Choosing the right bed size

When looking to purchase a new bed or mattress, you must always take into account the size and shape. Beds that are too small will literally leave you with cold feet, beds that are too big may not fit your frame or leave no space in your bedroom.

What to consider

Quite simply you need a bed that suits your comfort and style requirements, but also that will fit into your room and most importantly into your house and bedroom! If you have an existing bedstead, divan or antique frame, you will need a mattress that matches its size and shape. At Hypnos we can make bespoke shapes and sizes on request.

Before you invest in your bed, Hypnos recommends asking yourself the following;

How big a bed do I need?

  • How tall are you? If you are slightly taller than average you may need to think about a bed with extra legroom to ensure you don't get cold feet. It's worth noting a king size bed is 10cm longer than a double or a single bed.
  • Is the bed for one or two people? If it's just for one at the moment, will it be for two in the future?
  • Is the bed for a child? Children tend to grow out their beds, so how long will your child fit in their current bed?
  • A larger bed gives you more space whilst sleeping and you are less likely to be disturbed by anyone sleeping next to you. A double bed gives each adult the same space to sleep as a small single.

How much space do I have?

When purchasing a new bed, you may be thinking about buying a bigger size. Having a larger bed has many perks, including more space to sleep in when sharing. However, it is worth carefully considering your space and how you use it.

  • Will it comfortably fit in the room with enough circulation space? Consider furniture doors and drawer openings.
  • What are your storage needs? Make use of the space under your bed - could under-bed drawers supplement or replace existing furniture.
  • Consider access to your bedroom - if you have small or spiral staircases to manoeuvre around.

Will I need to purchase a new bed base?

Your mattress is an investment in comfort and wellbeing, it needs to be properly supported to avoid being damaged. A broken or unsupportive base can invalidate your mattress guarantee and reduce its lifespan. Make sure no slats or boards are broken or bowing, and the gaps between slats comply with the manufacturer's recommendations.

Different countries have different standard sizes for beds, carefully check the size of your divan or bedstead when matching to your mattress. This is especially true of antique furniture.
