Shop mattresses by size, feel and construction—from a straightforward guest bed to a configurable hybrid. Compare prices for your chosen size, build a shortlist, then confirm which models you can try at our five Los Angeles showrooms.
Find your starting point
Start with size. Compare construction and feel. Then test your shortlist and plan the complete setup. The mattress with the most features is not automatically the right one for your bedroom.
Allow for the frame’s outside dimensions, open drawers and your walking routes—not only the mattress footprint.
Check your room fit →Use “Prices for” above the grid to choose a size. Add filters for your budget and preferences, then compare the exact options on each product page.
Return to mattresses →Include a compatible foundation, bedding, taxes and applicable fees. Review delivery, exchange and financing terms before ordering.
Plan the complete cost →Construction is a starting point
Materials influence feel, but two mattresses with the same label can sleep differently. Read the model’s specifications and compare comfort in person when possible.
Coils paired with comfort layers. Compare the exact foam or latex layers, edge feel and motion response—not just the word hybrid.
For shoppers who like a contouring feel. Try turning over and compare how quickly the surface responds; cooling claims vary by model.
Often a more buoyant surface. Check whether the mattress is all-latex or a latex hybrid, and verify any material certifications on the product page.
A spring-based support system with comfort upholstery. Coil design and cushioning both matter; innerspring does not automatically mean firm.
A pillow top describes the upper comfort construction, not a separate support system. “Bed in a box” describes packaging—not a firmness or material.
Make room for better choices
Standard U.S. mattress dimensions below. Frame dimensions and model tolerances vary; check the exact product before ordering.
King is wider; California King is longer. Two Twin XL mattresses form a 76 × 80-inch King footprint, but compatible bases and matching heights still matter.
Comfort is personal
A softer surface is not automatically less supportive, and a firmer one is not automatically better. Use these collections to build a shortlist, then test pressure, turning and edge feel.

Visit Koreatown, West LA, La Brea, Studio City or Glendale. Contact your preferred showroom first to confirm which shortlisted models and sizes are on display.
Choose your showroom →Start with the size your room and frame can accommodate, then set a budget for the complete setup. Compare firmness and construction separately. Shortlist a few models, review their exact specifications and terms, and try your usual sleeping positions when possible. There is no one best mattress for everyone.
Both use springs for support. A hybrid combines a coil support system with substantial comfort layers such as foam or latex. Construction labels can overlap, so compare the actual layers, height, feel and support requirements of each model instead of assuming the label determines comfort.
Cost varies with size, construction, brand and options. Use the catalog’s Prices for size control and price filter to compare the size you need. Product pages show the selected configuration and current price. Include the frame or foundation, accessories, taxes, recycling fees and any delivery or removal charges in your total.
Visit our showrooms in Koreatown, West LA, La Brea, Studio City or Glendale. Contact the showroom with your shortlisted model and size before traveling: online inventory and showroom display availability are different. A mattress being listed here does not guarantee it is on display at every location.
No. Firmness describes the surface feel; support depends on the mattress construction and how it works for the sleeper. Test pressure at the shoulders and hips, ease of turning and comfort in your usual position. Labels are not standardized across brands, so compare actual models rather than relying only on a firmness number.
Check the exact mattress manufacturer’s support instructions and your existing frame’s condition, dimensions and slat spacing. Not every mattress works with an adjustable base or the same foundation. Replace or adapt the support only as the manufacturer permits; also check total bed height and delivery access.
Delivery availability, services and charges depend on the order and destination; confirm them before purchase. The 120-night Love Your Bed Guarantee is a comfort-exchange program, not an unrestricted refund promise. Read the linked delivery and exchange terms for current eligibility, timing, fees and exclusions.
