King Size Mattresses

We know that in the UK, getting a good night's sleep is sometimes easier said than done. Maybe you are fighting over the duvet cover, or perhaps you just need more room to stretch out after a long day. If your current bed feels a bit like a squeeze, upgrading to one of our King Size Mattresses could be the answer you have been looking for.

Sleepy Piglet believes everyone deserves a proper rest. A standard double is often just not enough for two adults to sleep without bumping elbows. A king-size mattress gives you that extra bit of luxury and space, so you can finally enjoy your own sleeping zone. We handcraft our mattresses right here in the UK. This ensures you get top-notch quality without the worry of overseas shipping delays or varying standards. On top of that, we offer a risk-free 100-night trial. So, you can test your new bed at home to make sure it is the perfect fit.

King Size Mattresses: Explore Our Extensive Collection

We have curated a range that caters to all sorts of sleepers. You might prefer the bounce of springs or the hug of memory foam. Our collection of king-size bed mattress options is designed to suit different body types and comfort preferences.

What You Can Expect From Sleepy Piglet

We keep things simple. We don't use gimmicks like "mini springs" that just add cost without adding comfort. Instead, we focus on genuine support layers. You will find:

• Pocket Spring Models: These contain individually encased springs. They move independently to support your body where you need it most.
• Hybrid Models: These mix springs with memory foam, so you get the airflow of springs with the pressure relief of foam.
• Natural Fillings: For those who want a chemical-free sleep, we use wool and cotton.

You can browse our other collections, too, if you need a different size. We have Single Mattresses for guest rooms and Double Mattresses for smaller master bedrooms. But if you have the space, a mattressis truly the way to go for maximum comfort.

Choosing the Right King-Size Mattress

Selecting a king-size mattress involves more than just picking the softest one. You have to think about your room, your partner, and how you actually sleep.

Check Your Room Size

In the UK, bedrooms aren't always massive. A king size bed is 5ft wide (150cm) and 6ft 6in long (200cm). Before you buy, you should grab a tape measure. You need enough space to walk around the bed comfortably. You might want to leave at least 60-70cm of space around the sides for bedside tables and wardrobe doors. If your room is a bit tight, Small Double Mattresses might be a safer bet. But if you can fit it, the extra space on the bed is worth sacrificing a bit of floor space.

Your Sleeping Style

How do you sleep? This changes everything.

• Side Sleepers: You likely need a bit more cushion for your hips and shoulders. A king size medium soft mattress could be ideal.
• Back Sleepers: You need support to keep your spine straight. A medium firm king size mattress often works best.
• Stomach Sleepers: You need a surface that doesn't let your hips sink. A firmer option is usually necessary.

Partner Disturbance

If you share your bed, you know the struggle of waking up every time your partner moves. Our King Size Mattresses use pocket springs or foam to stop this "motion transfer." So, if they toss and turn, you stay asleep.

King Size Mattress Options

We offer a variety of feels because no two sleepers are the same. You can find everything from a firm, supportive surface to a cloud-like pillow top.

The Firm Mattress

A king size firm mattress is fantastic for those who need robust support. It is often recommended for heavier individuals or those who sleep on their front. It keeps your body floating on top of the mattress rather than sinking in. It also helps with airflow, keeping you cooler.

The Medium Mattress

Most people get on well with a medium king size mattress. It sits right in the middle and offers enough give to be comfy but enough push-back to support your back. It is the "Goldilocks" option for couples with different sleep styles. If you aren't sure what you need, this is often a safe starting point.

The Soft Mattress

For a truly luxurious feel, you might consider a king size medium soft mattress. These often have pillow tops or deep layers of wool. They are brilliant for side sleepers who wake up with aching shoulders. It feels a bit like sleeping on a cloud.

Benefits of a King Size Bed Mattress

Why should you upgrade? It is a fair question. Moving from a double to a king size mattress is a significant change.

1. More Space Per Person
   In a standard double bed, each person only gets 67.5cm of width. That is less than a baby has in a cot! In a King, you get 75cm each. It might not sound like much, but that extra room makes a huge difference. You can stretch your arms out without hitting your partner in the face.
2. Better Length for Taller Sleepers
   Standard UK doubles are 190cm long. If you are over 6ft tall, your feet probably hang off the end. A king size bed mattress is 200cm long. Those extra 10cm mean your toes stay warm under the duvet.
3. Reduced Overheating
   Sharing a small bed means sharing body heat. If you or your partner runs hot, being squashed together makes it worse. A bigger bed allows for more air circulation between you.
4. Less Disturbance
   We mentioned motion transfer earlier. A bigger surface area naturally reduces the vibrations you feel from the other side of the bed.

King Size Mattress Materials

What goes inside your mattress matters just as much as the size. We use high-quality materials to ensure durability and comfort.

Pocket Springs

Our king size pocket spring mattresses use between 1,000 and 3,000 individually wrapped springs that respond to your weight and movement, providing targeted support and excellent motion isolation.

Memory Foam

We often pair memory foam with springs in hybrid designs, so you get that gentle “melting” pressure relief without feeling stuck, along with better airflow than in older solid foam mattresses.

Natural Fillings

For our King Size Mattresses in the natural range, we use organic cotton and wool. These breathable fibres help wick away moisture and naturally resist dust mites, creating a fresher, more comfortable sleep surface.

Understanding Mattress Firmness for King Size Beds

Firmness can be confusing to many people. Therefore, we try to keep our scale easy to understand. Using the right firmness for your body weight is crucial for spinal alignment.

If you are dealing with back pain, a supportive medium firm or firm king size mattress is usually a better choice. It helps keep your posture healthier while you sleep.

Where to Buy a King Size Mattress

You could trudge around a showroom, awkwardly lying on beds while a salesperson watches you. Or, you could order from Sleepy Piglet and try it properly.
