Custom 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 providing you with 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.

With our custom boat mattresses, be rest assured that every night spent aboard your boat mattress is a restful one, allowing you to make the most of your cruise.

We know it isn’t easy to install a replacement mattress in a boat which is why we vacuum pack and roll all completed mattress prior to dispatch. Not only does this prevent your mattress getting damaged in transit, but it also makes installation incredibly easy. Carry the compact roll through the narrow door and round the corner and lay it on the bed frame. Now carefully cut the plastic bag open and watch the mattress unroll and expand into position! Leave the mattress in place for around 5-6 hours and your ready to spend your first night on your new boat mattress – If only everything was this easy!
