A sturdy support which works well. It is advertised as being good for travel but comes with many dire warnings that it must be used with the anchoring strap to avoid entrapment. This is impossible with a double bed or heavy mattress especially if the user is disabled and travelling alone. I used it without the strap in a double bed and it worked brilliantly. I intend taking it to South Africa next year. The warnings should be restricted to those who are vulnerable to the risks of entrapment. I was nearly put off by them but was very pleased that I "broke the rules"!
