Best Affordable Mattress for Side Sleepers: What Actually Works
Our recommendations are based on hands-on testing in 5 LA showrooms and feedback from 3,300+ verified customers.
Best Affordable Mattress for Side Sleepers
Side sleeping is the most common sleep position — and also the most demanding on your mattress. Your shoulders and hips take the brunt of your body weight, creating pressure that can wake you up sore if your mattress isn't right.
The good news: you don't need to spend a fortune to sleep well on your side. You just need to know what to look for.
02What Side Sleepers Actually Need
When you sleep on your side, your spine needs to stay in a neutral line from your neck to your tailbone. Two things get in the way:
- Too firm: Your shoulder and hip can't sink in enough, so your spine curves upward at those joints.
- Too soft: Your hips sink too deep, your waist sags, and your spine bows the opposite direction.
A good mattress for side sleepers threads that needle — soft enough to cushion pressure points, supportive enough to keep everything aligned.
The Three Things That Matter Most
- Pressure relief at the shoulder and hip — this is non-negotiable. If a mattress doesn't let your shoulder sink in slightly, you'll feel it.
- Spinal support through the waist — the mattress should fill the gap, not let you collapse into it.
- Motion isolation — if you share a bed, you don't want to feel every movement your partner makes.
03The Right Firmness for Side Sleepers
Most side sleepers do best on a medium to medium-soft mattress — roughly a 4–6 on a 1–10 scale (where 10 is hardest).
| Body Type | Recommended Firmness | Why |
|---|---|---|
| Lightweight (<130 lbs) | Soft to Medium-Soft (3–5) | Less body weight means less natural sinkage |
| Average (130–230 lbs) | Medium to Medium-Soft (4–6) | Sweet spot for most side sleepers |
| Heavier (>230 lbs) | Medium to Medium-Firm (5–7) | More weight needs more resistance to prevent over-sinkage |
04Best Mattress Types for Side Sleepers
Memory Foam
Memory foam is purpose-built for side sleeping. It contours to your body shape, distributes weight evenly, and absorbs motion. The main concern is heat — look for gel-infused or open-cell versions if you run warm.
Latex
Natural latex gives you similar contouring to memory foam but with more bounce and better breathability. It's responsive (you don't feel "stuck"), hypoallergenic, and tends to last longer. Usually a bit pricier, but worth it if budget allows.
Hybrid (Foam + Coils)
Hybrids pair a foam comfort layer (memory foam or latex) with a pocketed coil support system. You get the pressure relief of foam plus the bounce, airflow, and edge support of springs. A solid all-around choice for side sleepers who want more support structure.
Innerspring (Traditional)
Basic innerspring mattresses without a substantial comfort layer are generally not ideal for side sleepers. They don't cushion pressure points well. Pillow-top versions are the exception — the added top layer changes the equation.
05Top Affordable Picks at LA Mattress
Luxe Gel Memory Foam Plush by Venus Mattress
A straightforward gel memory foam mattress with a plush feel tuned for side sleepers. The gel infusion helps regulate temperature, the foam contours to shoulders and hips, and motion isolation is excellent. If you've been sleeping hot on a traditional foam mattress, this is a significant upgrade.
- Best for: Side sleepers who run warm or share a bed
- Firmness: Plush / Medium-Soft
Eclipse Cares Collection Joyfulness Hybrid 11" Plush
A hybrid mattress at a price point that doesn't feel like a compromise. Memory foam comfort layer handles pressure relief; pocketed coils underneath provide support and keep airflow going. At 11", it has enough height to give good contouring without feeling like you're sinking in.
- Best for: Side sleepers who want bounce and support alongside pressure relief
- Firmness: Plush
Harvest Pillow Top Latex by Harvest Green Mattress
If natural materials matter to you, the Harvest Pillow Top is worth considering. Natural latex comfort layer on top provides that springy-yet-contouring feel that latex fans love. It's breathable by nature, sleeps cooler than foam, and the pillow top adds extra cushion at the shoulder and hip.
- Best for: Side sleepers who want eco-friendly materials or prefer latex feel
- Firmness: Plush / Medium-Soft
Englander Supreme Collection Essex Plush 16"
A premium-feeling innerspring hybrid with a deep plush top. The 16" profile gives it a luxurious presence, and the reinforced edge support means you can use every inch of the sleeping surface. More investment up front, but the construction quality justifies it for serious side sleepers.
- Best for: Side sleepers who want a hotel-level feel with strong edge support
- Firmness: Plush
06How to Shop Without Wasting Money
Try Before You Buy
Online mattress shopping is convenient, but side sleeping pressure points are something you feel in person. If you're in LA, visit one of our 5 showrooms and spend 10–15 minutes lying on your side in your typical position. No test equals no guarantee you'll like it at home.
Look for a Real Trial Period
Your body takes 2–4 weeks to fully adjust to a new mattress. A 90–120 night trial gives you time to know for sure. LA Mattress offers a 120-night comfort guarantee — use it.
Don't Ignore the Pillow
Your mattress and pillow work together. A side sleeper needs a pillow thick enough to keep their neck level with their spine. If you upgrade your mattress without rethinking your pillow, you might still wake up with a stiff neck. See our pillow selection for side-sleep-specific options.
Consider a Mattress Topper First
If budget is tight and your current mattress is just slightly too firm, a memory foam or latex topper can provide the extra cushion you need at a fraction of the cost. Not a permanent fix, but a smart interim step.
07Who This Is For / Who It Isn't
This guide is for you if:
- You sleep primarily on your side
- You wake up with shoulder or hip soreness
- You're shopping with a budget in mind
- You're open to different materials (foam, latex, hybrid)
This guide is less relevant if:

- You're looking for ultra-luxury — we have those too, just in a different price range
08Frequently Asked Questions
What type of mattress is best for side sleepers?
Memory foam, latex, and hybrid mattresses are the top choices. All three contour to the body and relieve pressure at the shoulder and hip — the key areas for side sleepers.
How firm should a mattress be for side sleeping?
Medium to medium-soft (roughly 4–6 on a 10-point scale) works for most side sleepers. Very light sleepers may prefer softer; heavier sleepers may need medium-firm to avoid sinking too deep.
Are hybrid mattresses good for side sleepers?
Yes. A good hybrid pairs a foam or latex comfort layer (for pressure relief) with pocketed coils (for support and airflow). It's a well-rounded choice for side sleepers who want more than foam alone.
Do side sleepers need a special pillow?
Yes. Side sleepers need a thicker pillow that keeps the head level with the spine. A flat pillow lets the neck drop; too thick pushes it up. Look for adjustable-fill pillows that let you customize the loft.
How often should a mattress be replaced?
Every 7–10 years on average. Replace sooner if you notice sagging, lumps, or consistent morning pain that wasn't there before.
Can an affordable mattress still be durable?
Yes — durability depends more on material density and construction quality than price alone. High-density foam and natural latex outlast many mid-priced options. We carry affordable options that are genuinely built to last.
What's the advantage of gel memory foam?
Gel infusion helps memory foam dissipate heat faster. Standard memory foam can trap warmth; gel versions sleep noticeably cooler, especially in LA's warm climate.
Is a thicker mattress better for side sleepers?
Not necessarily. What matters more is the thickness and quality of the comfort layer. A 12" mattress with 3" of quality memory foam on top will serve a side sleeper better than a 14" mattress with 1" of foam over cheap padding.
