I have been using a Drive Nitro for the past 3 or so years, I have other walkers but the Drive is far the best, it has the ability to fold up to enable you to get through smaller gaps, it has a seat and a folding basket. However it best feature when you are travelling across uneven ground the frame flex’s (i.e it does not 3 wheel) making it very stable.
You can buy them on the site which begins with an E, I brought my through Lloyds Pharmacy, I paid about £125, I think they are about £150 now, they do accessories for your walking stick and drinks bottle if needed.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
