How to choose an adjustable bed rail

An adjustable bed rail can reduce the risk of falling out of bed while you sleep, provided it’s suitable for the bed, mattress and person using it. Whether you’re moving a child into a bigger bed, caring for someone who is vulnerable, or sharing a family bed, your choice shouldn’t be based on colour or price alone.

There are a few common pitfalls to watch out for when buying.

Common mistakes to avoid before you buy

• Confusing adjustable height with adequate protection: a 50 cm rail won’t necessarily suit every mattress. With a deep mattress, the part that actually extends above the sleeping surface may be too low.
• Overlooking the fixing system: a bed rail must be held securely between the mattress and bed base, or fitted in accordance with the manufacturer’s instructions. A poorly installed rail can move as soon as a child or adult leans against it.
• Choosing the wrong length: a rail that’s too short will only cover part of the area you need to protect. On a large bed, two 50 cm sections may be more practical than one.
• Relying on marketing claims alone: terms such as ‘safety’, ‘fall prevention’ or ‘family’ are no substitute for checking the dimensions, materials, weight limit and instructions for use.

A fall-prevention bed rail is never a substitute for appropriate supervision. Don’t use one if it leaves a dangerous gap between the mattress, bed frame and rail.

What to check before you order

1. The height that actually extends above the mattress

Compare the stated height with the combined thickness of your mattress and mattress topper. A 50 cm bed rail may suit a relatively low sleeping surface, while a 60 cm bed rail will extend further above a deep mattress.

Height isn’t the only thing to consider. Also check:

• the minimum and maximum heights;
• how many positions are available;
• whether there’s a locking mechanism;
• the gaps between the different sections and the mattress.

A model with 5 adjustment holes will usually offer a choice of heights. Even so, check the product listing and instructions for the exact dimensions of each position.

2. Whether it’s compatible with your bed

Measure the length of the area you need to protect, as well as the mattress thickness and bed base structure. Beds with drawers or storage compartments, along with beds with very thick frames, may not leave enough room to fit the rail properly.

For a child’s bed rail, check in particular:

• that the bed base is stable;
• that there’s no gap between the rail and the mattress;
• that you can fit and remove the rail without forcing it;
• that it’s compatible with a single, double or family bed.

To protect a family bed, two 50 cm sections can cover a wider area or protect both sides of the bed. However, you’ll need to check the joins and ends carefully.

3. Documents and precautions for use

Before placing your order, look for clear instructions, contact details for the manufacturer or seller, full dimensions, and any age or weight limits. CE marking, where applicable, is no substitute for reading the instructions and checking that the rail is fitted correctly.

Once assembled, apply moderate pressure to the rail. Check that it doesn’t lift or tip, and that it doesn’t leave a gap between the rail and the mattress. Inspect the screws, straps, joints and adjustment parts regularly.

Frequently asked questions about adjustable bed rails

How do you fit a fall-prevention bed rail?

Fit it in accordance with the instructions, check that the parts are facing the right way and make sure it’s held securely by the bed base or the specified fixing system. The mattress should sit flush against the rail, with no accessible gap. Then check that the rail is stable along its full length.

Is a 50 cm bed rail suitable for a child?

It depends on the mattress thickness, the height of the bed and the child’s age. Measure how far the rail actually extends above the mattress. Follow the manufacturer’s usage limits, and never treat the rail as a substitute for supervision.

When should you replace a child’s bed rail?

Replace it if any part is cracked, a fixing no longer locks properly, the fabric is torn or the frame feels loose. Regular checks are particularly important after taking the rail apart, moving house or using it frequently.
