I was hesitant to order an adjustable bed on line without seeing it in a store.  I needed a king but you were out of stock.  I took a suggestion from a review and ordered (2) Twin XL to put together to make a king.  It worked out great.  The base was so easy to put together and is very quite as noted in previous reviews.  I have slept on it for 2 nights now and LOVE it!
