If you want rattan chaise lounges which will last a long time, you should be prepared to pay between $500-$800 per item. There are cheaper variations available, but they will generally last 1-2 years rather than up to 10 years. When deciding how much to pay for furniture, one of the essential factors to consider is how long you intend to keep the furniture for.
Many items also come with a warranty, so if you find that there is a manufacturer's fault with the furniture, you can get a replacement free of charge. Depending on the warranty package which comes with your furniture, you might also be able to get compensation or replacements for accidental damage. If you want extra cover, you can always take out a separate insurance package when purchasing.
