Hi Erica,

Thanks for getting in touch and we're sorry to hear you're having such bad luck with your Harrisons mattresses. This is really unfortunate as Harrisons are one of the better mattress manufacturers here in the UK and they are well respected.

In terms of your first mattress, given Harrisons accepted there was a fault then we won't go into details about this model, However, its important to discuss guarantee vs warranty with mattresses. This is where most customers get a bit lost. It's an incredibly important detail when choosing a new bed or mattress.

A bed guarantee will cover the mattress from defects and failures for the term of that guarantee. Ie 5 years means that if a fault develops and is assessed by a furniture inspector then the company will usually either repair or replace. That's the guarantee that we apply to all of our models.

A warranty, however, is different. Most warranties are proportional which means that after a certain time usually 1-2 years you then only get back a proportion of the original cost of the mattress. Even if it develops a fault as you're deemed to have 'used a portion of the bed' before the fault. We think this is rather unfair to consumers.

We never use warranties only guarantees. You can read more on the different brands guarantee terms and conditions in this detailed article here.

Natures Finest Pillowtop 8500 DNair Mattress Review:

Let's have a look at the replacement mattress and why it too may be failing or showing signs of an issue. The first thing Erica is its a pillow top mattress construction method. Meaning you can only use one side of the mattress. You can't turn it to even out natural settlement. You also can't remove the pillow top topper. So when this compresses and sags that's it. It's game over. We've long battled for other brands to avoid this mattress construction technique.

This mattress also uses micro springs, which again we refuse to use. This is because in our tests they serve very little purpose in terms of support. More to increase the spring counts from a marketing perspective in retail. They also reduce the space for more supportive upholstery which is why we choose to avoid them. We prefer a quality full-size pocket spring unit and then copious amounts of fibres which act as secondary support and then a comfort layer for your bed.
Whilst this mattress features natural fibres, they are all contained in this pillowtop layer. The main mattress itself from Dreams cutaway on their website shows its 100% synthetic. It's a shame that this model doesn't remove the pillowtop and then split the fibres onto each side of the pocket spring unit. That way it could be turned each month and avoid early sagging or compression which it sounds like you are experiencing.

Natural fibres will keep you cooler at night and although Latex is natural it is still far more heat retentive than other fibres. We would advise you have a look at our Artisan Naturals mattress as a comparative model that will give a medium feel to you but is 2 sided and far more breathable. It contains a high end spring unit (calico encased pocket spring) and zero micro springs. You should always be aiming for a two-sided model where possible. Even if you struggle to turn it, getting a friend to help at least means you have two sides of your bed to play with avoiding the issues you've experienced with the last two mattresses.
