Service Rating : Responded quickly to my email enquiries. Fast delivery for Covid era.

Product : Seat cushion no good for sitting up in bed - just too hard for me. I had emailed and asked specifically if it would be ok for this situation and told it was suitable, but not at all. If I can get to sit out in a chair I will try it then .

Service Rating : the item arrived within 48 hours.

Product : I have a top of the range mobility scooter parts nevertheless these suspension did not cope with uneven paving. I did not find a suitable caution on mobility scooter websites and by chance turned to wheelchair were I located this caution. Obviously one would prefer our testing the product before purchase but the price seem to be reasonable and the result has reduced the jarring of my vertebrae by approximately 80%.
