Key Takeaways

Trundle bed mattresses are typically thinner than normal ones since there is only space for the trundle bed and mattress under the parent bed.

The standard mattress thickness for trundle beds ranges between 6 and 8 inches in depth.

If you do not want to use a trundle bed there are alternative support bases for your mattress, including these 5:

There are also similar setups to a trundle bed, like the daybed. A daybed is a 3-sided design often combined with a twin mattress.

If you do not want to use a trundle bed there are alternative support bases for your mattress, including these 7:

• Adjustable bed: Incredible for blood flow and overall pressure point relief. (our favorite adjustable bed is the saatva-lineal).
• Platform bed: Great firm bed base. A lot of aesthetic variety and customizable.
• Normal bed frame: Simple and minimalist. Good sturdy support.
• Box spring: Traditional. Comes in low profile and standard. 4-8". Great overall support.

What About A Trundle Bed With A Daybed?

A daybed with a trundle is a sofa-bed hybrid. It is very versatile and can be decorated to look like a couch. Daybeds and trundle beds have the following characteristics which you can consider if purchasing one:

• The height of the daybed mattress varies from 8 to 10 inches, and the height of the trundle bed mattress underneath may vary between 6 to 8 inches.
• Daybeds are a great solution for people working from home because they provide a place for sleeping and sitting during the day. They can also be used in kid rooms to save space.
• Daybeds do not come in a queen or king size. However, you can use a pop-up trundle bed to provide a large sleeping space by joining the daybed and the pop-up bed at one edge.

Other Trundle Bed Faqs And Considerations

Take these 4 major FAQs into consideration when deciding to purchase a trundle bed:

1. Length and width limitations of trundle bed mattresses:

• The length and width of trundle beds are usually smaller than the parent bed.
• Some materials such as memory foam can expand less than their full size and hence fit trundle bed frames as well as normal bed frames.

• To feel comfortable, consider the area where you want to place the bed.
• Yourself and the other person occupying the bedroom.
