What mattress sizes are best?

There are a number of mattress size conventions across the world. This post will detail all the UK sizes including mattress bases so you can see which bed will fit in your bedroom. The UK’s most popular mattress size is a king size which allows ample space for two people sleeping next to each other when compared to the snug fit of a double. Did you also know that if you’ve got restricted access, narrow staircases or low ceilings then you can get your mattress made as a zip & link model enabling practically any sized house to have the ultimate dream mattress!

The best mattress size is usually the largest bed you can comfortably fit. A king size for 2 people affords you a generous space regardless of your sleeping position without making the mattress impossible to turn. Larger sizes are usually better as a zip and link mattress which we stock in all our ranges.

We also offer a bespoke mattress making service so if you’ve got an unusual size requirement we can accommodate that too! Why not get in touch for the ultimate hand made mattress just for you!

Mattress Size Guide Approximations

Please be aware that unlike other manufacturers we don’t class the mattress cover in the overall mattress depth.  Other companies will add 1-3cm to the overall depth of the mattress using the cover and quilt undulations as part of the foam which we find misleading.  We don’t think this is a fair practice, so we don’t count this 1-3cm in the overall depth of the mattress.  Please be aware when choosing your mattress it may be slightly deeper than listed due to the cover and undulations. We advise you to wait until your mattress arrives before purchasing additional covers and sheets to make sure they fit.

Weights of Mattresses

This is an approximate guide for the weight of our Mattresses. Please be aware there is a sometimes a variance and we can’t guarantee an exact weight for the mattresses this is why we sometimes give a range. You need to know the weight of the mattress to check that you base can support it. Cheap mattresses may weigh as little as 20kg for a king-size whereas a hand made mattress full of Natural mattress fillings can weight up to 80kg! 

Under our Bespoke Service

  • Ikea Double 4’7” x 6’6”  (140cm x 200cm)
  • Ikea King  5’2″ x 6’6″ (160cm x 200cm)

Summary

We always recommend getting the biggest bed for the size of your room as this allows you the most freedom to sleep during the night. With smaller beds, you may find your partner disturbs you during the night. Zip & link models make an excellent choice for restricted access and offering completely customized spring tensions for each sleeper. They allow you the freedom of having a larger mattress size without worrying about it getting stuck up the stairs or not bending around a tight corner!
