Body Size Considerations

Your height and build can significantly impact which mattress size will be most comfortable

Under 5'5" (165 cm)

Most mattress sizes will provide adequate length, but consider width based on sleeping position and number of sleepers.

5'5" - 6'0" (165 - 183cm)

Full, Queen, or King sizes are recommended to ensure adequate length for comfortable sleeping.

Over 6'0" (183 cm)

King or California King sizes are strongly recommended to provide sufficient length for taller individuals.

Sleep Position Guide

Your sleeping position affects which mattress size will provide optimal comfort

Side Sleeper

Side sleepers often curl up, taking up less horizontal space but may need room for arm placement.

Recommended Sizes:

Twin/Twin XL – Suitable for individuals who don't move much
Double/Queen – Ideal for most side sleepers
King – Perfect for those who change positions frequently

Back Sleeper

Back sleepers generally maintain a straight position but may need width for arm comfort.

Recommended Sizes:


Twin/Twin XL - Can work but offers limited arm space
Full/Queen - Recommended for most back sleepers
King - Excellent for unrestricted comfort

Stomach Sleeper

Stomach sleepers often extend their arms and legs, requiring more surface area.

Recommended Sizes:


Twin/Twin XL - Too restrictive for most stomach sleepers
Full/Queen - Minimum recommended size
King - Ideal for comfortable stomach sleeping

Combination Sleepers & Couples

Combination Sleepers

If you frequently change positions during sleep, you'll benefit from extra space:

  • Individual sleepers: Full or Queen size recommended
  • Larger individuals: Queen or King size recommended
  • Consider your movement patterns when choosing

Couples with Different Positions

When partners have different sleeping positions:

  • Queen: Minimum recommended size
  • King: Ideal for most couples with different sleep styles
  • Super King: Best for maximum personal space
  • Consider motion isolation features in the mattress

Further Information As Part Of Our Mattress Guide

We don't want to leave you to your own when it comes to choosing the place you want to sleep - we understand it's important, and we want to make sure you're informed of what you purchased and why. Let's dive into a little bit more detail

The Science Of Sleep

Your mattress isn't just a place to rest your head – it's your nightly partner in the complex dance of sleep cycles, body recovery, and brain restoration. While you're dreaming about that vacation you've been planning, your mattress is working overtime to support your spine, regulate your temperature, and ensure you wake up refreshed rather than feeling like you wrestled with a bear.

Quality sleep happens in stages, and your mattress plays a starring role in each one. From light sleep to deep REM cycles, the right support helps your body maintain proper alignment while allowing your muscles to fully relax and recover from the day's adventures.

Why Your Mattress Matters

Poor sleep doesn't just make you grumpy (though we've all been there). It affects everything from your immune system to your ability to remember where you put your keys. A supportive mattress reduces pressure points, promotes proper spinal alignment, and helps regulate body temperature – all crucial factors for achieving that sweet, restorative sleep your body craves.

What Mattress Types Are There?

Choosing a mattress type is like finding your perfect dance partner – you want someone who complements your style and makes you look good (or in this case, sleep good). Each type has its own personality and benefits, so let's meet the candidates.

Memory Foam

Memory foam is like that friend who gives the best hugs – it contours to your body and provides personalized support. Originally developed by NASA (yes, really!), memory foam responds to your body heat and weight, creating a custom sleeping surface just for you. Perfect for side sleepers and anyone who loves that "sleeping in a cloud" feeling.

Memory Foam

Innerspring

Innerspring mattresses are the dependable friend who's always been there for you. They offer excellent support, great airflow for cool sleepers, and that familiar bouncy feel. Modern versions feature individually wrapped coils that provide targeted support while reducing motion transfer – no more feeling your partner's midnight dance moves.

Innerspring

Hybrid

Can't decide between foam and springs? Hybrid mattresses combine the contouring comfort of foam with the support and breathability of coils. You get pressure relief and motion isolation of foam with the support and temperature regulation of springs. It's the diplomatic solution to the great mattress debate!

Mattress Sizes

Size isn't just about fitting in your bedroom – it's about giving yourself the space to sleep comfortably without feeling like you're camping in a tent or swimming in an ocean. Let's find your Goldilocks zone.

Twin and Twin XL For Solo Sleepers

Perfect for kids, teens, guest rooms, or adults who prefer a cozy sleep space. The King Single gives you a bit more room to stretch out – think of it as the "business class" of single beds. Just because you're flying solo doesn't mean you should compromise on comfort!

Full and Queen

These sizes hit that Goldilocks zone – not too big, not too small, but just right for most people. Queens are particularly popular because they offer enough space for couples without overwhelming smaller bedrooms. Plus, you'll have an easier time finding sheets and accessories.
