Boat Mattresses – Reasons to ditch springs

Replacement boat mattresses can be difficult, especially those that are custom built making them even harder to source. Over the last decade we’ve become mattress specialists in our field. Through our foam advanced foam technology we have achieved greatness and are able to provide you the best quality memory foam mattresses for boats you’ll ever lay on. Traditional spring mattresses can lose up to 16% of their support within their first year, offering very poor value for money in comparison to memory foam. In general, the benefits of a memory foam boat mattress far outweigh that of traditional sprung mattresses. The benefits alone of no motion transfer and no partner roll-together is the perfect combination to help you get the best night’s sleep you deserve. A key point to note is that building odd size mattresses with springs becomes a little more problematic, as the size of your mattress has to be made in increments based on the size of the spring. Memory foam mattresses don’t have this issue, therefore resulting in a cheaper price.
