Slatted vs. Non-Slatted Bed

Searching for a bed will take you down several paths, from divans to ottomans and low frames to poster frames. Another comparison is slatted versus non-slatted bases, which can affect the overall comfort of your mattress.

The bottom line is this -- slatted and solid bases have imperceptible differences. Thinner mattresses work better on slats because the extra flex of the slats reduces pressure on the mattress’s support system.

Any mattress over 20cm works fine on a non-slatted (solid) base, but a mattress thinner than this is best on a slatted base.

Ultimately, slatted bases suit a more comprehensive range of mattresses because they are suitable for all mattress thicknesses. Solid bases work fine with any mattresses over 20cm, so there is sufficient material between you and the base.

What is a slatted bed?

Slatted beds have a base with horizontal timber slats running across the width of the bed to support the mattress. Some slats are straight, while others have a subtle curve that lets them flex under load, creating a cushioning sensation.

Is a slatted bed base better?

Slatted beds are better when a mattress is under 20cm thick, in which case the flex of slats helps improve the mattress’s support system. However, slats can shift around and break, requiring more upkeep overall.

Slatted bed advantages

• Lighter
• Cheaper
• Better for thin mattresses

Slatted bed disadvantages

• Slats can break
• Slats can shift around
• Not always suitable for heavy people

Choose a slatted base if 

You want a standard or lightweight bed frame that is lightweight and suitable for all mattress thicknesses.

What is a non-slatted bed?

Non-slatted beds have a solid platform on which the mattress sits. The solid base adds height to the bed and is most common on divan and ottoman beds. The base is usually made from MDF and is covered by the same upholstery as the frame.

Is a non-slatted bed base better?

Non-slatted bases are more consistent than slats because they don’t move and never break, making them a better choice if you value longevity. However, a solid base can make some mattresses feel firmer than they are.

Non-slatted bed advantages

• A base will never break
• Cheaper
• Better for heavier people

Non-slatted bed disadvantages

• Heavy
• It can make mattresses feel firmer.
• More expensive (on average)

Choose a non-slatted base if

You are heavy, want a bed base that will never shift or break, or benefit from a firmer feel to your mattress.

Does the base of a bed make a difference?

The difference between a slatted and non-slatted base is subtle and, in many cases, imperceptible when a mattress is over 25cm thick.

However, solid bases can make softer mattresses feel firmer, while slatted bases retain the original feel of the mattress. Slatted bases are better for softer and thinner mattresses, while solid bases are better for firmer mattresses and heavy people.

In short, the base of a bed does make a difference sometimes; if you have a soft mattress, it is best to get a slatted base to preserve the plushness. If you are still unsure, it is worth trying both types of bed bases with the same mattress firmness as your own.

How long does a bed base last?

The answer depends on how well you treat your bed! Solid bases last longer than slats in most scenarios because slats are easier to break. However, if you look after your bed, both slatted and solid bases will last a decade.

How important is a good bed base?

A bed base’s importance comes second only to the quality of your mattress. A good base will preserve the original feel of your mattress while ensuring the support system does its job. If you have ever slept on a mattress on the floor, you will know that a solid platform is not always best when a mattress is soft or thin.
