Things to consider before buying a narrow twin cot mattress

There are many mattresses and cots on the market that provide different features and functionalities. Each style has a different function and therefore should be used for different situations. Before purchasing you need to analyze a few important factors. 

  • Mattress Quality – How high quality does the mattress need to be? Will this be a place that a child is sleeping on for one night or an adult friend for a week? Trifolding mattresses tend to be the highest quality sleeping surface but will be the most expensive, while a cot may be affordable and easy to move but doesn’t offer much in terms of long term comfort. 
  • Bed Size – Is your cot on sleeping platform a standard narrow twin or cot size? In recent years there are some cots that come in different sizes so make sure to measure your platform and get a mattress that fits. Generally around 1 inch of variance is expected and will still fit. 
  • Storage Size – What size room will this bed be in and how much room is available for storage. The amount of room that a murphy bed and a cot bed take up is very different so be sure you know the amount of storage space you have available. 
  • Frame Type – From metal frames to no frame at all, these beds all have a different type of frame that they utilize. While you can put your mattress on the floor, a rollaway bed sits off the ground and has a metal base with wheels. Understand your needs and choose a bed frame that is right for you. 
  • Weight – Will you be carrying or traveling with the bed? How easy does it need to be to move? We have listed a variety of beds from light to heavy below so be sure to choose one that fits your needs when it comes to portability. 
  • Price – How much are you wanting to spend? Options below range from $25 to $2000. While you generally do get what you pay for when it comes to quality sometimes you may not need the fanciest sleeping accommodation if it is only used on rare occasions. 

Overall, which cot mattress you choose really depends on your specific sleeping needs.

The variety of manufacturers and options on the market today allows you to find a solution that is perfect for all needs.
