Zip and link beds are idea for differently weighted sleepers or if you want to be able to divide the bed periodically. Zip and links also make turning your mattress far easier.

Zip & link mattresses offer a number of benefits including split tension spring units if you and your partner require different tensions in your bed. The zips are recessed so you won’t feel them and it makes turning your mattress far easier each month. We have a very handy guide below to explain exactly how zip and link mattresses work which may be of interest.

What mattress & bed 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 mattress 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. Kingsize mattresses are the most popular in the UK.

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.

Mattress Size Vs the Bed Frame Size

When choosing a new mattress you also need to consider the mattress base that it will sit on. In particular, if it will fit into both your bedroom and also up the stairs!

Your mattress size should always correspond with the bed size you are also buying. If you have a king-size bed (like most of the UK) then you will need a kingsize mattress. However, each bed frame type may be slightly larger than the mattress depending on the design which you need to take into consideration.

Bed frame sizes dependant on style

The dimensions of your bed will vary depending on which style of bed frame or bed base you choose:

  • Divan beds should be the exact same dimensions as your mattress so they sit flush
  • Metal bedframes maybe up to 2cm wider to accommodate the mattress in the lip
  • Wooden bed frames are also a couple of centimetres bigger than your mattress around each side again sitting within the frame
  • Sleigh beds, upholstered bases, antique and custom made bed bases can have really different proportions and dimensions so always tripple check!

Always check metal, wooden, antique or custom bed bases as these can be upto 2cm bigger than your chosen mattress size.

Mattress bases drawer dimensions

People often ask how big are mattress drawers and the depths of them. It’s important to know what you could fit in them as mattress base drawers can offer hidden storage for smaller bedrooms. Here is a guide for our John Ryan Mattress bases.

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

We can make mattresses to a number of non-standard sizes. Especially if you have antique bed frames, require beds for yachts or any other bespoke mattress requirements. There is a price increase for bespoke work and it’s not covered by the love it or return it guarantee. Please get in touch for more details with us directly.

  • Ikea King  5’2″ x 6’6″ (160cm x 200cm)

European / Ikea sizes are usually slightly longer and wider than standard UK bed equivalents.  At present at John Ryan we don’t offer an Ikea Single equivalent as this is 6’6″ inches long where as a small single is 6’3″.  Our bespoke service can take orders of non-standard services such as this.

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!

Do you need a different size or shape altogether? If so then please get in touch and we can provide expert advice and guidance through our bespoke service. We have plenty of experience of making bespoke mattresses for antique bed frames, houseboats, caravans, motorhomes and other bespoke sleeping arrangements.
