This Hybrid features a whopping 5 inches of gel memory foam on our supportive but body contouring 896 quantum edge pocketed innerspring for a very conforming yet supportive feel.

We've combined the personal comfort of gel memory foam with the support and durability of an advanced innerspring. The L&K line is built on a coil system, but its not your typical spring mattress. Our pocketed coil technology creates a sleeping surface where springs act independently, isolating movement while still offering increased pressure relief and a custom feel.

Our L&K beds are loaded with memory gel that provides sleeping at the right temperature (to ensure deeper sleep), pressure relief for greater blood flow which means less tossing and turning and more restorative sleep and a more buoyant sleeping surface so you don't have to fight to get in and out of bed

Our quilted L&K mattresses feature memory foam in the quilting (unlike name brands) which means you have the higher density (more durable and more supportive) pressure relieving padding right on top of the sleep surface.

And all of our L&K mattresses have Quantum Edge Technology which makes for better seating support and more usable sleeping space (you can sleep right on the edge of the bed without feeling like you are fixing to fall out of the bed).


  • Pocketed coil technology 1) Individually pocketed spring that act independently of each other and are not linked together with a helical wire to create a sleep surface that not only provides individualized comfort but increased pressure relief and conformability. 2) Individually pocketed spring systems provide the least amount of motion transference of any spring mattress 3) Glued on insulator pad that keeps the springs from migrating and leaking down into the foundation.

  • Quantum edge technology 1) Outer rows of coils are much smaller in diameter all the way around the mattress for a supportive edge and creating a larger sleep surface. 2) By using firmer springs around the mattress instead of a 3 foam encasement (rail), more of the mattress can be used as the sleeping surface and it will retain its comfort from edge to edge. 3) Offers better support and durability than the traditional foam encased edge. 4) Improved air flow and breathability 5) Added flexibility on an adjustable bed

  • Memory gel: Memory gel is the mix of gel (like what is found in premium shoe inserts for cushioning and support) and high density plant based memory foam. We mix the two compounds together in their liquid form and bake them out to make memory Gel. Memory gel is designed to be a better sleeping surface: 1) Memory gel helps to alleviate pressure by cradling your body instead of pushing against your body for superior pressure relief. 2) Its also a more buoyant sleeping surface which allows you to move more easily in (without that stuck feeling) and adds overall support for your body 3) Memory gel absorbs excess body heat and disperses it which allows you to sleep at the optimal sleeping temperature.

  • High density layers of padding: All mattresses have differing types of foams to provide certain feels. This is what makes a firm bed firm and what makes a soft bed soft. These layers are for your comfort and support. 1) We only use high density layers of foam padding. Whether its our super soft or extra firm layers of padding, we only use high quality, high density foam padding. 2) The more dense foam is the more durable it typically is. Density is weight per cubic foot and most mattresses have 1.2 lb-1.5 lb. density foam, but in all of our L & K products we use 2.3 lb. foam or better for more support, comfort and durability. Our foam is heavy but that's a good thing. We use heavier foams than most major name brands so our foam compacts less over a period of time and remains supportive for many years to come.

  • Handles on all four sides: handles are helpful in allowing the mattress to be adjusted on the box springs and for better maneuverability.

    Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

    Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

    Mattresses can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new bedding should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
