The most popular overlay in our range, this convoluted "egg carton" overlay / topper is made from soft, strong premium quality H28-80 foam. This overlay / topper is thicker than most of its competition, with a 60/30mm convoluted profile. It will add comfort to most any mattress, and especially relieves aches and pains caused by hard sleeping surfaces. In our opinion this is one of, if not the best foam overlay available, and is great value for money too. No wonder we sell so many! Note also that this quality foam overlay will extend the service life of your mattress by many years. Inner-spring mattresses have a top layer of foam that flattens with use over time. By doing the work of this foam layer Foam Sales' overlay will significantly extend your mattress' service life. For more information on this overlay, and on the features and uses for foam toppers in general, visit our information page.

We recommend replacement after 4-5 years for ageing and hygiene reasons. For these same reasons we do not accept returns on convoluted overlays that have been used.

Overlays, wedges, and new mattresses all can be left in the open to air for a day or two if the new foam smell is noticeable, or likely to cause irritation.
