I was looking for an affordable mattress that would work on an adjustable bed. This is the only 'economy' foam mattress that actually stated in the description it could be used on adjustable platforms-you need to get the XL. It works like a charm! It is not quite as soft as I expected and takes a few night's sleep to realize your body really is being nicely supported in all the right places. Well packaged, arrived quickly, expanded to full size quickly and the 'new foam' smell did not linger for long. I'm very happy with the purchase.
