First class service throughout from Happy Beds. Thank you very much. Mattress delivered earlier than expected. Delivery guys very friendly and professional. They found the marina very easy. I went to them after phone call, to say they had arrived. Helped me load mattress on a trolley, waved bye. Mattress looks great and fits perfect. Highly recommend Happy Beds.
