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 take into account

When choosing a new bed, there are a few considerations to think about before making a purchase. Buying a bed without taking the following into account could leave you unhappy with your new bed, causing you to start again.

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

How much space 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. A king size bed is 10cm longer than a double bed.
  • Is the bed for one or two people? If it 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?

How much space do I have?

When purchasing a new bed, you may be thinking about upscaling and purchasing a bigger size. Having a larger bed has many perks, including more space to sleep in when sharing. Unfortunately, you may not have space in your bedroom to size up, so you should always do some checks before purchasing.

  • Do you have extra width?
  • Do you have extra height?
  • Do you need a storage compartment?

Will I need to purchase a new frame?

When buying a new mattress, you need to think about your current frame. Bed sizes are made to ift a UK standard, but upsizing your mattress means purchasing a new frame to fit it.

If you are purchasing a frame, it is good to remember that all UK bed and frame sizes match. By that, we mean that a double mattress will always fit a double frame. There is no need to factor this part into purchasing if you are buying a Divan bed as it is an all-in-one solution.
