Arrange help without losing your own say
A relative can take notes or help compare quotations, while your comfort remains the priority. Try sitting, using the controls and getting up at the landing. Explain what you would need to do when that relative is not there.
Try the everyday movements
Ask about sitting down, positioning your feet, fastening the belt, using the controls and turning at the landing. Check the proposed manual or powered features in a demonstration. A feature list is less useful than understanding how you would use the chair yourself.
Check the Acorn proposal in detail
Ask Acorn to list the chair model, rail route, installation, warranty, servicing, call-outs and optional extras in your written quotation. Confirm the contracting Acorn entity and the teams responsible for installation and repairs. Keep the written answers with your project documents.
Take time before agreeing
Check deposit, cancellation, bespoke-work, removal and complaint terms in Acorn's documents. Ask a qualified adviser about any support or funding relevant to you; this site does not determine eligibility. Do not assume an advertised discount or grant is a price you will receive.
