Kirkland Stearns & Foster Pillow Top Lakeridge  Mattress Review

The Kirkland Stearns & Foster Pillow Top Lakeridge is advertised as a 14.5-inch (36.8 cm) mattress, but the model we tested was a full inch shorter. Still, you may need to use a deep-pocket fitted sheet. 

This mattress has a Medium firmness level, which puts it in a comfortable middle ground for a range of sleepers. It's a good fit if you're an average-weight or heavier side sleeper, since the surface gives enough to let your shoulder and hip sink in and relieve pressure at those contact points. That said, it's not the best choice for back and stomach sleepers because it doesn't provide enough support. 

The Stearns & Foster Lakeridge has good overall body conformity, making it ideal for side sleeping. The amount of pressure relief you'll receive, however, depends largely on your body weight. It offers the most pressure relief to average-weight and heavier people because they sink deeper into the material. Lighter people won't sink in enough for proper pressure relief and may be better suited to a plusher mattress. 

This mattress doesn't provide great support. It's most supportive for lighter-weight people, who won't sink in far enough into the mattress to bring their hips out of alignment. But as body weight increases, it becomes less supportive and won't foster proper spinal alignment. This means it's not ideal for most back and stomach sleepers. If you're looking for a Costco model that's a better fit, consider the Sealy Posturepedic Pro Highland Manor.

This isn't a particularly bouncy mattress. It pushes back against movement rather than absorbing it, but the pillow top tempers that bounciness, so it will take a little effort to switch positions. 

This mattress does an excellent job of molding closely around your body. You'll sink into the pillow top significantly, and it contours around you quite closely, so you'll feel cradled rather than like you're just resting on top of the mattress

This mattress feels extremely responsive. It bounces back quickly, making it easy to move around or change sleeping positions. 

The Kirkland by Stearns & Foster Lakeridge provides excellent motion isolation, so if you share your bed with a partner or a pet, you shouldn't be disturbed by their movements. You'll mostly feel movement near the source, and the motion settles quickly without causing the mattress to bounce or wobble. 

This mattress offers outstanding edge support. You won't feel like you're about to roll off if you sleep near the edge, which means more usable surface area if you're sharing the bed. 

This mattress offers very good cooling performance. It doesn't feel warm when you first get into bed, and it effectively dissipates heat throughout the night, keeping most people comfortable. If you're a very hot sleeper, though, you might prefer a mattress that offers even better cooling.  

This mattress features reinforced pocket coil edges that provide fantastic edge support. 

This mattress's quilted top blends polyfoam with fiber fill for a soft, plush feel. Below that sits a layer of polyfoam, which adds some responsiveness and bounce near the surface, followed by a layer of memory foam that contributes to the contouring you feel as you sink in further. A polyfoam transition layer sits beneath the comfort layers, preventing you from feeling the coil support system underneath.

Durability is a weak point for this mattress. None of the foam layers meet the density thresholds we look for in long-lasting foam. This means you're more likely to see body impressions and sagging develop in the comfort layers over time compared to a mattress built with denser foam.

The Lakeridge has a substantial amount of material above the spring system, with a thick quilted top followed by two additional comfort foam layers before you reach the transition foam. That extra cushioning gives side sleepers plenty of room to sink in before hitting firmer material underneath. 

The pocket coils making up the support layer are built around Stearns & Foster's patented IntelliCoil HD design. Each individually wrapped coil contains a wider outer coil wrapping a narrower, pyramid-shaped inner coil. Light pressure only compresses the outer coil, but once you sink in far enough, the inner coil engages too, providing more support. At 15 gauge, the wire is considered to have a medium firmness level. 

The quilted top and memory foam layer are both fairly soft, making them ideal for side sleepers, but the layers in between them are a little firmer. The transition foam is then substantially firmer, preventing you from sinking into the coils. 

The support layer's coils have a medium-firm feel. They're slightly firmer at the lumbar region than at the head and feet, providing a bit of extra resistance where the body carries the most weight.

The quilted top, upper comfort foam, and transition layer are all quite resilient and spring back quickly. The memory foam layer sandwiched between them does the opposite, absorbing movement rather than bouncing back. The result is a mattress that feels moderately bouncy and makes it relatively easy to switch positions throughout the night. 

The support spring layer is fairly bouncy. However, with several layers of foam sitting on top, much of that energetic push-back gets absorbed before it reaches the surface, so you won't feel the full bounce of the coils underneath you.
