Pull out beds are convenient, space-saving, and versatile – but choosing the perfect mattress for one can be a challenge. As a mattress reviewer, I\u0027ve tested hundreds of mattresses and analysed the key features that make a mattress suitable for a pull out bed. In this comprehensive guide, I\u0027ll walk you through the factors you need to consider, the top mattress types for pull out beds, and how to find the best fit for your needs and preferences. So let\u0027s dive in and find the perfect mattress for your pull out bed. Pull out beds come in various designs and mechanisms, including: Sofa beds: A sofa that converts into a bed, with the cushions removed and a fold-out mattress. Futons: A low-set frame that can be converted from a sofa into a bed by unfolding the mattress. Trundle beds: A bed that slides out from underneath another bed, typically on casters. Daybeds: A bed that functions as both a sofa and a bed, with a standard mattress. We’ll only be looking at mattresses to suit trundle beds and day beds for the purpose of this exercise and the other options will generally come with a mattress built-in or on delivery. Factors to Consider When Choosing a Mattress for a Pull Out Bed To choose the best mattress for your pull out bed, consider these factors: Comfort: The mattress should provide a comfortable sleeping surface that contours to your body and relieves pressure points. Support: A good mattress should offer adequate support to maintain spinal alignment and prevent sagging. Durability: Look for a mattress that can withstand repeated folding and unfolding without losing its shape or comfort. Ease of use: The mattress should be easy to fold and unfold, without being too heavy or cumbersome. Breathability: A breathable mattress helps regulate temperature, ensuring a cool and comfortable sleep. Budget: Determine your budget beforehand and look for a mattress that provides the best value for money. The Top 3 Mattress Types for Pull Out Beds When it comes to pull out bed mattresses, three types stand out: Memory foam: Memory foam mattresses conform to your body shape, providing pressure relief and support. They\u0027re lightweight, making them easy to handle and fold. However, they can retain heat, so look for one with cooling features. Open Coil: Open coil mattresses offer a traditional feel and good support, thanks to their coil system. They\u0027re more breathable than memory foam but can be heavier and less flexible, making them less suitable for some pull out bed mechanisms. Hybrid: Hybrid mattresses combine the best of both worlds – the support of innerspring coils and the contouring comfort of memory foam or latex. They\u0027re suitable for pull out beds that can accommodate a thicker mattress. Pull out bed mattresses typically range from 4 to 6 inches in thickness with a thinner mattress being easier to slide away and store, but may compromise on comfort and support. Consider the bed\u0027s mechanism and storage space when choosing the thickness and go for the deepest you can afford as a general rule of thumb (although there are numerous exceptions).
