So that we can safely and efficiently deliver your bed or mattress, it’s important to ensure that your new purchase will fit through your home to get to your room of choice. If you’re wondering how to choose a bed and what needs to be considered, then we’ve got you covered. Below are the key measurements that need to be taken, using a tape measure and optionally a protractor or angle finder, before making your purchase:

measure your room

measure your room

First of all, make sure the new mattress physically fits in your bedroom. But also consider any furniture and space to move around the bed. Consider the bed base, while divans are usually the same width and length as the mattress plus headboard, many bed frames are slightly wider and longer. Check all the sizes before you order.

measure your doorways

measure your doorways

Most mattresses shouldn’t be bent, so measure your front door, and any doorways between the front door and the mattresses final space. The doorway should be higher than the mattress width. If measuring diagonally, be sure to account for the mattress depth also.

measure your stairway

measure your stairway

Often the tightest point is the staircase. Measure the distance to any low ceilings perpendicular (at a 90° angle) to the staircase. The clearance should be comfortably greater than the mattress width to ensure a good fit without scuffing anything. While you’re measuring for height, Watch out for lamp shades too!

measure any corners

measure any corners

Consider any turns that your mattress will have to make. That could be a turn in the stairs, or in a hallway - often around the banister rail too. Measure against the mattress length and depth to ensure your mattress can make it round without being bent. Pro Tip: if the mattress will fit across the corner at 45°, it’ll turn all the way around just fine. This is also a good opportunity to remove any hanging pictures, mirrors etc.
