Box Springs

Shop box springs for supporting compatible mattresses and increasing the finished bed height. Select the same size as your mattress and choose between available standard and low-profile options.

Choose a box spring based on your mattress size, preferred bed height, bed-frame support and access into the bedroom. Compare standard, low-profile and split foundations before ordering.

Box Spring Buying Guide

Standard or Low-Profile Box Spring: Which Should I Choose?

A 7-inch standard box spring creates a more traditional finished bed height. It may be useful when you prefer a taller setup or have a lower bed frame.

A 5-inch low-profile box spring provides a similar foundation function while keeping the overall bed approximately two inches lower. It can be helpful with thicker mattresses, taller frames or when easier bed access is preferred.

The main difference is height—not necessarily support quality. Confirm the specifications of the individual model before ordering.

When Should I Choose a Split Box Spring?

A split box spring comes in two separate sections, making it easier to move through narrow stairways, hallways, elevators and bedroom doors.

It is especially useful for larger mattress sizes or homes with restricted access. Measure the entire delivery path before ordering, including door widths, stair turns, ceiling clearance and elevator dimensions.

Both sections must be placed evenly on a compatible frame with proper centre support.

Does Every Mattress Need a Box Spring?

No. Whether you need a box spring depends on the mattress and bed-frame setup.

A traditional open metal bed frame normally requires a compatible box spring or foundation beneath the mattress. A platform bed, adjustable base or properly supported slat system may allow direct mattress placement instead.

Always check the mattress warranty requirements and the support instructions for the selected bed frame.

What Size and Finished Bed Height Should I Check?

Select the same nominal size as your mattress, such as Twin, Twin XL, Double, Queen or King. Confirm the exact dimensions because sizing and split configurations can vary.

Calculate the finished bed height by combining:

  • Bed-frame or platform height
  • Box-spring height
  • Mattress thickness

A thicker mattress paired with a 7-inch box spring can create a noticeably taller setup. Consider ease of getting in and out of bed, headboard height and nearby furniture.

What Support Does a Box Spring Need Underneath?

A box spring must rest on a compatible frame or support structure. Wider Double, Queen and King setups generally require dependable centre support beneath the foundation.

Check that:

  • All frame rails are properly connected
  • Centre rails and support legs are installed where required
  • Every leg rests firmly on the floor
  • Both sections of a split foundation are evenly supported
  • The box spring matches the mattress and frame size

Do not place a box spring directly on an unsuitable or uneven frame.

Need a Custom Box Spring?

Standard box spring sizes and heights do not work for every bed frame or room. Sleepwell Bedding may be able to make a custom box spring or mattress foundation based on your required width, length and finished height.

Custom options can be useful for antique beds, non-standard frames, RVs, unique bedroom setups or situations where a lower or taller foundation is needed. When access is limited, our Winnipeg team can also review whether a split configuration would be suitable.

Provide the exact measurements, preferred height and details about the mattress and bed frame so we can recommend the appropriate foundation setup.
