Thank you for taking the time to leave us your feedback. As stated on the
4S0111 product page specifications tab, this 2 way draw sheet is only suitable for use on single, bariatric and queen size mattresses. We do however have a Pro4S extra wide 4 way draw sheet available (4S0108) which at 260cm wide is 60cm wider than the one you have purchased and may be more suitable for you? If you would like to try this item on your adjustable bed or return the sheet you have already purchased from us, please do email us at sales@nordiccare.co.uk so we can arrange this for you.
