How to Choose the Right Mattress Size?
Every product displayed at Luxe Mattresses UK has clearly mentioned size options in the size chart. But most customers don’t know which mattress size is suitable for their needs. Here are some practical tips that can help you choose the right mattress size.
1. Measure Space in your Bedroom
There is no hard and fast rule but it is advised to leave 60cm of space around your bed for easy movement in the room. Start with measuring the size of your room. A super king bed may not fit inside a small room. If a queen-size mattress can accommodate you, there is no need to get a bigger bed.
2. Who will use the Bed?
In a home, different people will use beds and mattresses. Different mattress sizes are available for different sleepers. Here is the right way to determine the mattress size based on the person sleeping on it:
Couples: a queen-size mattress is the bare minimum for couples. King or super king mattresses might also be comfortable if your kids or pet sleep with you.
Solo sleepers or teenagers: a small double bed will not take up too much space in your room and you still have space to stretch around.
Children: Single or small single mattress is good enough for kids
3. Consider Future Needs
If you are planning for a long term, buy a mattress that can be used for years. Kids grow quickly and buying a toddler bed will require a new bigger mattress pretty soon. Other lifestyle changes should also be considered.
