more coverage.

  • Can I try a Simba Bed before buying?

    Yes, you can try a Simba bed before you buy it. Our king-size beds can be found in the showrooms of Bensons for Beds, Barker and Stonehouse, and John Lewis throughout the UK.

    If visiting a showroom isn’t a convenient option for you, you can also take advantage of our 200-night trial. It allows you to test your king-size bed for a total of 200 nights, and in the rare case that it doesn’t meet your expectations, we’ll come and pick it up completely free of charge.
