Do a few extra centimetres really matter? The answer is yes. That extra bit makes a huge difference. In a standard double bed, two adults each get just 67.5cm of space. Believe it or not, that is less than a baby gets in a cot.
Upgrade to a Pocket sprung mattress king size to add an extra 15cm of width. On paper, this may seem small, but in real life, it lets you sleep beside your partner, not on top of them. You get to pick your own sleep position. No more worrying about disturbing someone else.
A cramped bed keeps your body tense, making it harder to fully relax. Deep sleep is hard to reach because your brain stays alert when you feel boxed in. A king-size bed lets you breathe, move, and stretch.
Moreover, when you upgrade to more space, you remove that problem. Your own bubble makes falling asleep and staying asleep much easier.
A larger bed offers more comfort, not just extra size. A Sprung king size mattress carries a higher count of springs because the area is bigger, 150cm by 200cm. More springs mean more support in all the right places.
Each spring works independently. They do not tug each other down, unlike old coil systems. When you press on one area, the rest of the mattress stays steady. This is especially important when two people share a bed.
Picture sitting on a sofa where all the cushions move together. Someone sits, and you slide toward them. Bad mattresses work like that, but our pocket springs avoid that rolling effect.
| Feature | Benefit |
| Independent Movement | Less motion felt from your partner. |
| High Spring Count | Better support for every curve of your body. |
| Zoned Support | Heavier areas like hips get firmer springs; lighter body parts stay cushioned. |
If you have back pain, this customised support changes the game. The springs mould to your body, whether you sleep on your side or back. Need even more comfort? Try a Pocket sprung memory foammattress king size. The springs support you, while the foam gently cradles pressure points.
Worried that a bigger mattress means more heat at night? Sleepy Piglet ensures that it is never a problem. Overheating keeps many in the UK awake, especially in warmer months. To fight this, every mattress layer gets cooling technology and clever design.
We use breathable fabrics that let air flow throughout the mattress. Solid foam keeps heat trapped inside, but a King size pocket sprung mattress stays fresh. Springs form open channels, so with every move, warm air moves out, and fresh air comes in.
Old mattresses can double in weight over 10 years due to dust and dead skin. That is another reason Sleepy Piglet focuses on hypoallergenic fabrics.
This is not just for allergy sufferers. Everyone deserves cleaner air and a healthier sleep space, especially since you spend a third of your life in bed. Our materials form a shield, so you are not breathing in irritants every night. Choose natural fibres or a mattress with gel layers, and sleep easily knowing your health is protected every time you lie down.
Ready to order? Wait, and measure first. A king-size bed is big, and it needs room to fit and shine in your space. UK King Size is 150cm wide and 200cm long, or 5ft by 6ft 6in. Since this is a significant size, reach for a tape and check your bedroom carefully.
Do not just check the spot for the bed. Think about the entire room.
Sleepy Piglet delivers full-size, properly made mattresses. We never roll or squash our springs into a box. Rolling off makes springs weaker and hurts the mattress edge. Our flat delivery means your Sprung king size mattress keeps its shape and holds steady even at the sides. Before delivery, check the route from the door to the bedroom to ensure it will fit through every turn.
When a mattress is rolled into a box, edge support can be lost. Have you ever sat on the edge of a mattress and slipped off? That most often means the mattress was built for rolling. Sleepy Piglet keeps all borders and wires strong, so the bed holds you right to the edge and does not lose its support.
A king size pocket sprung mattress makes a real difference to how you wake up feeling every morning. The choice offers better support, deeper sleep, and more peace for couples, families, or even just someone wanting more space. And with our ten-year warranty and 100-night home trial, you have nothing to risk. You can try it for at least 30 nights so your body can adjust to the new comfort and support. If it is not the right fit for you, you can arrange a free exchange.
So choose your space and choose support. Check out our full range of Mattresses today and enjoy the comfort you deserve.
