How to Choose the Right Mattress Size?
With different size options available for mattresses in the UK, how do you determine the right size for your room? Here are some points that can help you in the decision-making process.
1. Room Measurements
Bedroom size is one of the most important factors in deciding the right size for a new mattress. For a smaller room, a king-size mattress may be too big. Queen mattress is the ideal size option for smaller rooms. Placing a king bed will look good in bigger rooms only.
2. Budget
Looking for the right bed without setting a budget will make the purchase process confusing for you. First things first, set a budget for the mattress, then start analysing the options.
A king mattress is more expensive than a queen mattress. Can you afford more money on a bigger mattress? For customers on a tight budget, queen mattresses may be a more affordable option.
3. Sleeping Partner
Are you a solo sleeper? Or do you sleep with your partner and kid? A queen mattress is good enough for a couple. Actually, most couples in the UK prefer queen-size mattresses. The king mattress is only needed if your kid or pet sleeps with you in the bed, or your partner takes up too much space in the bed.
4. Sleeping Habits and Body Features
The physical size of the sleepers is also an important factor in the process. For two bulky and oversized sleepers, a queen mattress may feel cramped. If your partner is a combination sleeper and keeps changing sides, you need a king-size mattress.
Conclusion
In the UK and Europe, a queen-size mattress is smaller than a king-size mattress. There are slight differences in the dimensions of beds in the UK and the EU. Make sure to confirm the size of the mattress before making the purchase.
