Kingsize Sleepsoul Mattresses

A kingsize bed and mattress are designed to accommodate two people, allowing plenty of room and providing people taller than 190cm with more space. Measured in metric units, a king size bed and mattress is 150cm wide and 200cm long. Converted to imperial units, a king size bed and mattress is 5 feet wide and 6 feet 6 inches long. A standard ‘King Size’ (5’0”) bed includes a longer length than the standard ‘double’ bed and mattress - 6’6” instead of 6’3”.

Mattress Buying Guide

What is the best type of mattress?

Each type of mattress has its benefits, firmness, and feel. As each body is different, it is important to know your sleeping needs to choose a mattress that can provide you with the best support and comfort.

When choosing a mattress, you should think of your sleeping circumstances, the level of support you need, and the feeling you want to achieve. If you want a traditional mattress with natural fillings offering great support, then a pocket spring mattress might be the right choice. A memory foam mattress might be your best choice if you need a mattress to help alleviate back pain.

When it comes to firmness, the most important thing is to choose a mattress that you feel comfortable on.

What should I consider when choosing a size?

  • Number of Sleepers: If you're sharing the bed with a partner or spouse, it's generally recommended to choose at least a double-sized mattress or larger for adequate space and comfort.
  • Bedroom Size: Measure your bedroom to ensure that the selected mattress size fits comfortably, allowing space for other furniture and easy movement around the room.
  • Personal Comfort Preferences: Consider your own sleeping habits and preferences. If you tend to move around a lot during sleep, a larger mattress may provide more comfort.
  • Guest Accommodations: If the mattress is for a guest room, consider the typical guests you'll host. A double or king-size mattress can offer flexibility for accommodating couples or individual guests comfortably.
  • Budget: Larger mattresses generally come with higher costs. Set a budget that aligns with your needs and preferences while considering the overall cost, including bed linens and accessories.
  • Room Layout: Consider the layout of your bedroom, including the placement of doors, windows, and other furniture. Ensure the mattress size allows for a balanced and aesthetically pleasing arrangement.

Remember that individual preferences and needs vary, so the best mattress size for you will depend on your specific circumstances. If possible, try out mattresses in a showroom or take advantage of trial periods offered by mattress retailers to determine the most comfortable size for your sleep habits

How do I choose a mattress?

Sleeping on a supportive base is essential for a good night's sleep. Before purchasing, it is important to research what mattress is best for your individual sleeping needs. When you shop for a mattress, you should consider the following: mattress firmness, your sleeping position, your weight, special needs (joint pain, back pain, allergies, asthma), and your budget.

Which mattress size should I get?

Choosing the right mattress size depends on several factors, including the number of people using the mattress, the size of the bedroom, and individual preferences. Here are the standard mattress sizes and considerations for each:

  • Single Mattress (3 feet x 6 feet 3 inches / 90 cm x 190 cm):
    • Ideal For: Children's bedrooms
    • Ideal For: Guest rooms with limited space
    • Ideal For: Individuals with smaller bedrooms or those who sleep alone

  • Small Double Mattress (4 feet x 6 feet 3 inches / 120 cm x 190 cm):
    • Ideal For: Individuals who want more sleeping space than a single bed
    • Ideal For: Guest rooms accommodating one adult comfortably

  • Double Mattress (4 feet 6 inches x 6 feet 3 inches / 135 cm x 190 cm):
    • Ideal For: Couples with limited space
    • Ideal For: Individuals who enjoy more sleeping space
    • Ideal For: Guest rooms accommodating couples occasionally

  • King Size Mattress (5 feet x 6 feet 6 inches / 150 cm x 200 cm):
    • Ideal For: Couples who want extra space
    • Ideal For: Larger bedrooms with ample space
    • Ideal For: Individuals who prefer more room while sleeping

  • Super King Size Mattress (6 feet x 6 feet 6 inches / 180 cm x 200 cm):
    • Ideal For: Couples who want maximum space
    • Ideal For: Larger master bedrooms with spacious layouts
    • Ideal For: Individuals who prioritize a spacious sleep environment

What is the healthiest type of mattress?

The healthiest mattress provides you with the right amount of support and comfort. Memory foam and pocket springs offer the most benefits as these systems help keep your body properly supported, leading to a more regenerative and deeper sleep. This, in turn, will help make you feel refreshed and recharged when you wake each day. Sleepeezee mattresses have a range of hybrid mattresses encompassing both pocket springs and memory gel, offering the best of both worlds for comfort and support.

How do I choose the right mattress firmness?

The right mattress firmness depends on your body shape, weight, sleeping position, and preferences. We offer a wide range of mattress firmness from soft to firm that you can find in our "By Comfort" Section.

If you are a back sleeper, you should opt for a medium-firm mattress. As a side sleeper, you should try a medium-feel, and as a stomach sleeper, a firm mattress might be your best option.

How do I dispose of an old mattress?

We are highly committed to protecting the environment. Therefore, we offer a Disposal and Recycle Service. We can collect your old mattress as soon as we deliver a new one, rest assured that we will dispose of your old mattress in an environmentally friendly way.

What mattress brands are available?

There are numerous mattress brands available, offering a wide range of options in terms of materials, construction, firmness, and price points. The popularity and reputation of mattress brands can vary based on customer reviews, industry recognition, and personal preferences. Here are the brands currently available:

  • Breasley
  • Dormeo
  • Giltedge
  • Millbrook

What are the different types of mattresses?

Open Coil Mattress

The open coil mattress is a popular budget option that contains one long piece of metal wire coiled into numerous springs. They are the most common type of mattresses, but with the new industry innovations, they tend to be less supportive than other mattresses.

Pocket Spring Mattress

Made from individual springs housed in their fabric pocket, providing more support than open coil mattresses.

Memory Foam

Made from memory foam, a mouldable material that responds to temperature and weight and has hypo-allergenic properties.

Latex Mattress

Filled with latex foam, this mattress is breathable and prevents overheating. They are also good for those suffering from allergies or asthma.

Hybrid Mattress

A combination of pocket springs and other materials such as memory foam or latex. They often come as a pocket spring base and a memory foam layer, combining comfort and support.
