The backrest on the RH Logic 300 has been designed with extra support in the mid back and is tapered towards its top to enable free movement of the arms. The seat includes a layer of wool, providing improved ventilation and making it cooler than conventional pads. Its waterfall edge has been designed to reduce pressure on the underside of the thighs with the aim of promoting circulation. To maximise the life of the chairs the seat and back pads are modular and can be exchanged without having to replace the whole chair.

We understand that there are a large range of options available for the chair and so why not take us up on a free telephone consultation where an ergonomics consultant will take you through all the options available. You can contact us by calling 0203 051 0157 or email info@fluto.co.uk.

The range explained

There are 4 main chairs in the RH logic range: the RH Logic 300 and 400, and the Logic 4 and Logic 3. It is worth noting that the 400 is more suitable for individuals over 5ft 6. Any users under 5ft 6 please see the RH 300. All the chairs have almost identical functionality but there are some small differences worth noting. The Logic 4 and 3 have their levers on the underside of the seat, whilst the 400 and 300 have easily accessible buttons on the side. It's easy to replace the pads on the 400 and 300 (snap function) but more difficult on the 4 and 3 (the chair has to go back to our warehouse). Finally, the seat on the 300 and 400 has a layer of wool, providing extra ventilation.Within the range you can also get the Elegance version of each chair. The only difference between the Elegance and the standard versions is that the Elegance comes with an upholstered back as standard. You can select the upholstered version from the drop down options. If you are still not sure about the model that you need please contact us.

What we like/what customers like

Alongside the 400, the RH Logic 300 is our most popular remedial ergonomic chair in the UK. The low back has made the chair particularly popular for shorter clients.

I was recently referred to a physio physio who recommended the 300. I wasn’t sure what to expect but I have been pleasantly surprised with the comfort of the chair. I tend to slouch and I have found the inflatable lumbar support particularly helpful.

David Peter, Kent

Great chair, very comfortable – the only negative is the tension adjustment that needs to be turned a lot to make any real difference to the rocking tension.

Lindsey Bell

Love it!!!

Wendy Carwright

I work as an IT consultant and after years of chair perching I developed a nagging low back pain. I was recommended the chair by my physio. I wasn’t sure to start with whether it would be worth the investment but I have to say have been really impressed with the chair. It took some time to learn the levers but now I am comfortable adjusting the chair on my own. I tend to lock the chair for typing but leave it unlocked for when I am in a meeting or on the phone.. great buy........

I have had neck pain for the last 5 years and have never found a chair that is comfortable. The chair felt strange at first and I got some new aches and pain but over the next week they just disappeared. I still have the neck pain but I have noticed that I can sit much more comfortably and as a result I am more productive and less grumpy with my colleagues!

The rh 300 is in a league of its own. I love it but Just don’t tell your colleagues or they will steal lit. Great, fast service - thanks Fluto.
