To enhance the beauty of a sturdy pergola model, we would advise that furniture provides a contrast in style, colours or materials. For example, you may choose a basket or rattan finish for chairs and beds rather than more metal. This will provide interest and variety.
There are plenty of deals available for furniture purchase, particularly in an end of season sale, and you may well find that you can get a discount off your first order or pay over a longer period. Lots of companies in the UK will deliver your furniture for free and offer additional services if you are eligible, some may also assemble your items for you.
