The no turn mattress scam

So you’re searching for your new mattress and you see an icon with ‘No turn mattress’ and think brilliant that will save me some effort! But let’s dig a little deeper behind this ‘benefit’ and explain why it’s not in your interests to choose a no turn mattress over a two-sided model.

With the influx of one-sided boxed mattresses such as Eve, Casper and any Pillowtop mattress you may be fooled into thinking this is a time-saving benefit. A one-sided mattress can’t be turned so surely that makes mattress maintenance far easier? We explain why you need to carefully consider whether you’re ready for the potential drawbacks of a one-sided mattress.

What is a One-sided mattress?

A no-turn mattress is not a benefit, but a necessary requirement for most memory foam and foam based beds. Don’t be fooled into thinking it’s a feature it’s simply one of the drawbacks of these mattresses. We have written previously about the one-sided mattress problem which should be read in conjunction with this article.

A one-sided mattress has fillings such as foam or high loft fibres in the top layer of the mattress. These can’t be turned over because if they were, they would get crushed and potentially not return to their usual shape or feel.

Why is it no turn?

These ‘No turn’ or one-sided mattresses are made using the principle of a firmer base layer being layered with softer layers on top. So you start with the firmest and work your way up getting softer the higher up the mattress. If you imagine the memory foam or latex top layer as the softer mouldable layer of the bed with the firmer reflex layer as the base.

The Pillowtop is one of the worst construction methods of one sided no turn mattresses

If you also had a soft memory foam layer under the base say to make it two-sided, it would become compressed very quickly as the entire weight of the sleeper and mattress would be pressing down on it. It would be crushed over time and become useless. This is why these mattress types are always no turn.

The sales pitch makes you think this will save you effort but actually not turning or rotating your mattress will simply reduce its lifespan dramatically.

There is also an argument that No-turn mattresses allow manufacturers to reduce the amount of upholstery fillings in their mattresses. As they are only upholstering one side. It also means that in cheaper mattresses larger cruder spring units and large sectiosn of foam can be used to bulk up the base of the mattress.

But shouldn’t I turn my mattress to extend its lifetime?

Yes, you should, but the construction of memory foam means this is somewhat impossible. You can rotate the mattress to even out wear. You can’t turn it or you would be sleeping on the firm reflex layer which would give a completely different feel to the mattress and damage the top layer as the weight shifts onto it.

All mattresses should, at least, be rotated 180 degrees, if they can’t be turned over, once a month to help even out wear. If not the mattress will settle far quicker leaving potential dips and sags.

All of our Artisan Mattresses are two-sided and fully turnable

Doesn’t this mean my mattress is of a lower quality to a traditional mattress?

Not necessarily it is just a different construction method, what we are doing is giving you awareness not to consider a no turn mattress as a benefit or deal maker when out looking at mattresses. Foam mattresses can have many benefits, such as allowing progressive comfort with their layering, but the drawback is that it is always going to be a one-sided mattress.

It must be said that a one sided mattress if only rotated will naturally have a shorter lifespan than a two sided fully turnable mattress

What’s the solution to no turn mattresses?

We acknowledge the drawback of no turn mattresses and our unique design of mattresses gives you the possibility of a partial turn mattress with our hybrid foam mattresses for this reason. Buying a mattress is usually a significant expenditure if you’ve done your research and are truly buying a fit for purpose mattress.

Adding a deep topper can help reduce the issues with one-sided mattresses

Adding a deep two sided topper can help reduce the issues with one sided mattresses

All of our hybrid and latex mattresses come with our dual construction method, not seen in many of the retailers. This constructs of a high-quality memory /hybrid foam base with a matching high-quality topper. This means that you can rotate and turn the topper when you normally would turn your mattress.

The easiest way to remove the drawbacks of a no turn mattress, however, is to buy a two-sided well upholstered mattress.

    I came across your interesting website today and hoped to ask for some advice please…I only wish I had found you earlier!


    I purchased a FRESH 1800 6ft mattress from M&S last year, and within 6 months it was badly sagging.
    My partner and I are only 9 and 11stone, so thats not an issue.

    The mattress sits on top of a 6” sprung base – the format that folds in the middle. Its a traditional cast iron frame and a well made bed.

    M&S instructed an independent company to assess it, who confirmed a 5” sag in the bed, however they are entirely blaming the sprung base on the reason for the collapse.

    They suggested I should replace the sprung base with solid wood, screwed into the metal frame. Insane comments I think!

    I have issues with the delivery method as the 2 men carrying it up into my top floor room really struggled with the weight and size, bending and forcing it up the stairs. Would you have any recommendations on this aspect?

    I have had a 6 month ongoing dispute with M&S and they are now willing to replace the mattress with a very similar model – the comfort 1800.

    I am keen to know if you are aware of similar issues with either mattresses and your opinion of them both?

    Also if you have an opinion on the sprung base I bought with the original bed? What is the ideal format to use on a bed that doesn’t have slats?

    What would you recommend overall?

    much appreciated

    Hi Aileen, Thanks for getting in touch. It does sound very unusual that theres a 5” sag, that to me would only happen if the spring unit has failed. Obviously I haven’t seen the mattress so thats as far as my comment can go and can’t really comment on your base either. I can however empathise with your frustration.

    What I can do is give the advice we give to customers everyday so you can assess for yourself. When customers ask us about using their existing bases we always advise that as long as the existing base is sound, that any spring units are still in tact i.e. not poking through or sagging, and that any slatted bases are no more than 2cm between slats, the base should be fine. The primary thing with a base is a consistent surface; whether sprung or platform top. It is when the base sags, dips or has broken springs that this can damage and effect the performance of the mattress.

    A quality mattress should be able to flex and move to accommodate manoeuvring it to a room of your choice. I wouldn’t say with the limited information its necessarily this thats caused or contributed to the issue.

    We would need some more detail to be able to recommend one of our mattresses for you Aileen in which I’d ask you to call us directly. I wouldn’t comment on the mattress you have referenced other to say its a one sided mattress meaning it doesn’t compare to a two sided quality pocket sprung unit as you only ever have one side to work with. There are not enough details to make a true comparison for you I’m afraid. You only have a one sided mattress by necessity i.e. a latex or foam topped mattress. We don’t sell any one sided fully traditional mattresses of this sort. I hope the advice is of some use to you and wish you well in resolving your dispute with M&S. – Lee
