Serta Perfect Sleeper X Quilted Lexton Medium Pillow Top Mattress

Zoned Hybrid Support, Balanced for Medium

The Lexton Medium Pillow Top is part of Serta's Perfect Sleeper X™ Quilted line: a zoned coil support system working together with a graphite-infused memory foam comfort layer under a quilted pillow top. In the Medium feel, the comfort layer and coil layer are balanced evenly, so there's enough cushioning to relieve pressure points without losing the supportive feel of the coils underneath.

It's built with Serta's 5 ZoneResponse™ Design, 1" graphite-infused Perfect Conform™ Memory Foam, and a CoolFeel™ System for a cooler night's sleep.

Why it matters:

  • Heat redistribution — graphite infusion helps move heat away from the body
  • Cooler sleep surface — CoolFeel™ System promotes a consistently cooler feel

Term

The warranty coverage runs from the original date of purchase. Replacement of the mattress or foundation does not extend its limited warranty or begin a new limited warranty period. Your warranty period is based on the code printed on your white law label as indicated on the Warranty Code Chart. The duration of any applicable implied warranties, including but not limited to the implied warranties of merchantability and fitness, shall not exceed the term of this limited warranty.

Serta® shall not be liable for incidental or consequential damages that result from the use of your Serta® product. (Some states do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion may not apply to you.) No expressed or implied warranties are extended to persons who purchase the product from anyone other than Serta Simmons Bedding Company or its authorized dealers, and all warranties to such persons, including the implied warranties of merchantability and fitness, are hereby excluded.

If your Serta® mattress or foundation fails due to a manufacturing defect, the exclusive remedy under this warranty will be replacement of the defective product in the U.S., Puerto Rico or U.S. Virgin Islands.

Perfect Sleeper X Quilted FAQS

This mattress pairs a classic quilted feel with hybrid support: five body zones for alignment, an 850-coil density system for contouring support and motion isolation, 1″ Perfect Conform™ Memory Foam for pressure relief, and a cool-to-the-touch CoolFeel™ fabric cover. Memory foam and cooling upgrades are available on select models.

The support core is zoned so firmness varies by area to promote spinal alignment: more support where your body naturally curves (for example lower back and upper thigh) and appropriate comfort where you make the most contact (shoulders, hips, and lower legs).

Level 1 delivers the quilted hybrid foundation: zoned coils, 1″ Perfect Conform™ Memory Foam, and the CoolFeel™ cover. Level 2 adds up to about 5″ of professional-grade latex-style foam for extra responsive comfort plus a more advanced cooling story—choose the level that matches your budget and how much contouring versus “lift” you want.

Comfort levels vary by level: Level 1 includes options such as Extra Firm, Firm, Plush, Enhanced Plush, and Medium Pillow Top; Level 2 includes options such as Medium, Firm Pillow Top, and Plush Pillow Top. Sizes typically include Twin XL, Full, Queen, King, and California King—confirm availability for the exact model you are viewing.

Yes. The quilted top is paired with a cool-to-the-touch cover made with CoolFeel™ fabric, and select builds add cooling gel swirled into premium memory foam for airflow, heat dissipation, and contouring comfort.

An 850-coil density system delivers cushioning, cradling support and helps limit motion transfer from a partner. BestEdge® Foam Encasement adds a deep foam rail to reduce edge roll-off and extend the usable sleep surface.

When purchased direct from Serta.com, many shoppers receive a 100-night in-home trial and free shipping and returns, plus a 10-year limited warranty against qualifying manufacturing defects. Policies can differ by retailer—always verify at checkout.

It is compatible with most setups, including traditional frames, box springs, platforms, slatted foundations, bunky boards, and adjustable bases—use a supportive foundation that matches the manufacturer’s spacing and weight guidelines.

According to Serta, the Perfect Sleeper X line does not contain fiberglass.

Use a mattress protector to guard against stains and extend mattress life. Do not soak the mattress or apply liquids directly; for spots, sprinkle baking soda, wait about 15 minutes, vacuum, and repeat as needed, and air the bed out when possible. Foams are CertiPUR-US® certified for tested content.
