  • Review for Relyon Original Memory Foam Mattress with Coolmax Cover

    Superb product and service

    Bought a mattress from a local bed shop,at a much dearer price had it a month before giving it to a charity. Cannot believe the comfort and quality of the Relyon mattress,the speed it was delivered and the service I received from the lady I spoke to.

  • Review for Shire eco SOUND Mattress

    Excellent mattress very pleased

    I bought this with some reluctance simply because it was online and I had not seen it or tried it out. But I need not have worried. This is a superb mattress to sleep on and the quality is excellent. I can see what the original price was over £700 for the single and chuffed to bits I got it in the sale for over half price - bargain!

  • Review for Sleepsnug Refresh 1500 Mattress

    Very Comfortable

    I find this mattress nice and firm at first, with a firm supportive base. As the foam warms a little it becomes softer to give just enough give to relieve pressure without becoming a soft mattress.

  • Review for Sleepsnug Backcare Mattress

    Does what it says on the tin

    They said delivery on Friday, and it arrived on Friday.
    It is 20cm deep, and medium to firm which is a blessing for my slipped disc. I let it stand for most of the first day to ease some of the manufacturing smell. I wish I'd bought this straight after getting rid of my last orthopaedic mattress for my divan instead of a memory foam one. Trying to turn over in bed with a bad back on a memory foam mattress is a big problem, but not with this. £140 very well spent.

    Brilliant service

    The service I got through buying this mattress online was very good. I was a bit hesitant at first about buying it online just incase it wasn't what I thought and could not do with the hassle of sending it back but the mattress is super comfy and I'm very happy with it - awesome price too!

    Absolutely perfect mattress

    This mattress is absolutely sublime, I had heard of Hypnos before as being a luxury mattress brand and I have not been disappointed at all. My husband and I have slept exceedingly well on it and I think it is more than worth spending a little more for a superb night's sleep. The quick delivery also made the entire process very simple and pleasing.

More on 4ft 6' Mattresses

A double mattress is the most popular mattress size you can find on the market and it is specifically designed to provide space for two people to comfortably sleep on.

 

When choosing a new mattress, bear in mind that mattress sizes in the UK remain the same whichever manufacturer makes the mattress. This is sometimes not the case for divans and besteads but always the case for mattresses. The industry standard for a double mattress is 135cm x 190cm, which is 4' 6" by 6' 3". European and North American sizes for double mattresses can differ so be aware of this if you have imported your bed.

 

While mattress sizes are standardised in the UK bed industry, the depth of a double mattress will depend on the structure and the fillings within the mattress. Nevertheless you can assume that all 4ft6 mattresses are generally between 15cm and 30cm deep which is reflected by our selection of double mattresses for you here at Only Mattresses.

 

Airsprung, Relyon, Joseph International or Healthbeds - whichever brand you choose, nearly all their mattresses will be available in a double and you can choose from a variety of comfort levels, firmnesses, fillings, finishes and types. Including pocket sprung, memory foam and latex.
