Constructing a DIY memory foam mattress requires a high resiliency foam (known as HR foam) with a density rating of 2.5 – 3lb/ft³ with an indentation load deflection of 26lbs or 31lbs according to Healthy Foundations, a memory foam specialist.

You can follow the materials formula and resources under the cut to create your own budget Tempur-pedic memory foam mattress…

The Nobot made his own memory foam mattress using the following materials from wholesale memory foam dealers:
From top to the bottom layer:

  • $95 MF4Q62 Memory Foam 4.3LB – Queen – 60″x80″x 2″

  • $182 MF5Q63 Memory Foam 5.3LB – Queen – 60″x80″x 3″

  • $34 LRFE82 Lux Regular Foam – Eggcrate – 82″x76″x 2-1/2″

  • $114 LHQFFS84 Lux High Qual. Foam – Full Sheet – 82″x76″x 4″

Total price, shipped, was less than $450.

As you can see, memory foam density is a highly subjective choice, as some may prefer a higher density, while another may prefer a cushier ride. Your best bet is to contact a foam dealer for small square samples to get an idea of each density rating and create a mattress accordingly. And if you don’t like it, you can always use the memory foam for other projects.

*we’d like to note we dropped by our local Target and noticed starting Monday all the way through Saturday, Target is having a sale on all their memory foam products.
