A sofa bed is one of the most useful pieces of furniture you can own, saving space while giving guests somewhere to sleep. The catch is comfort. To fold away, the mattress has to be thin, the frame can have a bar or seam you feel through it, and gaps around the edges leave the surface uneven. None of that means you are stuck with a bad night’s sleep.
The good news is that most of these problems are easy and inexpensive to fix. With the right topper, a little support, proper bedding and a few quick adjustments, almost any sleeper sofa can feel far closer to a real bed. Work through the steps below roughly in order, since the first few solve the majority of complaints on their own.
1. Understand Why a Sofa Bed Feels Uncomfortable
Understanding the cause of discomfort makes it much easier to fix. Most issues come from design compromises rather than defects, and each one has a straightforward solution.
Common culprits
- Thin mattress: Sofa beds use thinner mattresses so you often feel the base underneath.
- Support bar: On pull-out models, a metal bar can press into your back or hips.
- Gaps and uneven areas: Gaps between sections can create lumps or an uneven surface. Squeaks and movement of loose parts or wear can cause noise during use.
- No headboard: Without support, pillows slip and sitting up feels uncomfortable.
2. Add a Mattress Topper (the Single Biggest Upgrade)
If you make only one change, add a mattress topper. It is the fastest way to improve comfort and reduce pressure from bars or springs, turning a thin sofa bed into a much more supportive surface.
Choosing the right topper
- Material: Memory foam or latex contour to the body and ease pressure on hips and shoulders, while foam or fibre options add basic softness at a lower cost.
- Thickness: Aim for at least 5 cm (2 inches). Thicker feels more comfortable but is harder to store.
- Sizing: Match the topper to the fully opened bed so the surface stays flat and even.
- Storage: Most sofa beds cannot be folded with the topper on, so you will need a place to store it when not in use.

3. Support the Mattress from Below
If you can feel bars or slats through the mattress, adding a support layer underneath is one of the most effective ways to improve comfort and reduce back pain on older sofa beds.
Ways to add support
- Board or panel: A thin plywood sheet or bunkie board placed under the mattress helps distribute weight and reduce pressure from metal bars or gaps.
- Extra foam layer: A simple foam pad adds cushioning between the mattress and frame, reducing hard spots.
- Check the base: On click-clack or futon-style beds, ensure the support panel is properly aligned and not sagging before adding extra layers.
Tip: Keep any board slightly smaller than the mattress so the bed still folds, and round or tape over sharp edges.
4. Fill the Gaps and Even Out the Surface
Gaps around a sofa bed mattress can affect comfort and create spaces where small items slip through. Filling them helps create a flatter, more bed-like surface.
Quick gap fixes
- Rolled Towels or Foam Strips: Place them along the edges to fill gaps between the mattress and frame.
- Pool Noodle Trick: A foam pool noodle tucked under the fitted sheet along the edges creates a soft bumper and smoother surface.
- Smooth the Seam: A mattress topper helps bridge the joint on click-clack beds, reducing the feeling of the central crease.
Tip: A deep fitted sheet pulled tight holds your gap fillers in place and stops everything from shifting overnight.
5. Layer the Bedding Hotel-Style
Good bedding does more than improve appearance. It adds softness, warmth, and makes a sofa bed feel like a real sleeping space rather than a temporary setup.
How to layer
- Start with a Protector: A mattress protector keeps the built-in mattress clean and adds a light comfort layer.
- Use a Well-Fitted Sheet: A fitted sheet sized to the open mattress helps keep the surface smooth and in place.
- Build Layers: Add a flat sheet, duvet, and an extra blanket for warmth and a more comfortable feel.
- Keep a Spare Set: Store a complete bedding set nearby so the sofa bed can be made up quickly when needed.
Stock up on sheets and blankets in the Bedding And Bath range to keep a guest-ready set on hand.
6. Upgrade the Pillows and Add a Headboard Substitute
Couch cushions are not a substitute for proper pillows. The right pillows and back support make a sofa bed more comfortable for both sleeping and sitting up.
Pillow and support tips
- Use Real Bed Pillows: Choose pillows based on sleeping style. Memory foam or down-alternative options provide better support and keep their shape.
- Create a Headboard: Place two large, firm cushions behind the pillows to prevent slipping and make sitting up more comfortable.
- Add a Bolster: A long bolster cushion fills the gap at the back and provides extra support for sleeping or lounging.
Tip: Set out a spare pillow or two so guests can adjust their own support rather than making do with what is there.
7. Quiet a Squeaky or Loose Frame
A creaking sofa bed frame can disrupt sleep and usually gets worse over time as the mechanism is used. A few simple checks are often enough to restore smooth, quiet movement.
How to fix it
- Tighten Hardware: Go over all bolts and joints, as loose fittings are the most common source of noise.
- Lubricate Moving Parts: Apply a small amount of lubricant to hinges and folding points to reduce friction and prevent squeaking.
- Test It Early: Open and close the bed before guests arrive to catch and fix any issues in advance.
Tip: Re-check the bolts every few months, especially if the sofa bed is used daily, since regular folding loosens them over time.
8. Choose a Comfortable Sofa Bed from the Start
If you are buying rather than fixing, comfort depends on choosing the right model. Better mechanisms and stronger build quality reduce the need for upgrades later.
What to look for
- Mechanism: Click-clack and fold-down styles create a flat surface without bars underneath, while pull-out designs offer a more traditional bed feel.
- Backrest: Adjustable backrests with multiple positions improve comfort for sitting, lounging, and sleeping.
- Build Quality: A solid frame and higher weight capacity usually provide better support and less sagging over time.
- Useful Extras: Features like USB ports and side pockets add everyday convenience and usability.

A Sofa Bed You’ll Actually Sleep Well On
You do not have to accept a restless night on a sofa bed. Start with a topper and better bedding, add support and fill the gaps, then quiet the frame and place it thoughtfully. If you are starting fresh, choose a model built for comfort from the outset.
FAQs
A good mattress topper is the single most effective fix. A memory foam or latex topper at least 5 cm (2″) thick adds instant cushioning and puts a buffer between you and any bar or springs underneath.
Add support and padding together. Lay a thin board or bunkie board under the mattress to spread the load, then add a thick mattress topper on top. The two combined keep the bar from pressing into your back.
Rolled towels, foam strips or a pool noodle tucked under a deep fitted sheet fill the gaps along the edges. This creates a flatter surface and stops items from slipping down into the frame.
Squeaks usually come from loose bolts or unlubricated moving parts. Tighten all the hardware and apply a little lubricant to the hinges and folding mechanism, then re-check every few months with regular use.
They can be for some sleepers. Click-clack and fold-down styles lie flat without a separate thin mattress on a metal bar, which avoids a common pressure point, while pull-out sleepers give a more traditional mattress feel. The best choice depends on how often it is used and personal preference.
